The built-in scope doesn't entirely work how you'd expect. In particular, it does not present any nodes, so you can't attach to it. This is especially confusing for those of us who had used the old oscilloscope module which did work that way...

Anyway, the inability to add a signal with a right click in the gui is a bug, which will probably be sorted at some point. Meanwhile, the correct syntax for the command line is:

scope.ch0 = "portc6"
scope.ch1 = "portd0"
scope.ch2 = "portd1"
scope.ch3 = "portd2"

As you'd expect, this sets up four channels monitoring bit 6 of port C and the bottom three bits of port D (the project I took it from uses a 16F871). It connects to processor pins, not nodes. So for your case, you want:

scope.ch0 = "porta1"

Thanks a lot, that works great!

Merci,
