CMSIS DSP math libraries - FFT, FIR for BlueNRG-LP

[Greg_]

Hello,

https://www.st.com/content/dam/OLM%20Email%20Marketing/2021/EMEA/Events/BlueNRG-LP/STBLEBlueNRGLPWebinarApril20V3.pdf

In page 9 of the above document STM is mentioning FFT - my question is - where can I find libraries for FFT, FIR etc. for BlueNGR-LP?

I'm trying to resolve the problem linking some external libraries and it seems to work but I'd be more confident if I could use dedicated and already tested libraries if they exist.

Regards,

Grzegorz

Thank you Piranha, I started with the below libraries

https://github.com/ARM-software/CMSIS/tree/master/CMSIS/Lib/GCC

but have nothing to share yet and still worrying if they are ok for BlueNRG-LP. That's why I asked if ST have already released any package of libraries dedictaed to BlueNRG-LP and including math transforms and filters functions. It seems they have not. I'll look closer at the newest you linked.

HI @Greg_​ ,

AS far as I know, there is nothing specific for BlueNRG-LP. This BLE SoC is based on a "standard" ARM cortexM0+, so basically you can reuse CMSIS Arm lib from ARM you already mentioned..

Hi Sebastien,

Thanks for the answer - it would be nice to see them incuded in STSW-BNRGLP-DK :)
