Using the pic12F683

[TonyA]

Thank you.

For this particular chip the ANSEL is used instead of ADCON1?

Would I still need to set up the ADCON0 if the ANSEL is set up?

Would you only disable the analog comparator when using a digital input?


Here's what I have now:

DEFINE OSC 8 'Oscillator speed in MHz
DEFINE ADC_BITS 10
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 15
OSCCON = %01110000 ' Set internal OSC to 8MHz
ANSEL = %00001111 ' Set AN0-AN3 analog, rest digital
TRISIO.5 = 0 ' GP5 is output
ADCON0.7 = 1 ' Right justify for 10 bit result

INTCON = %00000000 'all interrupts OFF



Thanks again,
Tony

Hi Tony,

You don't necessarily have to set these pins to inputs with TRISIO before
using ADCIN, but it definitely is good practice to do so.

Pins are inputs by default at power-up, but I always include TRIS statements
in code just to be 100% sure the pin is an input before reading it.
