16F616 comparator

Posted: Mon Feb 01, 2010 6:29 am

I need comparator about 1,8 internal Vref, RC3 is input and A2 is output.

Is this OK?

Code:

setup_vref(VREF_LOW|9);
setup_comparator(CP1_A1_VREF);
setup_comparator(CP1_OUT_ON_A2);

Setup statements are not cumulative.

Look in the Comparator section of the 16F616.h file. It says:

Quote:

// OR together one from the first group with one from the second
.
(List of #define statements in "first group")
.
.
.
// and any of the following
.
.
(List of #define statements in "second group")
.
.

Use only one setup_comparator() statement. Combine the constants
with the bitwise-OR operator: |

setup_comparator(CP1_A1_VREF | CP1_OUT_ON_A2);

Yes, that's how you combine the constants.
