how to assign digatal and analogue pic pin

[esweya]

hi there! i have a problem of assigning pic16F876A pins as digital and analogue input. am using digital and analogue sensor at the same time.

 

[yuvko]

are you using both on the same i/o pin?

eswya, please, give us more information about your problem, in order we can try helping you.

Am actually using ds1820 digital temperature sensor and piezo-electric thin film as a pressure sensor which gives analogue output to the microcontroller. am using RA5 as a digital input for ds1820 and RA0 for analogue input for piezo-electric sensor. I have failed to assign those pins to their respective input.

 

[yuvko]

what setting (PIC registers) are you currently using?

 

[esweya]

Am currently using register A, pic 16F876A

i think you are connecting analog sensor in RA0 and RA5 want to be digital. right?
do this
ADCON1 = 0b10000001;
ADCON2 = 0b01000010;
//then for conversion set channel first
CHS0 = 0;
CHS1 = 0;
CHS2 = 0;
//set go/down pin to one
ADGO/*depending on compiler the registor value may be different*/ = 1;
//wait for conversion
while(ADGO == 1);
//take the value
ADC0 = ADRESH;
// give a delay for 20 milliseconds
