Issues chaining Adafruit 12-Channel 16-bit PWM LED Driver - TLC59711
I have these 12 channel LED boards working fine driving LEDs controlled by an Arduino however when chaining them I get some strange behaviour where I see a faint flash of the corresponding LEDs on all adjacent boards when they should be off. So for example, if board 1 R0 is set to zero, when board 2 R0 is set to turn on (more noticeable the higher the PWM value) then board 1 LED R0 gives a notable flicker. This is really annoying for my application. Any ideas how to stop this?
