- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-Arduino Library for the TM1637 Based LED Display Module
-
-## Description
-This is an Arduino library for 4-digit 7-segment display modules based on the TM1637 chip. 
-Connect the TM1637 display CLK and DIO pins to your Arduino GPIO pins, include this library, initialize TM1637TinyDisplay and call easy to use functions like showNumber(), showString(), showLevel() and showAnimation(). Display will scroll text for larger strings. Functions support screen splitting for easy number + text formatting. Library also runs well on tiny controllers including the ATtiny85.
-
-## Hardware 
-![TM1637](examples/tm1637.png)
-
-Display modules based on the TM1637 chip are available from [HiLetgo](https://www.amazon.com/gp/product/B01DKISMXK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1), [DX](https://dx.com/p/0-36-led-4-digit-display-module-for-arduino-black-blue-works-with-official-arduino-boards-254978) and [SeeedStudio](https://www.digikey.com/products/en?keywords=tm1637). 
-
-![TM1637](examples/tm1637back.png)
-
-The display has four connectors:
-* CLK - Clock - attach to any GPIO output 
-* DIO - Data  - attach to any GPIO output 
-* VCC - Power 5v
-* GND - Ground
-
-Power Note: Steady clean power is important for circuit stability. If you are seeing display artifacts during high frequency updates or animation sequences, you may be experiencing power fluctuations that are impacting signal timing and communication with the TM1637. This is especially true with standalone microprocessor applications that lack any power conditioning (e.g. ATtiny85). A polarized 100uF electrolytic capacitor inserted across VCC and GND can help smooth out the spikes.
-
-Decimals and Colons: Some TM1637 displays come equipped with a middle colon LED (as shown above) as used in digital clocks but with no decimal points. Some displays come with decimal point LEDS for each digit. Some come with both but often the decimal point LEDs are not connected. These extra LEDs are activated by setting the upper bit (0x80) for the digit next to the dot. This library will handle setting that for you via the showNumber() function when you specify floating point numbers or via the showNumberDec() function where you can set the decimal point manually.
-
-## Installation
-This library is available via the Arduino IDE.  Install this library via `Tools`, `Manage Libraries`, search for "TM1637TinyDisplay" and click `Install`.
-
-Alternatively, you can install this manually by cloning this repo into your Arduino library folder (e.g. `~/Documents/Arduino/libraries`).  
-
-## Usage
-The library provides a single class named TM1637TinyDisplay with the following functions:
-
-* `showNumber` - Display an integer and floating point numbers (positive or negative)
-* `showNumberDec` - Display a number with ability to manually set decimal points or colon
-* `showNumberHex` - Display a number in hexadecimal format and set decimal point or colon
-* `showString` - Display a ASCII string of text with optional scrolling for long strings
-* `showLevel` - Use display LEDs to simulate a level indicator (vertical or horizontal)  
-* `showAnimation` - Display a sequence of frames to render an animation
-* `setSegments` - Directly set the value of the LED segments in each digit
-* `setBrightness` - Sets the brightness of the display
-* `setScrolldelay` - Sets the speed for text scrolling
-
-PROGMEM functions: Large string or animation data can be left in Flash instead of being loaded in to SRAM to save memory. 
-
-* `showAnimation_P` - Display a sequence of frames to render an animation (in PROGMEM)
-* `showString_P` - Display a ASCII string of text with optional scrolling for long strings (in PROGMEM)
-
-## Example Code
-```cpp
-#include <Arduino.h>
-#include <TM1637TinyDisplay.h>
-
-// Define Digital Pins
-#define CLK 1
-#define DIO 2
-
-// Initialize TM1637TinyDisplay
-TM1637TinyDisplay display(CLK, DIO);
-
-void setup() {
-  display.setBrightness(0x0f);
-}
-
-void loop() {
-  // Say Hello
-  display.showString("HELLO");
-  delay(500);
-
-  // Clear Screen
-  display.clear();
-
-  // We can count!
-  for (int x = -100; x <= 100; x++) {
-    display.showNumber(x);
-  }
-
-  // Level indicator
-  for (int x = 0; x <= 100; x = x + 10) {
-    display.showLevel(x, false);
-    delay(20);
-  }
-  for (int x = 100; x >= 0; x = x - 10) {
-    display.showLevel(x, false);
-    delay(20);
-  }
-
-  // Split screen for temperature
-  display.showString("\xB0", 1, 3);        // Degree Mark, length=1, position=3 (right)
-  for (int x = -90; x < 200; x++) {
-    display.showNumber(x, false, 3, 0);    // Number, length=3, position=0 (left)
-    delay(10);
-  }
-
-  // The end
-  display.showString("End");
-  delay(1000);
-}
-```
-
-Refer to [TM1637TinyDisplay.h](TM1637TinyDisplay.h) for information on available functions. See also [Examples](examples) for more demonstration.
-
-## Animation and Animator Tool
-The showAnimation() function projects a sequence of frames (patterns) onto the display.  This works by defining the animation sequence through a multi-dimensional array of patterns.  
-
-You can use the included javascript based interactive [7-Segment LED Animator Tool](https://jasonacox.github.io/TM1637TinyDisplay/examples/7-segment-animator.html) to help build your animation. The source code is in the [Examples](examples) folder.  This tool will let you set up the LED sequences you want, save each frame and copy the final code (a static array) directly into your sketch to use for the `showAnimation(data, frames, timing)` function.  Here is an example:
-
-```cpp
-// Data from Animator Tool
-const uint8_t ANIMATION[12][4] = {
-  { 0x08, 0x00, 0x00, 0x00 },  // Frame 0
-  { 0x00, 0x08, 0x00, 0x00 },  // Frame 1
-  { 0x00, 0x00, 0x08, 0x00 },  // Frame 2
-  { 0x00, 0x00, 0x00, 0x08 },  // Frame 3
-  { 0x00, 0x00, 0x00, 0x04 },  // Frame 4
-  { 0x00, 0x00, 0x00, 0x02 },  // Frame 5
-  { 0x00, 0x00, 0x00, 0x01 },  // Frame 6
-  { 0x00, 0x00, 0x01, 0x00 },  // Frame 7
-  { 0x00, 0x01, 0x00, 0x00 },  // Frame 8
-  { 0x01, 0x00, 0x00, 0x00 },  // Frame 9
-  { 0x20, 0x00, 0x00, 0x00 },  // Frame 10
-  { 0x10, 0x00, 0x00, 0x00 }   // Frame 11
-};
-
-  // Display Animation sequence
-  display.showAnimation(ANIMATION, FRAMES(ANIMATION), TIME_MS(50));
-
-```

