ST7735 for AVR

My simplified plain C version of https://github.com/adafruit/Adafruit-ST7735-Library and parts of https://github.com/adafruit/Adafruit-GFX-Library/

Use at your own risk!

Tweaks

Uses my own bitmap format for fullcolor and monochrome bitmaps
Faster line drawing based on: https://github.com/adafruit/Adafruit-GFX-Library/pull/36
Faster font rendering based on https://github.com/adafruit/Adafruit-GFX-Library/issues/69
Refactored draw_char function that does not load glyph struct twice
