Posted on February 03, 2016 at 10:44Hello, my project involves capturing the data from a MEMS microphone array. I found one article which describes, that it is possible to achieve this with a STM32F4 processors, so I would use STM32F407 discovery bo...

Posted on December 17, 2015 at 17:33Hi, Q15 fir caused me some confusion, while everyhting runs succesfully with F32 fir. Q15 fir initialization structure demands, that you pass a Q15 pointer, pointing to filter coefficients. The problem is FIR coef...

Posted on December 08, 2015 at 08:56Hello, in one of the projects my device regulary goes to standby and I need a place to buffer the data. Since the F4 series do not have so many small sectors and the program already takes over the first 4 smallest...

Posted on November 20, 2015 at 17:40Hey guys, I just need a confirmation, that I understood this correctly. To compute the orginal signals amplitude from the FFT amplitude, you have to divide the FFT specific frequency amplitude from the FFT length ...
