i need to know about the basic components to run pic18f458 in proteus 7...kindly help me plz...
 

The basic components required to make a PIC operate are Vcc,GND,crystal oscillators & bypass capacitors. You know that Vcc & GND are the major necessities of a device to operate. Crystal oscillators are provided to get cyclic clocks to the PIC.The capacitors are provided in order to eliminate noise i.e AC signals from the circuit.

Jerin. :)

Do ground the pin MCLR for getting RESET functionality.

Hi,

You just need to connect Pin1 Mclre with a 10k resistor to Positive.

If you use an internal osciilator then that is set in your code, if you use an external osc then you right click on the chip to open Edit Properties where you specify the crystal frequency and also point it to the .hex program file to use.

You do not connect any crystals or power connections as these are automatically assumed by Proteus.
 

Hi,

A simple flashing led example attached.

most PICs can run on internal RC clocks and can have their MCLR disabled so that you don't need anything to get those chips running.
