Hi, I am trying to design the butterworth filter using CMSIS library in cortex-M4 processor.. i know how to do it in MATLAB(and even fdatool), but i don't know anything about CMSIS library.. i saw the arm_fir_filter example and i understood it.. but my requirement is IIR filter design.. i am not getting any example code or any links how can i design a Butterworth filter using CMSIS library..
I know we don't have Butterworth API in CMSIS-DSP, so which one i should use Biquad Cascade IIR Filters Using a Direct Form II Transposed Structure or Infinite Impulse Response (IIR) Lattice Filters
please can anyone help me out to solve this problem?
