[MPC5748G] FIR filter design question

jzhang1 — Thu, 28 May 2020 21:54:12 GMT

Hi,

Does S32 Design studio have the ready-to-use library or function for the FIR filter? Like the command in Matlab "b = firpm(n,f,a)"https://www.mathworks.com/help/signal/ref/firpm.html#d120e59899

I want to design a bandpass or low-pass FIR filter to process the real-time data from the ADC module on the board.

I appreciate your help!

Hi Junyi,

you can use FIR filter from AMMCLIB:

The library is already integrated in the S32 Design Studio:

c:\NXP\S32DS_Power_v2.1\S32DS\software\AMMCLIB_1.1.15\MPC574xG_AMMCLIB_v1.1.15\

Search for GDFLIB_FilterFIR in the documentation.

Regards,

Lukas
