I am using the F28335 chip. I looked for iir and fir filters and found some for the C2000 but they are written for integer math. My questions are:

1) Is there a library for the C2000 chips with floating point support?

2) If not and I need to use the integer versions, for iir32, do I need to scale the input to Q15 (ie x 32768) before feeding it to the filter function?

3) Why isn't there a 32 bit version of the FIR? Or is there?

Thanks
