I´m trying to use the Display-O-Tron on a Raspberry Pi 3 Model B. The main purpose of this Pi is running as an emulation station for my kid. Retropie and 10,000 games plus Kodi and Kodi extensions have been installed so I really don´t want to have to start from a blank SD card just to use the Display-o-Tron. I have updated to the latest version of Raspbian and did the one line install. I got the message in the terminal that everything was completed ¨Enjoy your Display-o-Tron 3000/HAT!¨. The display did not light up. Rebooted, same result. Updated again and installed the displayotron software again. Same result.
I entered cd ~/Pimoroni/displayotron/examples-backup, then sudo ./joystick.py and got the message command not found.
from dot3k import lcd
Gives the message ¨can´t read /var/mail/dot3k¨
from dot3k import backlight
Gives the same message
I´m wondering if the unit might be DOA
