ASM program: External interrupts won't work in ATMega8 And as pointed out in #4 inc and dec changes flags so it can't be de done this way.
If you are new to the AVR, I will suggest that you first get it to work in C (and I...
LDI variable,' ' first it's r16 to r31 you can use LDI on.
I have only looked shortly at it but it looks like it's so they get " 345" instead of "00345"

Alternatives to timer interupt I'm confused in #12 you wrote :
the only thing the Xmega needs to do is read the adc and apply the filter then put it on the dac.
That sounds like one analog input and one analog...
Alternatives to timer interupt No that is not what Jim mean !
If you have a ISR then just put the code there!
the wait while should be on the timer overflow bit. (but not with timer ISR bit...

Variable to register, inline assembly You really need to tell what you want, the compiler don't really like that change the 8 top registers unless you directly want to 'talk' to the compiler.
It sounds a bit...

First it works you must have an error! Are you sure that you don't have the bootloader enabled or something like that. add: Some chips the ISR clr the active...
perhaps the driver of the slave need to have the same delay line. Just short have you remembered to give them the same ground ?
my small input: Can you get the master to make 2 stop bit's ? (perhaps that can help depending of what the real problem is). Delay the signal from slave (and only...
I just had a quick look at you code and if you just push R16 before LDI R16,xx and after SPM pop it back it should work.
Atmel never took the job to make datasheets serious so they had a lot of errors. And unfortunately it look's like Microchip don't care either. ...
