Display Commands~

See commands page for full list of available Display Commands


The display driver is able to display predefined setups of text or user defined text. To display text using DisplayText set DisplayMode to 0, or set DisplayMode to 1 for the HT16K33 dot-matrix display.

To use the seven-segment-specific TM1637, TM1638 and MAX7219 or TM1650 Display- commands, set DisplayMode to 0.

The DisplayText command is used to display text as well as graphics and graphs on LCD, OLED and e-Paper displays (EPD). The command argument is a string that is printed on the display at the current position. The string can be prefixed by embedded control commands enclosed in brackets [].

In order to use the DisplayText command the DisplayMode must be set to 0 (or optional 1 on LCD displays) or other modes must be disabled before compilation with #undef USE_DISPLAY_MODES1TO5.

The DisplayText command is customised for the TM1637, TM1638 and MAX7219 or TM1650 seven-segment display modules. This is documented here and here.

Up to 4 line charts may be defined.

Ticks may be defined by adding tick numbers to the n parameter.


n = graph number (0..3) + x ticks (16*number of x ticks) + y ticks (1024*number of y ticks).

  • Gsn:path: = save graph n to path (if optional file system is present)
  • Grn:path: = restore graph n from path (if optional file system is present)

Batch files~

When a file system is present you may define displaytext batch files. If a file named "display.bat" is present in the file system this batch file is executed. The file may contain any number of diplaytext cmds, one at a line. You may have comment lines beginning with a ;


; clr screen
; draw full screen picture
; define index color
; draw transparent text with new index color over picture
A displaytext batch file may be executed from console by displaybatch /file

Color Codes~

While computers and web design are generally using a 24-bit RGB888 color code built from a byte-triplet such as (255, 136, 56) or #FF8038, small color panels often use a more compact code 16-bit RGB565 color code. This means that the R, G and B coefficient are coded on less number of bits:

  • Red on 5 bits = 0..31
  • Green on 6 bits = 0..63
  • Blue on 5 bits = 0..31

For Cp and Bp, p is calculated as p = 2048 * Red + 64 * Green + Blue


Red 50% + Green 20% + Blue 100% = 2048 * 16 + 64 * 12 + 31 = 33576 equivalent to web #8033FF

Common colors table:

Color Code Color Code Color Code
Black 0 Navy 15 Dark green 3
Dark cyan 1007 Maroon 30720 Purple 30735
Olive 31712 Light grey 50712 Dark grey 31727
Blue 31 Green 7 Cyan 2047
Red 63488 Magenta 63519 Yellow 65504
White 65535 Orange 64800 Green yellow 45029
Pink 64536

Color Indices~

Selected with Ci and Bi in the ILI9488, SSD1351, RA8876 and ST7789 color panels

Index Color Index Color Index Color

You may expand the index color table up from index 19 to 31. the cmd [dcI:V] defines the index color with index I (19-31) to the 16 bit color value V

Note on e-Paper Displays~

E-Paper displays have 2 operating modes: full update and partial update. While full update delivers a clean and sharp picture, it has the disadvantage of taking several seconds for the screen update and shows severe flickering during update. Partial update is quite fast (300 ms) with no flickering but there is the possibility that erased content is still slightly visible. It is therefore useful to perform a full update in regular intervals (e.g., each hour) to fully refresh the display.

Compilation directives: #define USE_SPI, #define USE_DISPLAY, #define USE_DISPLAY_EPAPER29, or #define USE_DISPLAY_EPAPER42

Remark: the 4.2 e-Paper display requires about 15k of RAM. Therefore it only works with Core 2.42 and above.

OLED Lifetime~

The typical specifications for the lifetime of an OLED when permanently on is about 10000 hours (416 days). Dimming to 50% expands the lifetime to about 25000 hours.


The data sheets of the TFT and OLED displays mention burn-in effects when a static display is shown for extended periods of time. You may want to consider turning on the display on demand only.


The EPD font contains 95 characters starting from code 32, while the classic GFX font contains 256 characters ranging from 0 to 255. Custom characters above 127 can be displayed. To display these characters, you must specify an escape sequence (standard octal escapes do not work). The ~character followed by a hex byte can define any character code.



Hardware Connections~

I2C displays are connected in the usual manner and defined via the GPIO component selection.

