PIC 18F4550 code on microC pro, simulation on Proteus not working!
Hello every one, I have been facing a problem regarding my code for PIC for quite a few days now,
I am new to PIC programming in microC since i have only worked on 8051 microcontrollers and keil,
I would really appreciate it if some one can kindly tell me what am I doing wrong in the code given below!
// code to switch on LED when push button at pin RA0 is pressed and off when it is released
sbit LED at RB0_bit;
sbit LED_Direction at TRISB0_bit;
sbit SW at RA0_bit;
sbit SW_Direction at TRISA0_bit;
CMCON = 0x07;
LED_Direction = 0; // setting pin B0 as output
SW_Direction= 1 ; // setting pin A0 as input
TRISD= 0; // setting port D as output
PORTD = 0xff;
PORTD = 0x0f;
its a simple code to switch on and Off an LED when button is pressed but its not simulating in proteus!
thank you in advance
here is the proteus design
