Expected behaviour
Basically the ILI9341 does not work at all. I am trying to figure out if it's a HW issue (thought it does the same with 2 different units, althought they are from the same order). I just get a black screen, nothing else. I have used the default wiring as described here: https://luma-lcd.readthedocs.io/en/latest/hardware.html#ili9341
Tried running one of the examples: python matrix.py --config ../conf/ili9341.conf
In all cases, I get a blank black screen, no backlight, nothing.
However I can turn on the baclight with a simple python script:
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(12, GPIO.OUT)
GPIO.output(12, 0)
But strangely, when I run the example with the ili9341 config or my own script with the default wiring from the wiki, I don't get anything, not even backlight turning on....
Any ideas? :)
Actual behaviour
Black screen, nothing displayed. I tripled checked all my wiring. And again, at least I would assume the blaclight to be turning on, but not even that is happening. Running a short script using RPi.GPIO works fine however. (It turns on the backlight but the screen still does not show anything)
