Programming AVR micro controller using Atmel Studio 7

In this blog, we will learn how to upload hex file using Atmel Studio. Atmel Studio is used for programming ATtiny, ATmega and AVR32 mirocontrollers. You can download atmel studio from:

Download Atmel Studio

Open Atmel Sudio from windows start menu:

File > New Project >  GCC C executable project

In device selection, choose Atmega8a

In main.c write down the following program for toggling PORTD

#define F_CPU 8000000
#include<avr/io.h>
#include<util/delay.h>

int main(void)
{
	DDRD = 0xff;  // set portd as output
    while (1) 
    {
		PORTD = ~PORTD; // toggle PORTD bits
		_delay_ms(500); // delay of 500 ms
    }
}

Follow the steps as mentioned above n the screenshot. 

Once the code is successfully compiled, we are ready for the next step i.e. uploading the program to the target board.

Go to: Tools > External Tools > 

In arguments type this:

avrdude -c usbasp -p atmega8 -U flash:w:$(ProjectDir)Debug\$(TargetName).hex:i

since we are using atmega8.

Provide the path of avrdude in command. You can input USBasp in Title

Make connections as follows:

USBasp programmer                                                Atmega 8 target board

Vcc       ===========================>      Pin 7,20,21 

GND     ===========================>      Pin 8,22 

MOSI    ===========================>      Pin 11 

MISO    ===========================>      Pin 12 

SCK      ===========================>      Pin 13 

RST       ===========================>      Pin 1 

Now click on: Tools > USBasp

And voila your mcu is flashed!!
