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?

[@ballinlikebill8334]

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?

[@g.r.bstudio4564]

How to print the images in the display.

[@MaxGoddur]

Can this board be used with the four wire connection two of which are gnd and power?

[@MohammedRezwanulIslam]

No. The spi bus needs 4 wire + gnd + power. Minimum 6 wires are needed.
