#111169 - I disagree Responding to: ???'s previous message |
It will help greatly if you can run separate chip and LED supply lines. And add LOTS of supply decoupling by the chip.
I disagree! the above is NOT correct The fact is You are never going to get it ot work if you do not run separate chip and LED supply lines. You will have enough trouble with ground bounce. Erik |
