I am working with an ILI9341 based Touch Screen display, and I have the display part working very nicely. But I can’t find a Photon compatible driver for the resistive touch screen component.
The touch screen is completely independent from the display part, and both are SPI driven.
I am using Hardware SPI for the display.
The resistive touch controller seems quite common and the XPT2046 can replace ADS7843E TSC2046 ADS7843 ADS7846 RSM1.
FWIW, the display units are very nice. They are SPI 3 or 4 wire, 8 bit or 16 bit parallel, touch screen, SD card slot, extra memory available and accept font chips:
Does anyone know of a successful implementation on the Photon for one of these touch chips?
