circuitpy CPB and TFT Gizmo black screen

Post by mrendon »

Hi. I'm a beginner so I'm probably doing something wrong. I've been able to get this working with the TFTGizmo and Circuit Playground Bluefuit.
https://learn.adafruit.com/adafruit-tft ... quickstart

I'm trying to get https://learn.adafruit.com/circuitpytho ... y-a-bitmap to run. And I'm getting a black screen.

I found https://github.com/adafruit/Adafruit_Ci ... /issues/10 . and I also tried running slideshow_tft_gizmo.py running and it's doing the same thing.

I couldn't get it to work with a circuit playground express and the tft to work with the arduino sketch either fwiw

Thanks!
