In this tutorial we will see how to setup a Mplabx project to generate .hex file for Pic16f877a

MPLABx Setup Steps

Step1: Open the MPLABx software and select the New project from File Menu as shown below.

Step2: Select the Standalone option for the project.

Step3: Choose the Controller(PIC16f877A) from the device drop down.

Step4: Select the required programmer. In this case it is Pickit2.

Step5: Choose the xC8/Hitech compiler which ever is installed.

Step6: Provide the project name and project location.

Step7: Now the required project is created. Create a new .c/main.c to write the code.

Step8: Save the file with C extension.

Step9: Type the code or Copy paste the below code snippet and save it

	#include <lpc17xx.h>

	void delay_ms(unsigned int ms)
	{
	unsigned int i,j;

	for(i=0;i<ms;i++)
	for(j=0;j<20000;j++);
	}

	/* start the main program */
	int main()
	{
	SystemInit(); //Clock and PLL configuration
	LPC_PINCON->PINSEL4 = 0x000000; //Configure the PORT2 Pins as GPIO;
	LPC_GPIO2->FIODIR = 0xffffffff; //Configure the PORT2 pins as OUTPUT;

	while(1)
	{
	LPC_GPIO2->FIOSET = 0xffffffff; // Make all the Port pins as high
	delay_ms(100);

	LPC_GPIO2->FIOCLR = 0xffffffff; // Make all the Port pins as low
	delay_ms(100);
	}
	}

Step10: Build the project and fix the compiler errors/warnings if any.

Step11: Code is compiled with no errors. The .hex file is generated.

Step11: Check the project folder for generated .hex file.

After generating the .hex file check the below tutorials for uploading it using Pickit2 or Ds30 Software.
