This is a sample code showing a minimal configuration of a PIC32MX795F512L to get on RA1 a high level (logical 1) of a duration of one cycle at 80MIPS. The aim is to validate a simple design by verifying :

To do that, two files have to be added to a blank project in MPLABX using C32 or XC32 compilers :

#include "HardwareProfile.h"

void CPUInit(void) {
	SYSTEMConfigPerformance(SYS_FREQ);

	DDPCONbits.JTAGEN = 0;		// Disable JTAG
	DDPCONbits.TROEN = 0;		// Disable trace

	PORTSetPinsDigitalOut(IOPORT_A,BIT_1);
}	

int main(void) {

	CPUInit();

	while(1) {
		mPORTASetBits(BIT_1);
		mPORTAClearBits(BIT_1);
	}	

	return 0;
}

#include <plib.h>
