Member Function Documentation
void EPD_Display_KWR | ( | unsigned char const * | img_kw, |
unsigned char const * | img_r | ||
) |
Display image with color: black, white and red.
Resolution of EL029TR1 is 128x296. Pixel data alignment is from left to right and from top to bottom.
img_kw point to black and white raw pixel data of image, 1 bit per pixel, 0 = black, 1 = white, Total size of img_kw is 128x296/8 = 4736 bytes for EL029TR1.
img_r point to red raw pixel data of image, 1 bit per pixel, 0 = red, 1 = reserved, Total size of img_r is 128x296/8 = 4736 bytes for EL029TR1.
- Parameters:
-
img_kw point to black and white raw pixel data of image, 1 bit per pixel, 0 = black, 1 = white,
img_r point to red raw pixel data of image, 1 bit per pixel, 0 = red, 1 = reserved,
- Returns:
- none
