Chapter 7. ANALOG.C Description7.1 Introduction

This chapter describes the demonstration program for the PIC17C756A,

ANALOG.C. This program continuously converts on channel 0 (which is

connected to a precision 4.096V voltage reference) and displays the resu lt in

ASCII on the Monitor program. The A/D module is configured to use the AVDD

and AVSS pins as the voltage reference.
