Thank you for helping with this.
I tried using a separate 5V supply for the screen, but the result was the same (the screen lit up white and the output to the serial monitor looked normal, but no test patterns were displayed). I don’t have an oscilloscope and have no idea how fast the communication is with the display. I have been using Cayenne to plot and save the data online, which seems to work well and takes the place of the screen and SD card for now.
Do you happen to know of a screen and SD card you have used with the Controllino in the past that has worked?
