hello,

I am using PIC18f4550,and below is the code...The ADC works fine for any single channel..But i am unable to read multiple channels ..

Pls help. The lower bits of the 2 channels are diplayed on the ports.I only see one channels 
reading on the PORT.

Pls help this is urgent...

void main(void) 

int adc0,adc1; 
TRISA = 0xff; // All are inputs 
TRISB = 0; // All are output
TRISD = 0;
count = 0; 

adc_open(ADC_CHN_0, ADC_FOSC_64,ADC_CFG_08A_0R, ADC_FRM_RJUST|ADC_INT_OFF);

ADCON2bits.ACQT0 = 1;//(clock derived from A/D RC oscillator)
ADCON2bits.ACQT1 = 1;
ADCON2bits.ACQT2 = 1;

adc_conv(); 

while(1) 

if (!ADCON0bits.GO) {

adc0 = adc_read(); // read value
}
adc_setchannel(ADC_CHN_1);
adc_conv();

if (!ADCON0bits.GO) {

adc1 = adc_read(); // read value
}

adc_setchannel(ADC_CHN_0);
adc_conv();

PORTB = adc1 ;
PORTD = adc0 ; 

} // End While

}
