Need something to generate an audible alert with ATmega128
@Neil: that is true, the one I used could eat 50mA and if you don't restrain it I think it could easily eat a whole hundred without choking on it. I used a resistor to limit the...

Design of custom LCD glass
Quote:the actual design is almost incidental! That explains why all custom VFD's in car radios and the such look so apocalyptically awful :D

RF communication
From what I've found, a typical Aurel OOK transciever module can be used as half-duplex PHY for USART. That is, no additional firmware, except for properly handling of duplexing,...

@daqq: wow, thanks for pointing the Aurel out! Looks very nice and cheap. I even found a local distributor. Do you have any experience with them?

64-bit division, C/asm mix
Thanks for the compliment. But the code, except for C-embedding and some initial values is not mine. The original is linked in my original posting. That explains its compactness...

64-bit division, C/asm mix
Thanks Jim! I had no idea about 256 bytes of ram, that's just awful! I just checked and turns out that simple ++ and << operations take awful lot of funny wrongdoing.

AVR - wiki ? A good idea?
Quote:this has to be the _slowest_ loading webpage I have ever been to AVRFreaks must consider using something faster than ATmega's for their servers ;)

Help! Can i youse the UART and the 8 pins on the same port?
Not sure which ATmega we're talking about here, but I've yet to find one where you can't. So the answer is: yes, of course, you can use other pins on PORTD for I/O. Just make sure...

AVR - wiki ? A good idea?
I love this site more than anything on the internet. But when it comes to digging up information, I really prefer Wiki. It's pretty volatile: there is info, or there is no info,...

There are also "active buzzers", they only need DC voltage and they generate a tone on their own. If all you need is beep beep beep, they're the best.
