#ifdef USE_DISPLAY_TM1637
/*********************************************************************************************\
This driver enables the display of numbers (both integers and floats) and basic text
on the inexpensive TM1637- and TM1638-based seven-segment modules.
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.
For TM1637:
Connect the TM1637 display module's pins to any free GPIOs of the ESP8266 module
and assign the pins as follows from Tasmota's GUI:
DIO hardware pin --> "TM1637 DIO"
CLK hardware pin --> "TM1637 CLK"
For TM1638:
Connect the TM1638 display module's pins to any free GPIOs of the ESP8266 module
and assign the pins as follows from Tasmota's GUI:
DIO hardware pin --> "TM1638 DIO"
CLK hardware pin --> "TM1638 CLK"
STB hardware pin --> "TM1638 STB"
Once the GPIO configuration is saved and the ESP8266/ESP32 module restarts, set the Display Model to 15
using the command "DisplayModel 15"
If your display is a TM1637 with 6 digits, set Display Columns to the number of digits your
display has, using the command "DisplayCols 6" and restart the ESP module.
After the ESP8266/ESP32 module restarts again, the following "Display" commands can be used:
DisplayClear
Clears the display, command: "DisplayClear"
DisplayNumber num [,position {0-(TM1637Data.num_digits-1))} [,leading_zeros {0|1} [,length {1 to TM1637Data.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 TM1637Data.num_digits, 'position' can be 0 (left-most) to TM1637Data.num_digits (right-most).
See function description below for more details.
DisplayNumberNC num [,position {0-(TM1637Data.num_digits-1))} [,leading_zeros {0|1} [,length {1 to TM1637Data.num_digits}]]]
Display integer number as above, but without clearing first. e.g., "DisplayNumberNC 1234". Usage is same as above.
DisplayFloat num [,position {0-(TM1637Data.num_digits-1)} [,precision {0-TM1637Data.num_digits} [,length {1 to TM1637Data.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-(TM1637Data.num_digits-1)} [,precision {0-TM1637Data.num_digits} [,length {1 to TM1637Data.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 {1-8}
Set brightness (1 to 8) command e.g., "DisplayBrightness 2"
DisplayRaw position {0-(TM1637Data.num_digits-1)},length {1 to TM1637Data.num_digits}, num1 [, num2[, num3[, num4[, ...upto TM1637Data.num_digits numbers]]]]]
Takes upto TM1637Data.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-(TM1637Data.num_digits-1)} [,length {1 to TM1637Data.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 TM1637Data.num_digits, 'position' can be 0 (left-most) to TM1637Data.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-TM1637Data.num_digits-1} [,length {1 to TM1637Data.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
