Hi everyone,
I am building a control panel with a Raspberry 4 connected to a touchscreen. The problem is that when I press a toggle button, it reacts into half second or more (sometime also 1 second I think). This give an ugly effect, the latency is too high.
I don't have the same effect on PC. Have you got some idea to solve it ?
I already added usbhid.mousepoll=0 option to cmdline.txt, but the problem is not the mouse polling rate because, if I active the mouse pointer, it immediatly moves on the position. The problem is the time intercurring between when mouse pointer is in the position, and when the button changes its state.
Thank you
