This document provides a 10 step process for making a USBASP programmer to program AVR microcontrollers. It discusses downloading the necessary software, burning the hex file to program the microcontroller, setting the fuses using AVR-Burn-O-Mat software, and connecting the circuit components according to the provided diagram. The goal is to create an inexpensive alternative for programming AVR chips using a USBASP circuit.

1. USB-ASP 10 EASY STEPS TO MAKE IT

2. WHY I MADE THIS? I made this project(usbasp) as secondary project during my main final year project (dtmf + computer controlled project). During my main final year project I used avr atmega8 microcontroller. Although I bought one burner from market , but I decided to make it of my own one time investment and as an effective alternative. I am sharing that process with all of you.

3. SOFTWARES WINAVR ( www.thoughtcrackers.blogspot.com ) AVR STUDIO (FROM ATMEL SITE) AVR-BURN-O-MAT ( www.thoughtcrackers.blogspot.com ) GO TO http://www.fischl.de FOR INFORMATION ON USBASP.

4. You will need one extra burner in this method for burning “.Hex” in to microcontroller ( µ c) . FIRST : Burn hex file in to µ c . there are two hex files choose any one According to your µ c (Atmega8 or atmega48). SECOND : Burn fuses in to µ c. I am showing method for atmega8 using avr-burn-o-mat. Some people may use extreme burner or any other software for burning.

5. Download zip or rar files requared From http://www.fischl.de . Extract them through win-rar or zip. Read “readme.Txt” File carefully, you will see Under firm ware section. Important

6. HOW TO USE AVR-BURN-O-MAT APPLY APPROPIAE SETTINS 1 2 3

7. FUSE SETTINGS SET CRYSTAL OPTIONS THE EFFECT CAN SEEN IN WINDOW BELOW PREES WRITE FUSE 1 2 3

8. CIRCUIT DIAGRAM Optional **D1 & D2 are Used for safety From high voltage. Optional ** short circuit protection

9. Now make wire connections on pcb , using circuit diagram( I am going to give you circuit diagram which was used by me in my project). During my project I had removed all optional components from circuit shown. After applying all components ; Apply µ c (In which you have burnt .Hex)on circuit.
