TLDR
Fast IIR filtering on ARM Cortex-M with CMSIS-DSP and GNU Octave and GCC Octave. iir-designer-cmsis-dsp is available with examples on GitHub. The code is mostly boilerplate, and you just need to provide an input array of floats (pSrc) and a buffer for the filtered signal (pDst) and their length (blockSize) to run the code. Let us know if you find it useful, we would love to know what people are using it for!via the TL;DR App
