QUESTION: open-smart ILI9320 not support #20

Closed chaoshendasixiong closed 2 years ago

chaoshendasixiong commented 2 years ago

i got a tft lcd ili9320 and Wemos D1 ESP32, i have changed RS CS RST pins from 35,34,36 to 15,33,32 menuconfig select 9320, but is doesn't work, always white. Is it not suitable for OPEN-SMART Products? should i giveup to use another lcd or any recommend driver type?

I don’t have open-smart ILI9320 2.8 inch TFT.

I2S parallel may not work for OPEN-SMART Products.

Try changing the interface to GPIO parallel.

OPEN-SMART Products have different pin arrangements from general TFT shields. You have to change GPIO assign.
