Thanks Darrel,

I commented out my ADCON0 = %00000000 and put the loop back in, and confirmed my loop is looping. My result seems to be stuck at 24543, 40910 or 8142 each time I reset. Basically giving me random numbers as best I can tell. But despite the loop looping, the numbers do not change, until I remove power from the unit, then apply power again.

Code:
DEFINE OSC 48

include "modedefs.bas"
include "LCD_3310.pbp"

TRISD = 0
PORTD.0 = 1   'turn on g sensor
PORTD.1 = 0   'select scale for g sensor
PORTD.2 = 0   'select scale for g sensor


TRISA = %00000111   'set porta.0, 1, and 2 as inputs
TRISB = 0
CM1CON = 7
CM2CON = 7
TRISC = 0
TRISE = 0
ADCON0 = %00000001      'turn on adc
ADCON1 = %00000010      'fosc/32 ?? 
'am I translating c language ADCON1=0x10 above correctly?
