I am working on a new design and i am using ST7789 (240 X 320 pixels) screen with nRF52840, it is working fine. I have followed the code provided in SDK example (big thanks).
But it is painfully slow, is there a way to make it faster considering nRF52840 has a powerful processor and good memory.
Any guidance will be much appreciated. Due to cost and complexity i wanted not to use a secondary processor.
