ST7735 Display
ST7735 Display Driver.
Usage
The ST7735 component allows you to use a ST7735 display (datasheet and information, Adafruit) in ESPHome. It uses the SPI Bus for communication.
⚠️ Warning
This component has been made redundant since the ST7735 is now supported by the MIPI SPI Display Driver. This component will be removed in a future release.
There are numerous board types out there. Some initialize differently as well. This driver will take a few options to narrow down the right settings.
# Example configuration entry
display:
- platform: st7735
model: "INITR_18BLACKTAB"
reset_pin: D4
cs_pin: D1
dc_pin: D2
rotation: 0
device_width: 128
device_height: 160
col_start: 0
row_start: 0
eight_bit_color: true
update_interval: 5sConfiguration variables
model (Required, string): The model to use, one of the following options:
INITR_BLACKTABINITR_GREENTABINITR_REDTABINITR_MINI160X80INITR_18BLACKTABINITR_18REDTAB
cs_pin (Required, Pin Schema): The CS pin.
dc_pin (Required, Pin Schema): The DC pin.
device_width (Required, int): The device width. 128 is default
device_height (Required, int): The device height. 160 is default
col_start (Required, int): The starting column offset. Default value depends on model.
row_start (Required, int): The starting row offset. Default value depends on model.
use_bgr (Optional, boolean): Use BGR mode. Default is false.
invert_colors (Optional, boolean): Invert LCD colors. Default is false.
eight_bit_color (Optional, boolean): 8bit mode. Default is false. This saves 50% of the buffer required for the display.
reset_pin (Optional, Pin Schema): The RESET pin.
update_interval (Optional, Time): Time between display updates. Default is 1s.
Memory notes
- 8Bit color saves 50% of the buffer required.
eight_bit_color: true160x128 = 20480 Important for memory constrained deviceseight_bit_color: false160x128x2 = 40960
