A library to drive PCD8544, HT1621, ST7735, ST7789, ST7567, UC1701X and ILI9341-based LCD displays
HD44780, PCD8544, ST7735, ST7789, ST7567, HT1621, UC1701X, ILI9341 Display Drivers
luma.lcd provides a Python 3 interface to small LCD displays connected to Raspberry Pi and other Linux-based single-board computers (SBC). It provides a Pillow-compatible drawing canvas, and other functionality to support:
- scrolling/panning capability,
- terminal-style printing,
- state management,
- color/greyscale (where supported),
- dithering to monochrome
It currently supports devices using the HD44780, PCD8544, ST7735, HT1621, and UC1701X controllers.
All modules can be picked up on ebay with a breakout board for a few pounds.
Full documentation with installation instructions and examples can be found on https://luma-lcd.readthedocs.io.
Version 2.0.0 was released on 2 June 2019: this came with the removal of the luma.lcd.aux.backlight class. The equivalent functionality has now been subsumed into the device classes that have a backlight capability.
