Tracked in Issue 35 this epaper took some trial and error to get it running since the Waveshare demo file did not have the right SPI commands. Only the black version is implemented but it won’t be hard to get the red/black working. It has a very nice resolution, costs almost the same as the V2 version 800*480, having 10% more resolution. Fonts render very nice using Adafruit GFX and our class.
#include <gdew075HD.h>

void app_main(void)
{
display.init(true); // Activate debug
display.setRotation(0); // Optionally change rotation
// Write something
display.setCursor(10,100);
display.println("CalEPD the epaper component you can trust");
// Type display.* to discover more of the inherited GFX functions fillCircle, fillTriangle, etc

We are also launching a new company called Marespa.es that will help EU citizens find an affordable apartment in Spain. With the price of Rent going through the roof in 2024, this might be the moment to make an investment, if you plan to work from the spanish coast. With this project we are also supporting our open source projects.
