Comparator setup for Microchip 16F684

[elellilrah]

Hello,

What is the correct hex number to set up the comparators on the Microchip 16F684 using A1 and A0 in the off state and using C1 - C0 with the output C2OUT? The mode from the data sheet is:

CM<2:0> = 101.

The code generated from the supplied 16F684.h file does not have this option. When I use the PIC Project Wizard, the code generated defaults to:
setup_comparator(NC_NC).

Thanks!

P.S. Also, if anyone can supply what the different nibbles in the 0xnnnnn hex number represent in the setup_comparator() function, that would be even better because the 16F684.h file only seems to have a few of the possible modes.

What version are you using?

Version 4.053 works with no problems.

setup_comparator(NC_NC_C1_C0);

In the header file:
#define NC_NC_C1_C0 0x10FF05

I am using 3.241 and those files don't have that information in there. I will try your hex code in there and see if it works.

Thanks!

The op-code you provided worked perfectly, thank you.

I need to find a more recent copy of the full 16F684.h file as it must have several changes in it.
