agaelema 39 Posted August 15, 2017 Share Posted August 15, 2017 Hi. 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 MSP432Example of use - FIR filter I hope it's useful. spirilis 1 Quote Link to post Share on other sites
spirilis 1,265 Posted August 17, 2017 Share Posted August 17, 2017 Hi- quick question, do you have any software you like for designing filters? (e.g. FIR or IIR coefficients) I may be dabbling into MSP432 DSP work soon... Quote Link to post Share on other sites
agaelema 39 Posted August 17, 2017 Author Share Posted August 17, 2017 Hi @spirilis I'm not a specialist, but traditionally designers use tools like Matlab to select coefficients and test. If I'm not wrong, the CMSIS coefficients were calculated using matlab (providing the code). Octave is a free tool with same syntax and similar functions. This link show an example using matlab/octave https://www.allaboutcircuits.com/technical-articles/design-of-fir-filters-design-octave-matlab/ https://www.allaboutcircuits.com/technical-articles/practical-fir-filter-design-part-2-implement-filter/ Bellow there are some links to tools (but I have not tested) http://t-filter.engineerjs.com/ http://engineerjs.com/?sidebar=docs/iir.html http://iowahills.com/Index.html spirilis 1 Quote Link to post Share on other sites
