I have a micro and sinks the current to a 3.3 V LED via 220 ohms to turn it on. It works but as soon as I put my scope probe on the LED (micro side) the LED doesnt turn on. What can cause that?

How is a schematic going to help with a firmware issue?

So, you think that a guy that got firmware for turning an LED on wrong actually wired it correctly?
