Henrick,

I see what you mean, I took the wrong example for what I wanted, messed with it and by pure luck
it worked if I used it where/when I needed it and not used in a GOSUB!

I tried your code example and it worked for five "start" button presses and then the same problem
where the RD pin doesn't stop pulsing at 65535 and just keeps running on.

Thanks for your time and help,

Jim
