12F675 two ports ADC
PostPosted: Sat Dec 05, 2009 12:21 am     Reply with quote
I want to use two ports of PIC12F675 ADC. I know how to use a single channel. But in 12F675.h file its written:
Code:

// Constants used in SETUP_ADC_PORTS() are:
#define sAN0                   1         //| GP0
#define sAN1                   2         //| GP1
#define sAN2                   4         //| GP2
#define sAN3                   8         //| GP4
#define NO_ANALOGS             0         // None

How to set two ports for ADC ????

The sANx constants are OR'ed together. For an example, look at the
setup_adc_ports() line in this post:
