snake eyes issues

by wizzard333 on Thu Sep 24, 2020 2:41 pm

Hello, I just purchased and built the snake eyes kit with the tft 240x240 screens.
I set everything up per instructions and can only get one screen to display. (left eye)
While the right screen has power and the back light lights it has no output. I switched my screens to see if it was a bad screen and again only the left eye was working.
I double a triple checked my connections and they seem to be clean. I also swapped the cables to see if it was that and the issue followed the same pattern. Could someone give me an Idea what the world is wrong? Thanks, Walt

Exact same issue and same initial troubleshooting process. Any insight would be appreciated.

Ok, solved for me, anyway. I must have messed up in the initial config as there was a line in /etc/rc.local for gpio-halt

Commenting this out now has both eyes functioning properly.

# /usr/local/bin/gpio-halt &
/boot/Pi_Eyes/fbx2 -i &
cd /boot/Pi_Eyes;python3 eyes.py --radius 240 &
exit 0
