Hi,

I had to connect the RESET pin to VDD to get my display working. You can also connect the RESET line to a GPIO on the nRF52 that you set high during init, in case you want to reset the display from your application.

Best regards,
Jørgen

Hi,

I'm not aware of any tutorials or guides, but the GFX library documentation along with the API documentation should be a good starting point.

Best regards,
