Hi!
I want to implement FIR digital filter on my ATMega16, running at
8MHz. I was succeeded with input, output and C-based implementation
of the filter. It works, but too slow: troubles coming at 10 kHz of
sampling frequency, and fifth order of the filter.
Surely, assembly would help me.
But I can't make included .S90 assembly file work for me. In C code
of ATMEL example we see function declaration
extern int FIR2( struct FIR_filter *thisFilter, int newSample );
and usage:
filterOutput = FIR2((struct FIR_filter*)&filter04, filterInput);
And there is "FIR2: ..." filter function in 2nd_order_FIR.s90
What should I do (makefile, includes, etc.) to tell compiler where
to search and what to do with FIR2 function?
Thanks!
Best regards,
Kreyl
