Proteus – PIC 18F Blink a LED

Your first Proteus PIC project – Blink a LED on port RD2 of a 18F4620

This is your first PIC project ever, blink a LED, yes, I know…

But it’s a great way to learn!

#pragma config OSC=INTIO67 // use internal oscillator – Depending on your PIC this could be: #pragma config FOSC = INTOSC_EC
#pragma config LVP = OFF // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)
