AVRTFT

Project to drive a TFT LCD like the
Adafruit 1.8" Color TFT LCD 160x128 ST7735R
with an AVR MCU (ATmega328P) and avr-libc.

Currently implemented:

  • Nearly complete UTF-8 set (code points U+0000 to U+00FF) of GNU Unifont
  • Small subset of large glyphs in DejaVu: 0-9 and some special characters
  • Store font and bitmaps in program memory instead of RAM
  • Draw strings in Unifont and DejaVu
  • Draw bitmaps
  • Write text and bitmaps via USART
  • Logging via USART

Thanks to:

Write something via USART

Connect to the controller with for example GTKTerm (9600 Baud).
Write some text and a bitmap:
