GxEPD2_AVR

Simplified Version of GxEPD for AVR Arduino

for SPI e-paper displays from Dalian Good Display

and SPI e-paper boards from Waveshare

important note :

- these displays are for 3.3V supply and 3.3V data lines

- never connect data lines directly to 5V Arduino data pins, you may use e.g. 4k7 series resistor

Paged Drawing, Picture Loop

- This library uses paged drawing to cope with RAM restriction and missing single pixel update support

- Paged drawing is implemented as picture loop, like in U8G2 (Oliver Kraus)

- see https://github.com/olikraus/u8glib/wiki/tpictureloop

Supporting Arduino Forum Topics:

Version 1.0.6

  • added GxEPD2_AVR_SD_BitmapExample
  • Support for Bitmaps (Sprites) to Controller Buffer and to Screen
  • the bitmaps can reside in RAM or ROM, parameter pgm, default RAM
  • origin x and width should be multiple of 8, are rounded down
  • cropping to screen dimensions is handled
  • allows tiled drawing for bitmaps from SD, SPIFFS or WiFi download
  • use e.g. writeImage(...) for each tile, followed by refresh() for all

Version 1.0.2

Version 1.0.1

  • Example Bitmaps & 4.2" b/w fast partial update
You can’t perform that action at this time.
