Hi guys,
So I’m doing this project that requires TFT display to be a bit away from the microcontroller (I’m using ArduinoMega2560) so I didn’t mount the shield directly but connected it with jumper wires of ~20cm in length. When mounted directly on top of Arduino, the shield worked just fine, however, when attached via jumper wires, only the backlight was on but nothing else worked (100% positive all wires are connected correctly).
What you think could be the problem? Too high voltage drop on the wires? Some wires are a few cm shorter so might that have caused trouble with signals?
Thanks!
Hi there, we suspect the same issue. do you have multimeter to measure Vcc voltage at TFT side after the jumper wire? thanks.
