Introduction: ARDUINO CLONE With ATMEGA328-PU Non P

A way to bootload Atmega328-PU non pico power with Arduino 1.0.6 ISP.

Step 1: The Beginning

Picture of The Beginning

Last week I decided to make a classic Arduino clone with an ATMEGA328P-PU. I seemed to be so easy and quick but a very bad surprise for me : I odered the cheaper ATMEGA328-PU (non P!!) that is to say: non pico power.

The difference : this IC needs a bit more energy and IS NOT COMPATIBLE with the arduino ISP bootloader (see the wrong signature). So I was a bit disapointed.

I looked on the net for a method to bootload this kind of circuit: a lot of methods found but none of them would run with Arduino 1.0.6. So I tested one of mine: a sort of mix beetween all this tricks. I will give it to you now...

Step 2: The Schematic and the Bootloader to Use:

Picture of The Schematic and the Bootloader to Use:

You can find it easily on :

https://www.arduino.cc/en/Tutorial/ArduinoISP

I use a prototype board to connect all the cables on the photo (components on the top of the board are decorative).

Then you have to follow these steps:

1-download in your arduino the famous example "arduinoISP", then close Arduino 1.0.6

2-backup the arduino/hardware/tools/etc/avrdude.conf and do the following change (at line 8080 for me in notepad++) :

I give you the initial avrdude.conf and the modified file in 2 archives.

3-run ARDUINO 1.0.6

4-select the board Arduino Duemilanove or Diecemilia

5-select the good pprocessor: Atmega328

6-select Arduino s ISP

7-burn the bootload

8-shut off ARDUINO 1.0.6, replace avrdude modified by the original file you back up.

9-now you have to change the file arduino/hardware/arduino/avr/boards.txt to make appear the new board name with this kind of circuit. I called it: Arduino Uno w/ ATmega328 (non-P)

The text you have to insert in it:

##############################################################

uno328.name=Arduino Uno w/ ATmega328 (non-P)

uno328.upload.tool=avrdude

uno328.upload.protocol=arduino

uno328.upload.maximum_size=32256

uno328.upload.speed=115200

uno328.bootloader.low_fuses=0xff

uno328.bootloader.high_fuses=0xde

uno328.bootloader.extended_fuses=0x05

uno328.bootloader.path=optiboot

uno328.bootloader.file=optiboot_atmega328.hex

uno328.bootloader.unlock_bits=0x3F

uno328.bootloader.lock_bits=0x0F

uno328.build.mcu=atmega328

uno328.build.f_cpu=16000000L

uno328.build.core=arduino

uno328.build.variant=standard

Save it.

I give the file in the supplied archive.

10-Now you can use ARDUINO 1.0.6 to programme either UNO board with Arduino uno card or the atmega328-pu/ 16MHz with Arduino Uno w/ ATmega328 (non-P) card with USBasp in my example.


Step 3: The Schematic of an Example of the Clone: Made of Atmega328-PU Non P! of Course

Picture of The Schematic of an Example of the Clone:  Made of Atmega328-PU Non P! of Course

This card is used on one of my projects : the 6 axis robot. It needs a powerfull 5V DC supply voltage.

On the picture I mounted an ETHERNET shield easily on the top of the clone and you can see the USBasp to download the appropriate program.

Step 4: Conclusion:

I hope it will help some people who buy the wrong but cheapest atmega328-PU non P!

Thanks to all stimulating tutorial all over the net.

Happy instructable!!!!

what about the pin 22 it is not shown in schematic

manu4371 (author)MohammadU182017-10-25

coz pin 22 is internally linked to the ground and not shown on PROTEUS.

DonCesare (author)2016-09-24

Awesome ible. I ha the same issue with an Atmega PU. Now I know what to do thanks to you. Thank you so much!

manu4371 (author)DonCesare2016-09-24

Thanks for your support. It really works for me! I hope the same for desapointed (may be) you!

Happy instructables!!
