Causes a freeze the pi when choosing physical pin 4 #14

Closed juggledad closed 6 years ago

juggledad commented 6 years ago

If you use this node and choose to use the physical pins and select pin 4 - which is a ground pin (so this probably applies to the other ground pins too) - as soon as you hit 'depoy' the pi will totally freeze and the only way out is a power off/on.

When you choose physical pins, none of the ground or power pins should be allowed to be selected.

You might want to take a look at the GPIO node to see how it selects pins.

I'll update the doc.

Don't you think you should prevent the selection of the grounding pins?
