I have just started to build up another WeatherDuino Pro2 PLUS AT2560 receiver for my home weather setup, but I cannot get anything to show up on the display I’m using (2.8 SPI TFT (ILI9341), the ones I have are from ebay and are exactly as pictured in the “warning about some 2.8 SPI TFT (ILI9341) displays on eBay” thread on the right hand side.
I am using Arduino 18.8 & AVR Board Manager 1.6.21 get no compilation errors, the output on the serial monitor is expected, I just get nothing on the display other than the backlight illuminating.
I have 2 of these displays, both are the same, I have tested them both with the Adafruit library & test code and both work, although I can’t get them to work with the TFT_ILI9341 library and example code either.
My original working Pro2 Plus RX unit is using the display with the yellow pin connector, but I am reluctant to disturb that for fear of breaking it!
I have checked my wiring several times, but all seems fine.
I have a spare Meduino Mega2560 Pro-mini board somewhere I’ll try to find that and see if perhaps my other one is faulty.
Any help with fault finding would be most welcome!
