I think I'm going nuts.
In this case, last night I was having a problem with a Pic chip.
I'd changed the output pin for one of the serial communication modules. nothing flashy, done it before.
The problem was, it appeared to be giving an inverted output on the original pin as well....
Yellow trace is the output I want, red trace is the old pin - Inverted output right?
Weird right?
I couldn't find any reference to it anywhere, so several hours later I give up and go to bed.
This morning, I rock up with a cuppa... I turn everything on.
That's it.
Nothing else.
It's bloody working.
