i have a Hyperpixel 4.0 Touchscreen, which i use one my Raspberry PI 3b+ This Touchscreen is attached directly on the 40 GPIO-Pins and a few Pins have some special Alt-modes. Out of personal Interest, I want to know more about which GPIO pin has which alt mode. Is someone able to provide me this information or tell me, how or where i can search the Alt-Mode on my raspberry pi?
Thanks
