Pic18f4520 MPLABx Setup

In this tutorial we will see how to setup a Mplabx project to generate .hex file for Pic18f4520

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(Pic18f4520) 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 <pic16f877a.h>
	void DELAY_ms(unsigned int ms_Count)
	{
	unsigned int i,j;
	for(i=0;i<ms_Count;i++)
	{
	for(j=0;j<1000;j++);
	}
	}
	int main()
	{
	/* Configure all the ports as Output */
	TRISA = 0x00;
	TRISB = 0x00;
	TRISC = 0x00;
	TRISD = 0x00;
	while(1)
	{
	PORTA = 0xff; /* Turn ON all the leds connected to Ports */
	PORTB = 0xff;
	PORTC = 0xff;
	PORTD = 0xff;
	DELAY_ms(100);
	PORTA = 0x00; /* Turn OFF all the leds connected to Ports */
	PORTB = 0x00;
	PORTC = 0x00;
	PORTD = 0x00;
	DELAY_ms(100);
	}
	return (0);
	}

Step10: Flash setup : Board comes with bootloader, we need to make the following setup otherwise generated hex file may overwrite the bootloader.

Step11: Build the project and fix the compiler errors/warnings if any.

Step12: Code is compiled with no errors. The .hex file is generated.

Step13: Check the project folder for generated .hex file.

Uploading the Hex file

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