    Hi, I'm working in this library with some useful DSP and math functions (ideally focusing on embedded systems). Currently it's in the initial version with few functions, but I hope to add more in the next update. I prefered to use some structs to save parameters and use just one function to various instances of filters (very versatile). Functions - High Pass Filter (Single pole): Float, fixed and fixed extended version (with more bits to fractional part) - Low Pass Filter (Single Pole): Float, fixed, fixed extended and fixed fast (with some limitations related to cuttof frequency, but more efficienty. - RMS value: calculate RMS value of an array or sample by sample. Currently using square root function of math.h, but in the next update I will add a optimized version. I hope this can be useful. Feel free to test, share and contribute with this project.

    Hi everyone, I updated the library adding some functions: - to easily generate sine waves in a array and iteratively - goertzel dft using array data or sample by sample (very interesting because not need an array) Enjoy it Github: https://github.com/agaelema/DSP_and_Math

    Has anyone seen the : Mini-M4 for Tiva-C https://download.mikroe.com/documents/starter-boards/mini/tiva/mini-m4-tiva-manual-v100.pdf Would it be safe to assume that it could run energia? Best, C.
