I have five OLEDs. They sometimes work. Not presently with any consistency.

Ok... Reference the original thread - I connected a display and see some errors...

I went back to my configuration GUI and brought all settings I had tweaked to defaults and it worked... Did get hung up once and had to be rebooted......

@markyharris Understood... Was asking how to utilize the light sensor without the level converter... Thanks

Thanks, Mark! How then would the schematic change for the light sensor? It appears to use a 3.3 pin on the RPI.
