[Solved] Newbie question digitalWrite to MEGA pins 10-13

Using Arduino Programming Questions

hoytf:
The MEGA that I am using contains a jumper that allows the MEGA to use (a) shields designed for the Mega or (b) shields designed for the UNO/Ruggeduino. If the jumper is set for MEGA shields, D10-D13 operate properly. On the other hand, if the jumper is set for UNO shields, D10-D13 are used for other functions.

All I had do do to solve my problem was to move the jumper.

If the jumper is in the Mega position, do pins 50 to 53 work?

Well, OK. PM me, and I'll send you my address where you can send your board, and I'll test it.

Paul, pins 50 to 53 work fine with the jumper set to the MEGA position.

That was not what I expected. Thanks for testing.
