INTRODUCTION
COMPARATOR LABS
The following labs cover some of the fundamental features of the Comparator 1
peripheral found on the PIC16F690, including some unique applications. The
PIC16F690 has two comparators, Comparator 1 and Comparator 2. These peripherals
are very useful mixed signal building blocks, as they provide analog functionality
independent of program execution. This means that, once initialized, no further
firmware is required for a functioning application. The labs in this section will
demonstrate this functionality, then introduce intelligence in the form of additional
firmware to implement a Higher Resolution Sensor Measurement application.
