STK500 and the ATtiny 24,44,84
Quote:** -- Check out Mega406. IIRC there is a Tiny that doesn't have "serial program downloading" either.The ATtiny28 falls into this category.

ATtiny 28 C code Non-RAM memory
Most compiler producers don't think it's worth it. Obviously, some people think it's worth it, hence the link in the FAQ describing how to do it. Personally, for a micro as small...

You could build your own adapter board. All you need is a DIP socket and a 6 pin header to connect back to the ISP header on the STK500.

Multi-Slave RS-232
I would expect two diodes could make this work. Although, I think you have the polarity of them reversed in your diagram. Why don't you just try it and find out? I think Cliff's...

[Atmega16]Does IN/OUT instruction run in 1 cycle?
IN and OUT are 1 cycle each. Your code example also has a while loop which would be an RJMP. RJMP is 2 cycles. So two OUTs and an RJMP is a total of 4 cycles per iteration.

avr-gcc 4.2.2 generating incorrect assembly
Scratch that last comment... I just realized I didn't rename all instances of "val" in the function. When I do, the problem still occurs... I did say reusing global variables...

avr-gcc 4.2.2 generating incorrect assembly
I tried renaming the local variable "val" in the inline function and the problem appears to go away. While it should work as is, this may be a good work around for you for now....

avr-gcc 4.2.2 generating incorrect assembly
Maybe the compiler is getting confused because you have a module wide variable and a local variable with the same name? The function in question is also a little strange: long...

UART oddity absolutely baffling
Perhaps there is a problem with the stack setup? This could cause the function call (or more likely the return) to fail.
