Implementation example
This 2.13" small epapers from Good display are used in the Lilygo TTGO T5 models. I like the fact that refreshes are quite fast and also partial update that is hard to get working seems to be doing its job here. Only tested a few times, needs more real testing, so if you have one around please try it out.
#include <gdeh0213b73.h>
// Two lines to start IO and instantiate your model
EpdSpi io;
Gdeh0213b73 display(io);
void app_main(void) {
display.init(true);
display.setRotation(0);
display.println("Hello world");
// Print a 2 pix line
for (int i = 0; i < display.width(); i++) {
display.drawPixel(i,10,EPD_BLACK);
display.drawPixel(i,11,EPD_BLACK);
}
