IR Overlay - pulling hair out !
Hi everyone … i have built my MM frame and am using a old 32"LCD TV , sitting on top i have a 32" IR Touch overlay … but the overlay responds to touch in landscape mode - i have a pi4 and have rotated the TV screen using DISPLAY=:0 xrandr --output HDMI-1 --rotate left , but despite looking at loads of forums / websites nothing seems to work to make the touch overlay rotate as well … my overlay is Bus 001 Device 003: ID 1ff7:0013 CVT Electronics.Co.,Ltd CVTouch Screen (HID)
Any help greatly appreciated !!!
@emailuser well, here is a concise description of how to do it with a pi screen and overlay…
two different configs…
DISPLAY=:0 xrandr --output HDMI-1 --rotate left
Thanks Sam … but those instructions are for a touchscreen – i have an IR USB overlay which enables touch on the screen ,
as an example on the instruction
Enter sudo nano /etc/modules at the command prompt to edit the file. Go to the line for the ads7846_device parameters and move the cursor to the right to find it: - i dont have that in that file
