A/D conversion - pic18f4550

[Jack41]

Hello
I'm trying to make an A/D conversion and I am trying to adapt this code for a PIC18F4550 in MPLAB IDE, but I’m having troubles. I’m programming in C and trying to read the value of a sensor on AN0. How can I adapt this code for my needs?

#include <xc.h>
#include <stdio.h>
#include "lcd.h"
#endif

int main(void){
   
    int x;
    int v;
    char d[10];
   
  __delay_ms(2000);
   
    ADCON0=0b00000001;
    ADCON1=0b00001110;
    ADCON2=0b10011110;

   Lcd8_Config(&PORTE,&PORTD,2,1,0,7,6,5,4,3,2,1,0);
   Lcd8_Init(&PORTE,&PORTD);
   
    TRISD=0x00;
    TRISB=0x0F;
   
    __delay_ms(10);
    lcd_init();
   
    while(1)
    {
        ADCON0.GO_DONE=1;
        while(ADCON0.GODONE);
        tensaohum=((ADRESH<<8)+ ADRES1)* 4.88;
        inttostr(v,d);
        strcat(d,"mV");
        lcd8_out(2,4,d);
        delay_ms(10);
    }
}

but I’m having troubles.

Which troubles? Please explain.

How can I adapt this code for my needs?

What are your needs?

Also your ADCON2 reg will need the correct values for the sys. clock you are using if different from the original code.