-    7-Segment LED Display Animator Tool

-
-    Description: 
-        This tool will allow the user to visually toggle on/off LEDs in a 4-digit
-        7-segment display to create a pattern.  It will show the hexadecimal and binary
-        value for the pattern.  The user can then SAVE the pattern as a frame in an
-        animation sequence which will show up in the "Animation Data" section below 
-        the controls. The user can then PLAY back the animation on the display. Once
-        complete, the user can COPY the code to their clipboard and paste the data
-        into their sketch.  Designed for the Arduino TM1637TinyDisplay library available
-        for download in the Arduino IDE or via GitHub: 
-            https://github.com/jasonacox/TM1637TinyDisplay

-//  TM1637TinyDisplay DEMO Sketch for ATtiny85
-//  This is a demo sketch for the Arduino TM1637TinyDisplay LED Display library
-//  Designed for small memory processors like the ATtiny85
-//
-//  Author: Jason A. Cox - @jasonacox
-//  Date: 2 July 2020
-//
-//  Based on TM1637Display library at https://github.com/avishorp/TM1637
-//
-
-// Includes
-#include <Arduino.h>
-#include <TM1637TinyDisplay.h>
-#include <avr/pgmspace.h>
-
-// Define Digital Pins
-#define CLK 4
-#define DIO 5
-
-// Initialize TM1637TinyDisplay
-TM1637TinyDisplay display(CLK, DIO);
-
-// Animation data below was created with the Animator Tool located here:
-// https://jasonacox.github.io/TM1637TinyDisplay/examples/7-segment-animator.html
-// To save RAM space, we store the animation sequences in PROGMEM read-only flash memory.
-// This requires using the showAnimation_P() function to read from PROGMEM memory space.

