Hello...
I guess it had to happen... I reprogrammed the fuse bits of my ATmega32, and now it doesn't work anymore and Avrdude can't connect to it anymore... :-/ I have been using it for two months on the internal 1MHz RC oscillator, but now I need to use it at full speed, so I connected a 16Mhz crystal and a couple 22pF capacitors, and read the data sheet to figure out the fuse bits. But apparently I somehow screwed up, the chip doesn't run anymore (all I can see on the XTAL pins is a constant 2+ Volts). The best I could figure out for a 16MHz crystal clock source is: CKOPT = 0 SU = 11 CKSEL 3:0 = 1111 If anyone runs successfully an ATmega32 with a 16MHz crystal, what settings did you use ? According to the datasheet, I can reprogram the fuse bits in parallel mode, or JTAG, but sadly I don't have a parallel programmer, I only use SPI with a DIY parallel port cable and avrdude. And as for JTAG... it won't work as I happened to disable it last week, as I needed to use PORTC... So I would be very grateful if someone could tell me what's wrong in my clock bits, and also, if anyone in France or nearby (Joerg ?! ;-), has the facility to get the fuses back with parallel mode programming, I would be soooo happy. I mean, the chip costs 15 Euros including VAT, so it's worth paying a little postage fee to rescue it. I have got a couple spare mega32 to keep me going in the interim.
