I bought a display-o-tron. Software all installed following the setup command without any trouble, but when I run any of the samples (or my own simple script for hello world) I found half the display lights up, and no text appears. Basically the LEDs for the left hand side of the display illuminate, but not the right. I can change the colour of them with the RGB command (although it seems to interpret as BGR?) but no text ever appears.
I assumed a faulty board, and Pimoroni kindly sent me another, but it behaves exactly the same. Now assuming my Pi is perhaps faulty, I brought the display to work and connected to another Pi 2 B (using my existing SD image) but it’s the same!
Now, I’m figuring that it’s pretty unlikely two display boards are broken in exactly the same way - likewise two Pi’s - so I’m assuming it’s maybe a software problem.
I’m not getting any error messages though! Any suggestions for tests I can do to ensure everything is configured correctly?
