Tweaks
By LongHairedHacker:
- 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
By Massey101:
- Added support for bitmap clipping
- Added JAYCAR screen for XC4629 support
By barskern:

- Set the environment variables for:
AVRMCU- Your avr chipF_CPU- Your clock speedISPPORT- programming device
- Modify
include/st7735.h:st7735_typeto your screen. (I have no idea how to figure out which is which) - Run
make flash
