Hello Jon,

I simplified the program for my learning. Here is what happens:

After programming it I plugin the USB cable into my computer. The RX lights flashed for a few seconds and than no more. But it should continue to flash as it runs a infinite loop. Th eouput pin looks fine, I checke with my scope.

The same happens in the debugger, the LED for the pin flashed a few times and than goes solid. I tried with PAUSE 500 and it's the same. It should blink, right?
