are suggesting adding decoupling capacitors?
but I will try with a capacitor between power and ground on the powersupply today.
since the LM317 delivers constant current and the outputs of the tlc5940 delivers constant current I would be safe
Is there a way to calculate value for pull ups though by the way?
You can parallel up the outputs of the TLC do a search for application note SLVA280 Using TLC5940 With Higher LED Supply Voltages and Series LEDsandSLVA253 LED Driver [ch8211] Paralleled Outputs Provide High-Current Outputs
Could I use an N-channel MOSFET on the 4 paralleled output pins?
