It can be any pin with the possible exception of the open collector
pin. usually portA.4 I believe.

Subject: [piclist] POT command question...

When using the POT command in PicBasic Pro to read a potentiometer,
does the pin that the potentiometer is attached to have to have ADC, or
can any I/O pin be used?

Thanks!

Scott

In old picbasic it used a digital io pin, it sent the pin low, switched
the pin to an input, and timed how long it took to go back to a high
level via a cap/resistor network. this (timed)value was returned.

never used it though!
