Nice work 👍
Thank you so much.
Hola, intenté comunicar con el código de ejemplo que dejaste en el vídeo pero el display se mantiene en negro, ¿Falta el código del loop o estoy fallando en inicializar el display?
Can you share your code to fill the whole screen? I got the beginning working but cant figure out how to fill the screen with one color?
How to print the images in the display.
Can this board be used with the four wire connection two of which are gnd and power?
No. The spi bus needs 4 wire + gnd + power. Minimum 6 wires are needed.
This is I2C
