How to work with inbuilt Analog Comparators of PIC18F4550

Analog comparator is an electronic device which compares the two voltage signals and provides TTL logic output to indicate the larger signal. The analog comparator is used in various applications where two inputs signals need to be compared. IR sensor is a very common example where analog comparator is used. PIC18F4550 has two in-built comparators which can be used in eight different modes. These in-built c ...
