How to convert the hexadecimal o/p into decimal o/p shows in the 7 segment pic18f4550

[hee]

i have meet some problem with my coding in which my ADconverter output program shows the output in 7 segmant in hexadecimal number, but i want in the decimal number...can somebody help me to check my coding how to convert the hexa to decimal output?

and my coding
#include <P18F4550.h>
void delay1s(unsigned char);

void main(void)
{
TRISB=0;
TRISAbits.TRISA0=1;
PIR1bits.ADIF=0;
PIE1bits.ADIE=1;
INTCONbits.PEIE=1;
INTCONbits.GIE=1;
ADCON0=00000001;
ADCON1=00001110;
ADCON2=10100101;
ADCON0bits.ADON=0x01;
while(1)
{
ADCON0bits.GO=1;
while(ADCON0bits.DONE==1);
PORTB=ADRESL;
delay1s(1);
}
}


void delay1s(unsigned char nsecond)
{
unsigned char x, y;
for(x=0;x<nsecond;x++) //Total delay
for(y=0;y<200;y++); //No.of loop to generate 1 second delay
}

How is it you have only 4 connections to a 7 segment display?

I don't see any code to 'check', there is no attempt to make a conversion. You need math to convert hex to decimal and a look up table to convert decimal to 7 segment then either directly run the 7 segment with 8 pins (incl dp) or use a sipo shift register like a 74hc595 to do it with 3 pins from the mcu.

I am assuming that the 7-seg displays have their own internal circuitry and accept a 4-bit input to display 0 - F.

For what you want to display (0-255) you don't have enough digits.
