. But no, I cannot recommend any crystal for use in the low-drive mode. :-P Unfortuntely only available in german, but still very good: Das Quarzkochbuch http://www.qsl.net/dk1ag/buch.html Regards, Clemens Koller __ RD Imaging Devices Anagramm GmbH Rupert-Mayer-Straße

mustn't drive any other or any big load with the oscillator and have a low power (uWatt) capable crystal. (BTW: I'm using the ATMega168 right now). Regards, -- Clemens Koller __ RD Imaging Devices Anagramm GmbH Rupert-Mayer-Straße 45/1 Linhof Werksgelände D-81379 München

Re: [avr-chat] double check connections

check connections and try again, or use -F to override this check. ~ Smells really like a toasted AVR. Just replace the AVR and give it another try. Regards, Clemens Koller __ RD Imaging Devices Anagramm GmbH Rupert-Mayer-Straße

with only about 3.1Volts and some 100Ohms serial resistance. This isn't really a problem, if your circuits are able to deal with it. Regards, -- Clemens Koller __ RD Imaging Devices Anagramm GmbH Rupert-Mayer-Straße 45/1 Linhof Werksgelände D-81379 München Tel.089-741518

Re: [avr-chat] how to program surface-mount micros?

Re: [avr-chat] TCP/IP : practical guide to implementing ? (LONG post...)

/IP implementations. Of course, it's necessary to know what happens inside of the code if something goes wrong. Your best friend is a good debugger and know-how to use it. But I would first give it a try and starting from the top-level. Download the code and give it a try. Good luck, -- Clemens
