I would like to connect a ER-TFTM035-6 3.5" 480x320 TFT display board to an Adafruit Arduino Huzzah32 esp32 based board.
I connected the power, ground and backlight control to 3.3v and Gnd on the Huzzah32. I connected the CS and DC to those pins and the SPI pins.
The only library I could find that seemed to have ILI9488 support is the TFT_eSPI library, so I installed that.
I opened the UTFT_Demo_480x320.ino example. I set all the pins in the User_Setup.h file according to the pins I wired up.
When I power the Huzzah32 the screen lights up so I have the backlight working right.
As the sketch runs the screen is white and then flashes sort of black / gray from for several seconds. Then it just stays white for a few seconds. Then flashes some more.
Anyone have any experience with this configuration or something close? What might I be doing wrong?
I am hoping it is just some define I didn't set that needs to be.