The I2C address must be specified using DisplayAddress XX, e.g., 60. The model must be specified with DisplayModel, e.g., 2 for SSD1306. To permanently turn the display on set DisplayDimmer 100. Display rotation can be permanently set using DisplayRotate X (x = 0..3).

On SPI the CS and DC pins when needed must use the pin definition with Display_ID + CS e.g. ST7789_CS

E-Paper displays are connected via software 3-wire SPI (CS, SCLK, MOSI). DC should be connected to GND , Reset to 3.3 V and busy may be left unconnected. The jumper on the circuit board of the display must be set to 3-wire SPI.

The ILI9488 is connected via hardware 3-wire SPI (SPI_MOSI=GPIO13, SPI_SCLK=GPIO14, CS=GPIO15) and must also be connected to the backlight pin The SSD1351 may be connected via hardware 3-wire SPI or 4-wire SPI with support for dimmer. The ILI9341 is connected via hardware 4-wire SPI, Backlight and OLEDRESET (dimmer supported on ESP32) Wiring

The RA8876 is connected via standard hardware 4-wire SPI (SPI_MOSI=GPIO13, SPI_SCLK=GPIO14, RA_8876_CS=GPIO15, SSPI_MISO=GPIO12). No backlight pin is needed, dimmer supported, on ESP32 gpio pins may be freeley defined (below gpio 33).

The ST7789 is connected via 4 Wire software SPI ((ST7789_CS), SSPI_SCLK, SSPI_MOSI, ST7789_DC, OLEDRESET, Backlight )

Rule Examples~

For scripting examples see Scripting Cookbook

WaveShare Display Drivers~

Waveshare has two kinds of display controllers: with partial update and without partial update. The 2.9 inch driver is for partial update and should also support other Waveshare partial update models with modified WIDTH and HEIGHT parameters. The 4.2 inch driver is a full update display.

epaper displays should be connected via software SPI. most of them require a reset and a busy line. connect the busy line to SSPI_MISO.

The drivers are subclasses of the Adafruit GFX library. The class hierarchy is LOWLEVEL :: Paint :: Renderer :: GFX, where:

  • GFX: unmodified Adafruit library
  • Renderer: the interface for Tasmota
  • Paint: the modified pixel driver for e-paper
  • there are several virtual functions that can be subclassed down to LOWLEVEL

The display dispatcher only does the class initialization call. All other calls go to the Renderer class.

In black and white displays, a local RAM buffer must be allocated before calling the driver. This must be set to zero on character or TFT color displays.

The EPD fonts use about 9k space, which can be selected at compile time using #ifdef directives.

  • SSD1306 - 1.15k
  • EPD42 - 2.57k
  • EPD29 - 2.1k
  • Display and Render class - ~12k

Universal Display Driver~

Universal Display Driver or uDisplay is a way to define your display settings using a simple text file and easily add it to Tasmota. uDisplay is DisplayModel 17. It supports I2C and hardware or software SPI (3 or 4 wire), 8,16 Bit parallel and RGB interface. The driver must be enabled by OPTION A3 on any GPIO pin.

The driver is enabled by compiling with #define USE_UNIVERSAL_DISPLAY and setting an unused GPIO to Option A3.

Descriptor File~

The display itself is defined by a descriptor file. Many display descriptor files are included in Tasmota GitHub in tasmota/displaydesc folder

which may be provided by any of the following methods:

  1. A display.ini file present in the flash file system. preferred option
  2. A special >d section in scripting. Copy the file to the >d script section and place a ->displayreinit cmd into >B section
  3. Copy the descriptor to Rule 3 but do not enable it (descriptor may not contain ANY spaces in this mode)
  4. Compile the descriptor into the binary in a section in user_config_override.h under driver 17 (const char)

Options 2 and 4 work well for 1M flash devices.

Descriptor text file has the following elements:

  7. g0-g5 pins (green color)
  8. r0-r4 pins (red color)
  9. Pixel clock Speed in MHz (usually 14)

All signals must be given. Unused pins may be set to -1. If you specify a * char the pin number is derived from the Tasmota GPIO GUI.
The CS and DC pins must be the standard pins e.g. SPI_CS or SPI_DC.

there are RGB displays that also need an SPI initialisation. in this case specify the Init sequence with :IS,SCLK,MOSI,CS,RESET
there are RGB displays that also need an I2C initialisation. in this case specify the Init sequence with :II,BUS,ADDR (BUS = i2c bus nr 1 or 2, ADDR = adress of i2c device)
