Hi
I have a problem where incorrect pixels are lit by the half brightness.. If I lit a pixel, say (0,1), by dmd.setPixel(0, 1) the pixel (0,1) is lit by full brightness, but also the pixel above (0,0) will get lit by half the brightness. The problem only applies to every second row of pixels.
This is the result of dmd.drawLine(0, 0, 31, 7) https://i.imgur.com/dzdcsVj.png, as you see some pixels are incorrectly lit.
I am using an Arduino Leonardo and unsoldered cables from Arduino to the display.
Any idea what goes wrong?
