[SOLVED] Problems with PIC16f676

[ankitvirdi4]

Hello everybody, I am new to programming and PIC controllers, I just wrote down a code to blink led in MPLAB IDE v8.91 and compiled it using HI-TECH C.the code is
#include <htc.h>
#include "delay.h"
void main()
{
TRISC=0x00;
while(1)
{
PORTC=0x00;
DelayMs(500);
PORTC=0xff;
DelayMs(500);
}
}

it Compiles ok and the project builds successfully but it doesn't simulate in proteus. I have attached the workspace and simulation file please tell me where am i wrong.

Change PORTA = 0xff ; to PORTC = 0xff; U can use MPLAB sim which is easy.

I want to simulate it in proteus. If I use 18f452 then it is working fine. And thanks, I changed it to portc and tried.It builds fine but doesnt run in proteus.

Sorry I am not expert in Proteus & i know Microchip IC very well & it's simulator etc.

Its okay Thanks.I got my error I have to keep MCLR pin high in proteus know it is working fine. I am doing a project in PIC 16f676 I am good at C bt very new to microcontrollers. I want to use ADC of of 16f676 are there any subroutines available? Or will I have to make one? How to use ADC if you can please explain I will be grateful.

Add ANSEL = 0; as the first line inside main().

These devices can be configured so the pins are analog inputs or digital I/O, they default to analog inputs when reset.

Also is MICRO C for pic a better compiler or HI-tech C??

- - - Updated - - -

ANSEL=0 will configure portA as analog or I/O I understand the channels of ADC are on PortA

My suggestion is Hi-tech is better than MICRO C
