[req]interface dc voltage to pc

hi a want to interface small varying dc voltage to conputer by and port and i want to use it in visual basic to do further action .. my varying voltage say 0 to 5 v or 0 to 10v dc ,,.. can anybody help me for this using any microcon. like pic... thanx in advance

What you are looking for:

thanx for helping i want the folling

how to use PIC ADC with source and ckt diagram( 1)PIC ADC)


2)interfacing a PIC to PC

the 1st link you given is right but its too old no links in that thread working... i want only single channel ..

and second link is also nice,, plz help further .. thanx again

finally i got this project

**broken link removed**


but when i trying to compile the folling program to CCS C compiler it giving error


#include <16F876.h>
#DEVICE ADC=10
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232 (baud=57600,rcv=PIN_C7, xmit=PIN_C6)

float value;
float temp;
float volt;

void main()
{

//Initialize and Configure ADC

setup_adc_ports( ALL_ANALOG );
setup_adc(ADC_CLOCK_INTERNAL );
set_adc_channel( 0 );

while(1)
{

//1 Sec Delay
delay_ms(1000);

//Read ADC Value
value = read_adc();

//Convert Value into Volts
volt = (value / 1023) * 5;

//Convert Volts into Temperature
temp = volt * 100;

//Send data to PC
printf(“Temperature: %.1f\n\r”,temp);

}

}

plz help

??

what error are you getting ?
