It's driving me crazy: I have one (well, two actually) of those 1.8" SPI TFT displays and I just can't get it to work properly.
Usually, it will only display a white background (BG LED) - so I tried several TFT libraries, 3 different Arduinos (Nano, Diecimilia, Mega), both displays and also added 1kOhm resistors to the data lines (read it in another thread) to test.
The interesting part is when I use the Adafruit_QDTech library or the UTFT-based example sketch provided by QDTech, the display will actually show it's content whenever I press the "reset" button on the board - but only for a second or so since the board is restarting
But that tells me that at least my wiring seems to be correct and the display is actually working.
Has anybody got any ideas?
