Hi, im sucks in programming, i need help in wiegand rfid c programming in mplab c18 complier. Im using PIC18f4520 and c language . I've changed all the configuration of PIC16 to PIC18, why is the code not working? How to read the tag number and display it on LCD? Do i need to use any wiegand to uart converter or i can just get my results through the PIC port(connect the data0 and data1 to RC1 and RC2)? Or i must get my result through the RS232? PLease help. (

Are you sure you upgrade the code correctly? A single wrong configuration bit might cause nothing to work even the rest of program is correct.

for pic16f876A in assembly language is __config(0x3F32)
for pic18f4520 in C language is
#pragma config OSC = RCIO6
#pragma config FCMEN = OFF
#pragma config IESO = OFF
#pragma config PWRT = OFF
#pragma config BOREN = SBORDIS
#pragma config BORV = 0
#pragma config WDT = ON
#pragma config CCP2MX = PORTC
#pragma config PBADEN = ON
#pragma config LPT1OSC = OFF
#pragma config MCLRE = ON
#pragma config STVREN = ON
#pragma config LVP = ON

is it correct??

I wonder how you translate it?

This is my configuration. I'm lazy, that's why I'm doing this and auto select PIC configuration.

Thank you very much!