-# TM1637TinyDisplay Examples
-
-## Test Sketch
-The [TM1637Test.ino](TM1637Test/TM1637Test.ino) sketch will test the library functions.
-
-## Demo Sketch
-The [TM1637Demo.ino](TM1637Demo/TM1637Demo.ino) sketch will demonstrate the library functions
-and play an extended set of animation sequences.  The animations were built with the [Animator Tool](https://jasonacox.github.io/TM1637TinyDisplay/examples/7-segment-animator.html) referenced below.
-
-## Animation 
-
-### 7-Segment LED Display Animator Tool
-![Animator Tool](AnimatorToolThumb.png)
-
-This tool will allow the user to visually toggle on/off LEDs in a 4-digit
-7-segment display to create a pattern.  It calculates the hexadecimal and binary
-values for the pattern.  You can SAVE the pattern as a frame in an
-animation sequence which will show up in the "Animation Data" section below 
-the controls. To see the animation, press the PLAYBACK button. Once
-complete, press the COPY button to copy the code to your clipboard and paste the data
-into your sketch. 
-
-[https://jasonacox.github.io/TM1637TinyDisplay/examples/7-segment-animator.html](https://jasonacox.github.io/TM1637TinyDisplay/examples/7-segment-animator.html)
-
-### Animation showAnimation() Function
-The showAnimation() function projects a sequence of frames (patterns) onto the display.  This works by provide the function a multi-dimensional array of patterns.  
-
-As mentioned above, you can use the javascript based interactive [7-Segment LED Animator Tool](https://jasonacox.github.io/TM1637TinyDisplay/examples/7-segment-animator.html) to help build your animation. The source code is in this single-file HTML: [7-segment-animator.html](7-segment-animator.html) which you can run from your local file system or a website.  This tool will let you set up the LED sequences you want, save each frame and copy the final code (a static array) directly into your sketch to use for the `showAnimation(data, frames, timing)` function.  Here is an example implementation:
-
-```cpp
-#include <Arduino.h>
-#include <TM1637TinyDisplay.h>
-
-// Define Digital Pins
-#define CLK 4
-#define DIO 5
-
-// Initialize TM1637TinyDisplay
-TM1637TinyDisplay display(CLK, DIO);
-

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc., <http://fsf.org/>
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    {description}
+    Copyright (C) {year}  {fullname}
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  {signature of Ty Coon}, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+
+
+Arduino library for controlling a TM163x based 7-segment display module. These modules are sold under various names by various suppliers. For example:
+
+* [Seed Studio: Grove 4 digit display](http://www.seeedstudio.com/depot/grove-4digit-display-p-1198.html)
+* [Ebay: 4 Bits Digital Tube LED TM1637](http://www.ebay.com/sch/i.html?_odkw=4+Bits+Digital+Tube+LED&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X4+Bits+Digital+Tube+LED+TM1637.TRS0&_nkw=4+Bits+Digital+Tube+LED+TM1637&_sacat=0)
+* [DealExtreme: LED 4-Digit Display Module](http://www.dx.com/s/TM1637)
+
+They come in different sizes, colors and there is a clock (with a colon) and decimal (with four decimal dots) display variant. But the most common one is the red 0.36" clock version, this is also the cheapest one (you can get those for about $1.50). I've written this library using the above module, if I get my hands on any of the other variants I might add some specific code, for example to print floats on the decimal version.

