Ok I now switched to ShiftPWM to see if I still have the issue with a dedicated pin per color and when ShiftPWM.SetAll(0); or ShiftPWM.SetRGB(0,0,0,0); is called it still does not turn off all the way. Instead it just gets dimmer. I attached a picture of my board, that is the led turned "off".
Hello guys! I was wondering why my common anode rgb leds will not turn off fully with the ShiftMatrixPWM lib. The way I have it hooked up is the common anode of each led in each row is connected then controlled by the row pin. and the same thing for the col. When I measure the voltage out when its off its not putting out the 5v that it needs to turn fully off. It is putting out 4.55v on one of the red col pins when ShiftMatrixPWM.SetAll(0); Any ideas?
