Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Ahh me again,

of course I first looked into the manual, but it states only:

Specifies which pins are to be used as Count inputs.
By default these are GP6, GP7, GP8 and GP9.
The SETPIN command defines the Counter mode.
This command must be run at the command prompt (not in a program).


Problem: I don't have as many Pins left. My project consumes already all pins and
GP2 (pin 4) I have reserved for this job. Why I am forced to enter 4 Pins?

I lerned from another topic that it is possible to leave them "blank" like:

OPTION COUNT , , ,GP2
 

but then I get an SYNTAX ERROR...

I am afraid by just taking "random" Pins (which are already used by my program) I am introducing other conflicts or errors.

I just need one Pin as a Counting, and that's GP2, is that possible?

Best wishes and forgive my noobness! Sadly the manual doesn't tell me about that specific case..

Just specify any pins. If you don't use them as count pins it is completely benign.

Thank you, I thought if they are already in use there might be problems later on ...

Greetings
