Hello, I have a problem with a project and the creator has suggested that this might a problem with the fuses.
His response is shown below.
Could you please tell me how can I set the fuses?


at the first look I thik this could be a fuse problem. Without setting
the fuses, the controller will run mostly at 8 MHz RC oscillator
divided by 8 (1 MHz). The correct settings will be found unfortunately
only at the documentation of the 0.35 version:

ATMega 88:
- ----------
LOW 0xe6
HIGH 0xd4
 

You use external oscillator for microcontroller ?

Atmel AVR® Fuse Calculator
https://www.engbedded.com/fusecalc

Yes it uses an external 16MHz crystal.
I have just downloaded winavr, maybe I could set the fuses there?

But I do not know how to translate these hex codes into settings or where do I have to set them.
Thanks for your help
 

You can try:

Low 0xEE
High 0xDF
Extended 0xF9

Can you suggest me a procedure to do it?

a simple homemade programmer and a suitable software? Things are so confusing...
 

Yes Atmel make there some mess in comparison with Microchip.

What programmer you have? Check in programmer software what parameters you have for setting fuse.
 

I have GQ-4X which supports atmega88 but I do not see anywhere to set the fuses in the software.
I think winavr includes avrdude, and you can set the fuses there. but can I make a simple programmer to cooperate with avrdude?
