How to use comparator on PIC18F4520
PostPosted: Wed Apr 21, 2010 2:32 am     Reply with quote
Hi,

I would like to, if it is possible, to use comparator on PIC18F4520 to compare Voltage on some input port with Value I defined in source code.

Any help would be grateful.

Thanks

You can use this program as an example:
http://www.ccsinfo.com/forum/viewtopic.php?t=22955&start=1
This program has a 5K trimpot on pin A0. By turning the trimpot, the
voltage on that pin can be changed in the 0v to 5v range.

Also, the pins in the #use rs232() statement need to be changed to pins
C6 and C7 for the 18F4520.
