Some easy questions about AVRs
It depends on how much you're prepared to fight obstacles. I'm doing my n-th project with AVR's and all I have is self-made parallel port programmer, like "ponyprog-stk-200". If...

Some easy questions about AVRs
1) SPI is primarily intended for communication between chips on one board. Rarely across several boards in one system. It's a fully synchronous interface, with dedicated master...

64-bit division, C/asm mix
Brian, thanks a lot for this. Your algorithm looks excellent, and the ideas you use make me feel sorry that I haven't thought of that myself. So far I'm satisfied with what I have...

RF communication
It disables the RESET pin, thus rendering the mega8 impossible to program in-system. Which is 100% equal to killing it. I'm not using any parallel programer and I would need a...

RF communication
Yes, indeed, nice and dear mega8, whose RSTDSBL fuse bit is so brittle! I'm still curious about the differences. Take this module: For example...

Atmega8 PS/2 keyboard problem - double reset?
Hmm, I use code like this with avr-gcc (this is for USART, but the declaration style is what's important): void SIG_USART0_RECV( void ) __attribute__ ( ( signal ) ); void...

ADC and Accelerometer
If it's not too late, why not use MMA6260Q accelerometer (Freescale)? The cost is lower, if I remember correctly, +/-1.5G and you get nearly rail-to-rail analog output. The only...
