/*********************************************************************************************\
|
||||
This driver enables the display of numbers (both integers and floats) and basic text
|
||||
on the inexpensive 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_MAX7219, or build the tasmota-display env.
|
||||
|
||||
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 16
|
||||
using the command "DisplayModel 16"
|
||||
|
||||
After the ESP8266/ESP32 module restarts again, the following "Display" commands can be used:
|
||||
|
||||
|
||||
DisplayClear
|
||||
|
||||
Clears the display, command: "DisplayClear"
|
||||
|
||||
|
||||
DisplayNumber num [,position {0-(MAX7219Data.num_digits-1))} [,leading_zeros {0|1} [,length {1 to MAX7219Data.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 MAX7219Data.num_digits, 'position' can be 0 (left-most) to MAX7219Data.num_digits (right-most).
|
||||
See function description below for more details.
|
||||
|
||||
DisplayNumberNC num [,position {0-(MAX7219Data.num_digits-1))} [,leading_zeros {0|1} [,length {1 to MAX7219Data.num_digits}]]]
|
||||
|
||||
Display integer number as above, but without clearing first. e.g., "DisplayNumberNC 1234". Usage is same as above.
|
||||
|
||||
|
||||
|
||||
DisplayFloat num [,position {0-(MAX7219Data.num_digits-1)} [,precision {0-MAX7219Data.num_digits} [,length {1 to MAX7219Data.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-(MAX7219Data.num_digits-1)} [,precision {0-MAX7219Data.num_digits} [,length {1 to MAX7219Data.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-(MAX7219Data.num_digits-1)},length {1 to MAX7219Data.num_digits}, num1 [, num2[, num3[, num4[, ...upto MAX7219Data.num_digits numbers]]]]]
|
||||
|
||||
Takes upto MAX7219Data.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-(MAX7219Data.num_digits-1)} [,length {1 to MAX7219Data.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 MAX7219Data.num_digits, 'position' can be 0 (left-most) to MAX7219Data.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-MAX7219Data.num_digits-1} [,length {1 to MAX7219Data.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
