I haven’t been able to work on my photon project for a couple of months now because of work and new (much) longer commute However, I did get a few minutes to look at my project over the weekend. I’m still having the same problem with the display getting corrupted after a few minutes.
I remember looking at these threads
But I’m not sure what the next step is - has anyone tried adding the 2 microsecond delay to the adafruit library? Is there some other solution that is working for folks using this display?
