the result of FFT question
2*pi*0*n = 0, 0/(N + pi) = 0, 5*cos(0) = 5 OR, if you meant... 2*pi*0*n = 0, (0/N) + pi) = pi, 5*cos(pi) = -5 a, b or c you say?

16bit/16bit division by using assembly
You don't mention if the numbers are signed or unsigned so I expect hey are unsigned. You also want a non-integer result. I would probably implement a 32-bit by 32-bit divide...

PWM Audio
'Magic Numbers' are a pain to support. Just imagine it was someone elses code you had to try and figure out the intent. That's just what this code will look like to you after a...

Mystery Signatures, Cant Program ATmega88V parts
As I mention in your other thread, 1E 93 06 is an ATMega8515 by rights, but then it should have 40 pins.

ATMEGA88V - Clock running at 1/8 speed???
According to my search for signature 1E 93 06, you have an ATMega8515, not an ATMega88. I guess you'd notice if you had 40 pins instead of 28 though...

ATMEGA88V - Clock running at 1/8 speed???
Can you post the signature? It may be it isn't an '88 after all (suppliers have had parts mis-filed before), can you read the part number on the chip? An ATMega8, for instance,...

Debugging questions (mostly)
I enquired as to the per thousand cost of having SMD ATMega168s pre-programmed by Atmel, suffice it to say it ain't happening! The USB product I just completed, currently being...

attiny2313 problem
Hi Lee, Well, I am glad to see that you upper-cased the macro name, that at least gives the reader a strong clue that they will be looking in vain for the 'function'. I DO use...
