Hi to everybody,
I would like to know if anybody knows whether it is possible to use except for the Atnega168 also the other ones from the family? e.g. Atmega 88 or Atmega 48 - I am not sure, but also the Atmega48 has enough memory to flash the fw with the tuning function as well.
Thank you for the reply and I would like to say, that it is really cool project and working very well. MANY thanks to the author. Best regards Petr F., Prague.
Atmega 168 only?

Re: Atmega 168 only?
Well I´ve just tested it and Atmega 48 does not work with the HEX even though there is enough space for the program. It´s a pity of course, I have several atmegas 48.. but no 168.. Thank you for reply.

Re: Atmega 168 only?
Of course I did. I used the link http://www.engbedded.com/fusecalc.
As the result my Atmega48 fuses are as follows: Low DE, High: DF. but it does not work...

Re: Atmega 168 only?
Hmm. It's hard to tell if the problem is the Atmega or somewhere else in your circuit. Can you provide any more information that would help us debug the problem? Is the code doing anything at all? LCD is just blank? Any serial data?

Re: Atmega 168 only?
I am trying to follow along with this build and could not find a 168.
I ended up with an atmega328p. After editing the makefile I got it to program using the usbtiny. But No display or control for tuning. I have gone through the wiring numerous times and everything seems to be correct.
Any ideas on differences between the 168 and 328 chips?

Re: Atmega 168 only?
I'm using a 328p myself, and have no problems with it. But that's with rather different software (although with the same LCD library). The 328 is very similar to the 168 though. AFAIK, it only has more flash (32k vs 16k). so as long as the compiler does its thing, and the programmer successfully finishes, it should work.
Did you set the fuse bits on your microproc correctly though?

Re: Atmega 168 only?
Did you flash the configuration fuses with 'make fuse'?
