Hi,
I have written the processor section for my NRF52 DK board - 8 bit parallel with ILI9486 TFT. Its working but not perfectly - see picture.
The region 0, 0, 240, 240p (approx) seems OK but text or picture (jpeg) exceeding that region shows some artefact.
FillScreen does not seem affected. Screen rotation does not have an effect on the artefact.
I have played with write8 and write16 timing by adding delay here and there without improvement.
Suggestions as to where to look would be appreciated.
Happy holidays,

HI, I saw taht the library suppport generic processor andwas hopping that the Nordic nrf52-DK + ILI9486 8bit parallel display might work. The nrf52-DK is same format as the arduino Uno and I can insert the display directly. When I try to compile exemples, I got the following errors. Any suggestion ?
