I have been messing around a bit with a 128x64 OLED like these:
These are cheap and work great. I use these on my programmable guitar foot pedals.
I was able to get one of these working on the TIPI...
See for yourself. I'm going to set it up to automatically run after the TIPI is booted.
I will be adding buttons to power the PI up if you need to as well as for it to perform a clean shutdown.
Just thought I would share.
I'll be typing up a procedure on how I did it. It takes about 10 minutes.
I may make the font bigger and only list the IP address and TIPI Ready. Hell I may tool a small PCB for it all to just plug in to the correct GPIO pins on the Pi2/3
