you probably talked about this before but I couldnt find it in the forum, how you conver the hex data from the ADC into dec numbers,,, instead of ff I want to get 255
| Code: | #include <16F887.h>
#FUSES NOWDT
#FUSES NOMCLR
#FUSES NOCPD
#FUSES NOBROWNOUT
#FUSES XT
#use delay(clock=4000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8)
/////////////////////////////////////////////////////////////////////////////////
void main() {
int pot_board;
setup_adc( ADC_CLOCK_INTERNAL ); //sets up the adc
setup_adc_ports( ALL_ANALOG );
while(true) {
set_adc_channel(0); // data from port A0 ( pot from board )
delay_us(50);
pot_board=read_adc();
printf("%2x\r", pot_board);
}

The format of the numbers is all in how you print them. You use the statement | Code: | | printf("%2x\r", pot_board); |
Look at the other options for printf.

Change your:
printf("%2x\r", pot_board);
by:
printf("%2d\r", pot_board);
And if you want to have separate variables for the 100's, 10's and units, try this code:
| Code: |
int8 dec_2,dec_1,dec_0;
dec_2=pot_board/100;
dec_1=(pot_board/10)%10;
dec_0=pot_board%10;
