i also have a problem on my atmega32. im trying to fix my bad fuse. can you make the circuit diagram the way you fix your avr?

Regards
Darwin

generally useful as well.

I’am programming the atmega32 and I have a problem with the FUSES. I intented to program the MCU with a crystal of 8Mhz. I program the FUSES: Hfuse>0xC9 and Lfuse>FF. Nothing happened. Afther I program the Fuses: Hfuse>0xD9 and Lfuse>FF. Nothing happened.
The MCU programmer is AVRISP.
I don’t understand. Would you mind explaining that further?

The system where I have programming is LCD and USART.
The fuses got from the datasheet atmega32.

Thanks.

in extreme burner AVR software.I tried to set fuse bits such that it uses an external crystal clock source. i.e. set high byte 89 and low byte FF.
but after programming when i tried to read contents the software shows error like this
“Powering on failed
cannot able to communicate with target chip…”
and i does not changed SPIEN value,
please tell how to recover the chip.
thanks in advance.
