Hi,

I ran cla_adc_fir code for 5 filter coefficients , now am trying that code for 16 filter cofficients just by modifying the filter length to 15, adding 16 filter co-efficients to the code and am getting filtered output as shown in below attached file.can u please tell what are the further modifications i need to do in my code?

Regards,

Ashwin,

This will require some debug. Assuming the coefficients have been defined correctly, I would suggest stepping through the code to determine where things are going wrong.

Ashwin,

I hope you also realize that the assembly implementation of the filter in fir32.asm is hardcoded to 5 filter coefficients. So you will need to make changes there as well.

Thanks,
Sira

Sira,

I have made the changes in the code accordingly in the assembly language and in the main c code and in the .h file also .
I feel stepping into the code will give a idea of where i am going wrong .
