Use the program shown below. It works. I turned the 10K trimpot
on Pin A0 so it goes from the lower limit to the upper limit. Here is
the output. It's correct.

Here is the test program. It's running on a PicDem2-Plus board and
was compiled with PCH vs. 4.099:
| Code: |
#include <18F4431.h>
#device adc=10
#fuses HS,NOWDT,NOPROTECT,BROWNOUT,PUT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
//=================================
void main()
{
int16 result;
setup_adc_ports(sAN0);
setup_adc(ADC_CLOCK_DIV_32);
set_adc_channel(0);
delay_us(15);
while(1)
{
result = read_adc();
printf("%LX \n\r", result);
delay_ms(500);
}

Are the AVdd and AVss pins connected?
AVdd to Vdd, and AVss to Vss. |
