I have been trying without success to get my Displayotron to show anything :(
I am running a RPi3 with “Raspbian GNU/Linux 9 (Stretch)”
After having performed a
sudo apt-get update and
upgrade, following the instructions here:
https://learn.pimoroni.com/tutorial/display-o-tron/getting-started-with-display-o-tron, seems to be causing me issues.
The script runs from, however it advises that it is unable to install
smbus, that support for this OS is experimental.
I have tried running the basic python scripts. The hello_world.py one runs with a message stating in the terminal that “Hello world” should be displaying, and then saying to hit Ctrl+C to exit, but just terminates anyway.
The backlight.py script produces a 121 : Remote I/O Error.
Can somebody point me in the right direction with this? The Displayotron would be a cool piece of kit if I can get it working :D
