Project to drive an E-Ink display like the Adafruit Monochrome 2.13" 250x122 SSD1680 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
- Use SRAM as frame buffer
- Fast and full update mode
- Draw strings in Unifont and DejaVu
- Draw bitmaps
- Write text and bitmaps via USART
- Logging via USART
Thanks to:
- https://github.com/adafruit/Adafruit_EPD for helping me out with the display initialization!
- https://github.com/markbirss for telling me that fast update mode is supported!
- https://github.com/sprintersb for helping me to improve the code and making it more efficient!
Connect to the controller with for example GTKTerm (9600 Baud).
Write some text and a bitmap:
c 0 // clear display
t 0 0 d 0-9 // write text in DejaVu (large) to row 0 column 0
t 2 128 u Small text in // write text in Unifont (small) to row 2 column 128
t 4 128 u Unifont // write text in Unifont (small) to row 4 column 128
t 8 0 d !#%*+,-° // write text in DejaVu (large) to row 8 column 0
b 7 198 0 // write bitmap with index 0 (Tux) to row 7 column 198
u 1 // update display in fast update mode (0 = full update mode)
