Reply To: Cant get piscreen to work

[tarumaycry]

Hi Mark,

Thanks for responding so fast.

1) Ive tried both positions, but definitively i dont know which state is on and which is off. (unless the piscreen needs to be on the on state prior to being turned on)
2) Ive completed that tutorial, with the exception of step 4
3) crw-rw—T 1 root video 29, 0 Jan 1 1970 /dev/fb0
