[Moved]Proteus 8.1 Simulator: LED NOT FLASHING

[thandana]

Hi,

I have a simple circuit that i created on the proteus8.1 simulator and have written code to flash LED connected to the PIC16F84A device.

When i simulate, the LED is NOT flashing and NO ERRORS on the simulator. Please assist

void main() {
TRISB=0b11111101;
while (1)
{
PORTB.f1=1;
delay_ms(500);
PORTB.f1=0;
delay_ms(500);
}
}

What is ".f1" ?

Try replacing it with just the number 1, "PORTB.1" and see what happens.

In a real program you would also configure the clock source and other registers, I'm not sure if MikroC and Proteus respect that though.

Brian.

At the schematic attached, there is nothing connected to the Oscillator pins.
According to datasheet, there is no internal oscillator available for this uC in particular.

Hi,

This can be closed now. I connected the oscillator and applied 5V and now works OK. Thanks for the help.
