External Interrupt INT0
Hi monarch, That's a fair amount of code to ask for an example about. It would be easier if you could post what you have instead. No need to feel intimidated, we all have to...

need a divider command
Expanding on what Steve said: multiply by reciprocal is very fast when the divisor is constant (and shifting won't suffice). Even with today's desktop CPUs, division is still slow...

Damaged AVRISP chips
That makes sense, Steve. I've seen him hot-swap other devices, so maybe the AVRISPs too. Beginning to wish I'd said something when instead I withheld my gasp (I'm a bit anal about...

SPI (ISP) and USART
Hi Denny, Typically you burn a bootloader onto the chip early on, say in early production or on the test board when testing. You can use the test board, ISP programmer, JTAG, etc...

Damaged AVRISP chips
What's with the AVRISP anyway? Is chip failure an issue with it? I do not use one, but a friend of mine is on his third, and his company said they will not purchase any more. They...

Coercing Linker to Output Hex Formats
Privet Mikle (Pryvit if you prefer), выдающийся! Worked perfectly; absolutely no problems. I see you have tamed XLINK before, since about this the documents are not clear....

On Chip Debugging AvrStudio 4 STK500
As I recall, not much, although I don't use AVR Studio for debugging. For on-chip debugging, a JTAG is really what you need. It won't occupy the board's ports, either. I just saw...

the 'X,Y, Z' registers
Yes, since all the GP registers are mapped to SRAM addresses (though I've never tried it). The address of each register directly corresponds to its "number", and you'll have to...

Coercing Linker to Output Hex Formats
Hi pepsi, That's one I didn't think of! Unfortunately, the client needs to be able to recompile the code off-site, and then remotely upload it to the device with the AVR. In fact...

ATMEGA128 SPI Interface
Hi ruchirabajaj, You can interrupt an interrupt, but normal execution prevents it. When an interrupt is triggered on an AVR, the global interrupts flag is disabled, which in turn...

Coercing Linker to Output Hex Formats
Thanks for your quick reply, glitch. >> 1) compile the 3 pieces of code separately... Unfortunately, I can't compile all of them separately, even though ultimately they are to be...
