 I was thinking about the RGB matrix displays, and realized that while I know that the Protomatter code CircuitPython uses to draw them works by scanning the LEDs row by row, I didn't know what that looks like. Normally the matrix is scanned so quickly that our eyes can't see it. I think the target rate is 250 Hertz. So if I wanted to see it in action, I need a high-speed camera. Or would I? I realized that I could just change the source code so that the scan was much slower. So far, we've been looking at the regular image, but with the press of a key, I can switch it to an ultra-low scan rate. Notice how the lines are drawn in pairs, and since the display has 16 lines on it, this makes the scan rate 1 eighth. Each line gets drawn several times with different values. This relates to the binary representation of the RGB pixel values. I think I prefer how it looks normally. Don't you?
