I am just wondering what spotify connect client you're using in this project? looks like maybe librespot? does the API allow for operational player controls for the touchscreen? (Play/pause/skip etc.)
I have a 3.5' DSI display attached https://www.waveshare.com/wiki/3.5inch_DSI_LCD_(H)
and it is displaying fine and touch works but the image is in portrait and it appears that the touch is in landscape, so I'd like to either turn thr display 90 counter-clockwise or turn the touch 90 ...
