Hardware Triggering of ADC

In this exercise you will:

Configure the XC2000 with DAvE

Assign a potentiometer to an ADC cannel

Define ADC parameters

Develop a program that will trigger ADC conversion by hardware

Hardware Triggering of ADC

Exercise goal:

Trigger ADC conversion by T13 overflow of CCU60

The onboard potentiometer is connected to channel 0

(P5.0)

A/D converter will run in hardware triggered autoscan

mode

Use T13 period match of CCU60 to trigger ADC conversion Output A/D results on Port P10 (LED display)
