AVR_2in13c

This library is created for WaveShare 2.13inch white,black,yellow (or red) version of the epaper display.

• Library uses saved in PROGMEM images to display on epaper
• In rle_converter there are two programs: bmp2c and c2rle.
• bmp2c converts monochrome bmp to C array. Note that image has to be rotated to left and then flipped vertically to work.
• c2rle compress array from bmp2c and produce compressed result.

void paper_display(const uint8_t *black, const uint8_t *color);

Send two buffers, black and colored from PROGMEM to the display.

---

void paper_rle_display(const uint8_t *compressed);

Send only black (but can be easily extended for color) buffer to the display, but buffer is compressed with RLE encoding.
