/*********************************************************************************************\
This driver enables the display of numbers (both integers and floats) and basic text
on the inexpensive TM1637-, TM1638- and MAX7219-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"
For MAX7219:
Connect the MAX7219 display module's pins to any free GPIOs of the ESP8266 module
and assign the pins as follows from Tasmota's GUI:
DIN hardware pin --> "MAX7219 DIN"
CS hardware pin --> "MAX7219 CS"
CLK hardware pin --> "MAX7219 CLK"
Once the GPIO configuration is saved and the ESP8266/ESP32 module restarts,
set the Display Model to 15 and Display Mode to 0
using the command "Backlog DisplayModel 15 ; DisplayMode 0"
If your display is a TM1637 with 6 digits, set Display Width to the number of digits your
display has, using the command "DisplayWidth 6".
After the ESP8266/ESP32 module restarts again, turn ON the display with the command "Power 1"
Now, the following "Display" commands can be used:
DisplayClear
Clears the display, command: "DisplayClear"
DisplayNumber num [,position {0-(Settings->display_width-1))} [,leading_zeros {0|1} [,length {1 to Settings->display_width}]]]
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 Settings->display_width, 'position' can be 0 (left-most) to Settings->display_width (right-most).
See function description below for more details.
DisplayNumberNC num [,position {0-(Settings->display_width-1))} [,leading_zeros {0|1} [,length {1 to Settings->display_width}]]]
Display integer number as above, but without clearing first. e.g., "DisplayNumberNC 1234". Usage is same as above.
DisplayFloat num [,position {0-(Settings->display_width-1)} [,precision {0-Settings->display_width} [,length {1 to Settings->display_width}]]]
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-(Settings->display_width-1)} [,precision {0-Settings->display_width} [,length {1 to Settings->display_width}]]]
Displays float (with decimal point) as above, but without clearing first. command e.g., "DisplayFloatNC 12.34"
See function description below for more details.
DisplayRaw position {0-(Settings->display_width-1)},length {1 to Settings->display_width}, num1 [, num2[, num3[, num4[, ...upto Settings->display_width numbers]]]]]
Takes upto Settings->display_width 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-(Settings->display_width-1)} [,length {1 to Settings->display_width}]]
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 Settings->display_width, 'position' can be 0 (left-most) to Settings->display_width-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-Settings->display_width-1} [,length {1 to Settings->display_width}]]
Clears first, then displays text. Usage is same as above.
DisplayScrollText text [, num_loops]
Displays scrolling text indefinitely, until another Display- command (other than DisplayScrollText
or DisplayScrollDelay is issued). Optionally, stop scrolling after num_loops iterations.
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
In addition, setting DisplayMode to 1 shows the time, setting it to 2 shows the date
and setting it to 3 alternates between time and date.
