Hello everyone
Does anyone here have the Waveshare 4inch SPI Display (SKU: 10207) running on the RPi5 and was able to communicate with the display via python script? So far, I'm completely failing.
I've connected the Display via GPIO Header and downloaded the drivers from Waveshare, found here:
https://github.com/waveshare/LCD-show.git
Then I've done:..as stated in the Wiki (https://www.waveshare.com/wiki/4inch_RPi_LCD_(A)).
When I run this example code, I get the following errors:Output:I've read, that it might be related to the new RPi5 Hardware and to changes how to use GPIO, but I'm missing a hint, where to start. Any ideas?
