Hello,
I want to use C2 comparator of PIC16F628A. Please could anyone to explain me the two below commands. Pin RA2 has a stable voltage at 2,5V (Vref) and pin RA1 is my analog input. The pins RA0 and RA3 I used as digital inputs. What means VR? Thanks.

VR means voltage reference. Section 11 of the datasheet gives a full
description of the internal Voltage Reference module. See 10.3.2 and figures
11-1 and 11-2. Also note in 11.2 that internal VRef is affected by changes in
VDD which affects accuracy. _________________ Google and Forum Search are some of your best tools!!!!

I write the below command and works perfect.
Code:
setup_comparator(NC_NC_A1_A2); // Turn on Comparator C2.
