Hi everyone, a lot of time since my last post on this forum and noticed many things has changed, in better. I want to spread (spam) my boosterpack project, Aida DSP boosterpack It's a boosterpack dedicated for audio and for now available only for TivaC. With this boosterpack you can do 24bit/192kHz pristine audio elaboration, since it has a DSP on it, so while this DSP is occupied with audio elaboration you can do a lot of things with your mcu: read audio signal envelope, manage a user interface and -why not?- a complete keyboard or a rich display, ecc. http://www.aidadsp.com Libraries are available both for Energia and Arduino, please note that I hacked wire.cpp and wire.h a bit to get things done. You can buy the board, on our store to start focus on your audio application. Suggestions and collaborations welcomed!!! Max
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.

agaelema posted a topic in Code vaultHi. In the beginning of this year I wrote two articles showing how to compile the CMSIS DSPLIB to use in MSP432 and one example of use. The sequence is very similar to used in Stellaris and Tiva line. The articles are in portuguese, but there is a embedded translator. Compiling the CMSIS DSPLIB to MSP432 Example of use - FIR filter I hope it's useful.
