I have the official Raspberry 7'' touchscreen already set up to my pi 4 and am running it with the hifiberryos, which just works perfektly fine. Now I want to mount the display upside down and are trying to find out how to rotate the screen with it's touch functionality. Therefore I found the "OFFICIAL RPI TOUSCHSCREEN 7`" post on the comunity page. But I'm not able to find out how to enter the terminal. Or is there another solution to use the "lcd_rotate" command?
A detailed tutorial would be great for my beginner brain :)
Thanks in advance!
