#ifdef USE_DISPLAY_TM1637
/*********************************************************************************************\
This driver enables the display of numbers (both integers and floats) and basic text
on the inexpensive TM1637-based seven-segment modules (tested on both 4- and 6-digit variants).
Raw segments can also be displayed.
In addition, it is also possible to set brightness (8 levels), clear the display, scroll text, display
a rudimentary bar graph, and a Clock (12 hr and 24 hr).
To use, compile Tasmota with USE_DISPLAY and USE_DISPLAY_TM1637, or build the tasmota-display env.
The pins to use are "SSPI MOSI" and "SSPI SCLK".
Connect the TM1637 display module's DIO and CLK pins to any free GPIOs of the ESP8266 module
and assign the pins as follows from Tasmota's GUI:
DIO hardware pin --> "SSPI MOSI"
CLK hardware pin --> "SSPI SCLK"
Once the device restarts the following "Display" commands become available:
DisplaySize size {1-6}
Sets the number of digits to use. This is typically set to the actual number of digits available
in the display module. command e.g., "DisplaySize 6"
DisplayClear
Clears the display, command: "DisplayClear"
DisplayNumber num [,position {0-(NUM_DIGITS-1))} [,leading_zeros {0|1} [,length {1 to NUM_DIGITS}]]]
Clears and then displays number without decimal. command e.g., "DisplayNumber 1234"
Control 'leading zeros', 'length' and 'position' with "DisplayNumber 1234, <position>, <leadingZeros>, <length>"
'leading zeros' can be 1 or 0 (default), 'length' can be 1 to NUM_DIGITS, 'position' can be 0 (left-most) to NUM_DIGITS (right-most).
See function description below for more details.
DisplayNumberNC num [,position {0-(NUM_DIGITS-1))} [,leading_zeros {0|1} [,length {1 to NUM_DIGITS}]]]
Display integer number as above, but without clearing first. e.g., "DisplayNumberNC 1234". Usage is same as above.
DisplayFloat num [,position {0-(NUM_DIGITS-1)} [,precision {0-NUM_DIGITS} [,length {1 to NUM_DIGITS}]]]
Clears and then displays float (with decimal point) command e.g., "DisplayFloat 12.34"
See function description below for more details.
DisplayFloatNC num [,position {0-(NUM_DIGITS-1)} [,precision {0-NUM_DIGITS} [,length {1 to NUM_DIGITS}]]]
Displays float (with decimal point) as above, but without clearing first. command e.g., "DisplayFloatNC 12.34"
See function description below for more details.
DisplayBrightness num {0-8}
Set brightness (0 (off) to 8) command e.g., "DisplayBrightness 2"
DisplayRaw position {0-(NUM_DIGITS-1)},length {1 to NUM_DIGITS}, num1 [, num2[, num3[, num4[, ...upto NUM_DIGITS numbers]]]]]
Takes upto NUM_DIGITS comma-separated integers (0-255) and displays raw segments. Each number represents a
7-segment digit. Each 8-bit number represents individual segments of a digit.
For example, the command "DisplayRaw 0, 4, 255, 255, 255, 255" would display "[8.8.8.8.]"
DisplayText text [, position {0-(NUM_DIGITS-1)} [,length {1 to NUM_DIGITS}]]
Clears and then displays basic text. command e.g., "DisplayText ajith vasudevan"
Control 'length' and 'position' with "DisplayText <text>, <position>, <length>"
'length' can be 1 to NUM_DIGITS, 'position' can be 0 (left-most) to NUM_DIGITS-1 (right-most)
A caret(^) symbol in the text input is dispayed as the degrees(°) symbol. This is useful for displaying Temperature!
For example, the command "DisplayText 22.5^" will display "22.5°".
DisplayTextNC text [, position {0-NUM_DIGITS-1} [,length {1 to NUM_DIGITS}]]
Clears first, then displays text. Usage is same as above.
DisplayScrollText text
Displays scrolling text.
DisplayScrollDelay delay {0-15} // default = 4
Sets the speed of text scroll. Smaller delay = faster scrolling.
DisplayLevel num {0-100}
Display a horizontal bar graph (0-100) command e.g., "DisplayLevel 50" will display [|||| ]
DisplayClock 1|2|0
Displays a clock.
Commands "DisplayClock 1" // 12 hr format
"DisplayClock 2" // 24 hr format
"DisplayClock 0" // turn off clock
