    Default Re: How do I use 10 bit A/D on 8 bit Pic? 12F675

    Can anyone tell me what I am doing wrong? This code just returns " 0 0 " with 3 volts on gpio.0

    DEFINE ADC_BITS 10
    DEFINE ADC_CLOCK 3
    DEFINE ADC_SAMPLEUS 50

    CMCON = 7
    ANSEL = %00000001
    ADCON0.7 = 1
    TRISIO = %00000001
    adval var word
    ADH var word
    ADL var word
    over:
    pause 1000
    ADCIN 0, adval ' Read channel 0 to adval
    Serout2 5,16488,[#adval.HighByte," ",#adval.LowByte,13]
    goto over
