Example is out of date

[kattni]

The miniqr_displaytest.py example is out of date and no longer works.

displayio.Sprite was replaced by displayio.TileGrid. Simple fix.

Less simple: displayio.Bitmap has been updated to no longer use _load_row, and instead addresses each pixel individually. The displaytest example needs to be updated to use the new displayio API.

The new API is utilised in Adafruit_CircuitPython_PyPortal.
