mikroc/proteus problem

[masab_ahmad]

Hi all,

I made a few codes on MikroC and used proteus to see the simulation. I am using a pic16f877a microcontroller. I firstly made this simple code, which didnt work in proteus:

void main()
{
TRISC = 0 ; // PORTC as outputs
PORTC = 0 ;
PWM1_Init(40000);
PWM1_Start();
while(1)
{


PWM1_Set_Duty(200);
}
}

Then I made this one, which gave me some strange waveforms( unwanted), at the CCP1 pin:

void main()
{
TRISC = 0 ; // PORTC as outputs
PORTC = 0 ;
while(1)
{
PWM1_Init(40000);
PWM1_Start();
PWM1_Set_Duty(200);
}
}


I don't understand what went wrong, the first code should have worked! I think proteus is the problem here, plz help....

Zip and upload your Proteus and MikroC files, so that one of us can examine it.

ANSEL = 0; // Configure AN pins as digital
ANSELH = 0;
C1ON_bit = 0; // Disable comparators
C2ON_bit = 0;
ANSEL AGAIN!!!

files attached, i also simulated the attached stuff on another simulator, The RealPic Simulator, and it all works perfectly on it....
