it is very difficult to bootload Atmega chips when you don't have proper knowledge about device signature ! each chips are associated with its own Signature.at the beginning I found very difficult in uploading bootloader file to Atmega 328pu and Atmega 328p-pu , although their are many different methods are already available in Internet ,it is tedious job for me to follow those methods so I found one easy method since it is similar method for all the the chips ..!! so letz get started
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Components Required !!
1) arduino uno
2) avr programmer (200inr)
3) Atmega 328pu/328p-pu...here P indicates Picopower !!
4) few male to female jumpers
5) AVRDUDESS 2.4
Step 2: Wiring Arduino Uno to AvR Programmer
Arduino ICSP has 6pin and Avr programmer Has 10pin in it , now you have to carefully connect the pin as per the 2nd diagram
arduino (6pin)----------- 10pin on AvR
GND(6)------------GND(4,6,8,10)use any pin
Step 3: Downloading AVRDUDESS and Arduino 1.0.5 Software
select programmer on top corner Here
select "Any usbasp clone with correct VID/PID "
and Press "DETECT" on the Right hand side !!
their you will get ...the MCU which you have connected on the arduino uno..
then on "Flash" option select the hex file from arduino software
and check Write option and then click Go
wait for few seconds
now your Atmega IC has successfully programmed ...!!
you can use this procedure for other ic also ..
Thank you, if you have any doubt please leave a message at the comment section ! I will reply within a day ..