+# Installation
+
+Like any other Arduino library this library is installed by copying the files into a directory on the Arduino IDE search path. Most common is to put all files in a director in `your sketch folder/libraries/SevenSegmentTM1637/`. See [installing additional Arduino libraries](https://www.arduino.cc/en/Guide/Libraries) for more information.
+
+# Usage
+
+This library uses the [LCD API v1.0](http://playground.arduino.cc/Code/LCDAPI) so you can use the same functions/methods using this library as any lcd library which conforms to the LCD API. Furthermore this library (like described in the LCD API) inherent the Print class (See [Serial.print()](https://www.arduino.cc/en/Serial/Print) and for more details [Print.h](https://github.com/arduino/Arduino/blob/master/hardware/arduino/avr/cores/arduino/Print.h)). This means that you can use all Print class functions/methods like you're used to when you're doing `Serial.print("Something")` or `Serial.print(128, BIN)` for example.
+
+## Basic methods
+
+* `SevenSegmentTM1637(clkPin, dioPin)`Creates a display object
+* `init()`              Initializes the display
+* `print(value)`        Prints anything to the display (e.g. a string, number..)
+* `clear()`             Clears the display (and resets cursor)
+* `home()`              Resets cursor
+* `setCursor(row, col)` Set the cursor to specified position
+* `setBacklight(value)` Sets the brightness of the display
+* `on()`                Turn the display on (set brightness to default)
+* `off()`               Turns the display off (set brightness to zero)
+* `blink()`             Blinks what ever is on the display
+* `setColonOn(bool)`    Sets the colon in the middle of the display
+* `setPrintDelay(time)` Sets the delay when printing more than 4 characters
+
+## Advanced methods
+
+* `encode()`    Encodes a single digit, single char or char array (C string)
+* `printRaw()`  Prints raw byte(s) to the display
+* `command()`   Sends one or more raw byte commands to the display
+
+## Low level methods
+
+* `comStart()`            Serial communication start command
+* `comWriteByte(bytes)`   Serial communication send byte command
+* `comAck()`              Serial communication get acknowledged command
+* `comStop()`             Serial communication stop command
+
+If you still want or need more functionality, I've included two super classes:
+
+* `SevenSegmentExtended()`  Extends the base class with more usefull functions.
+* `SevenSegmentFun()`       Even more extensions for fun.
+
+If you use any of these super classes, you will also get all the basic, advanced and low level methods as well. If you use the fun class extension you will get the extended class methods as well.
+
+## Extended class extra methods
+
+* `SevenSegmentExtended(clkPin, dioPin)`        Creates a display object
+* `printTime(hour, min, [blink], [blinkDelay])` Prints the time to the display
+* `printTime(time, [blink], [blinkDelay])`      Prints the time to the display
+* `printDualCounter(leftValue, rightValue)`     Prints two digits to the display
+
+## Fun class extra methods
+
+* `SevenSegmentFun(clkPin, dioPin)`           Creates a display object
+* `printLevelVertical(level, [leftToRight])`  Print 0-100% (2 steps per digit) vertical level e.g. volume, battery
+* `printLevelVertical(level, leftToRight, symbol)`  Print 0-100% (1 step per digit) vertical level using custom symbol
+* `printLevelHorizontal(levels[])` Prints 4 horizontal levels e.g. equalizer
+* `scrollingText()`             Prints text and (keeps) scrolling
+* `snake()`                     Classic snake demo
+* `nightrider()`                Nightrider Kit demo
+* `bombTimer()`                 Count down a (bomb) timer
+* `bouncingBall()`              Bouncing ball demo
+
+For more extended information on what arguments all above functions accept and return see the header files of the classes (SevenSegmentTM1637.h, SevenSegmentExtended.h and SevenSegmentFun.h).
+
+# Trouble shooting
+
+* Some boards might not have enough power on their 5V pin. In that case try to use an external 5V power supply. People reported that the ESP8266 might be one of those boards.
+
+# Todo
+
+* Refactor library to make it more modular and support more chips
+  + Add support for all TM16xx chips (most should already work)
+  + Add support for MAX7219 displays
+  + Add support for TM74HC595 displays
+
+# Changelog

+
+# Note
+
+I spend quite a bit of time to build this library. I hope it will be useful to others. I decided to publish it, although there still might be small bugs. If you find one, just let me know and I will try to fix it. If you have any other suggestion, don't hesitate to contact me.
+
+# Sources
+
+I've looked at many sources while constructing this library, bassicly all alternative Arduino TM1637 libraries and some AVR TM1637 libraries. While doing so I've found some really nice improvements compared to other implementations. For example, most libraries use a really low clock speed (~50us), I've tested with clock speeds as low as 1us and the chip still seems to respond well. Furthermore, from the (Chinese) datasheet it seems that you always have to perform three operation when communicating with the IC; set some configuration, set the address and send 1-4 digit data and set the display brightness. I've found out that this is not the case, you can do all of those separately if you want.
+
+Still without all these fine examples it would have taken me a lot more time to figure out the inner workings of this IC!

+* Structure
+* START COMMAND ACK STOP                  set config or display
+* START ADR_CMD DATA ACK STOP             sets single digit
+* START ADR_CMD DATA0 .. DATAN ACK STOP   sets multiple digits when in auto mode
+*
+* There are basicly three things you can do:
+*   1. Set some configuration values
+*     - read/write mode, auto/manual address, normal/test mode
+*   2. Set a (starting) address followed by 1 or N data bytes
+*   3. Set the display brightness (pwm) 0-7 and on or off
+*
+* From the datasheet it might seem that you always have to perform all three commands; setting configuration, setting address and data bytes and display. I'v tested this and this is not true. You can just set only one of these three. But ofcourse you have to make sure that your configuration is set properly. For example if you haven't set the configuration to automatic addresses, you can't just send out 4 data bytes, it won't work. Simlilair, if your display is off and you write some data to it, it won't display. On the other hand most default setting are what you want most of the time.

+sentence=Library for using a 4 digit seven segment display with TM1636 or TM1637 driver IC
+paragraph=Extensive library for controlling a 4 digit seven segment display. This library inherent the Print class and uses the LCDAPI 1.0. For example you can use all normal Print methods like: print() and println(). From the LCDAPI among others begin(), clear(), home(), setCursor() and setBacklight() are implementend. On top of these regular functionality a segerate fun class which adds more features can be used. For example a bombtimer(), nightrider() and bouncingBall() method can be used when using the fun class.
