Re: Lib for ILI9486 - 3.5 inch 480x320 touch TFT for RPi

I would suggest to use the LCD reg test sketch from David, it helps to check your wiring.
And paste here the result from the serial monitor.

Re: Lib for ILI9486 - 3.5 inch 480x320 touch TFT for RPi

Is it a 2.4 inch display?
Which pins do you use for the data bus?
I see that it has 8 bit bus, so you should could use the 8 bit parallel library.

The files can be found here: https://github.com/stevstrong/Adafruit_TFTLCD_16bit_STM32 I tested it with my black F4 board. The cu...
