Just bought one of the new Unicorn Hat HD’s from Adafruit, and ran into a small problem – everything seems to work correctly with the exception of one pixel – the pixel at coordinate (5, 3) (assuming zero-based coordinates with origin at the upper left) seems to be defective as it cannot display any of the red channel of any particular color.
I have attached a picture of the Pi running the candle.py example script, you can easily see the green pixel in among the other flame-colored pixels.
What are my choices here?
