Hello,

To compare the performance of mathematical processing between CM33 and PowerQuad,

I'm looking for CMSIS-DSP precompiled library file(.a) can be used in MCUXpresso for LPC55S69EVK,

But I can't find it anywhere. It is not included in SDK generated by MCUbuilder site.

I need to build the library from CMSIS DSP source code?

Regards,

Norihiro Michigami

Hi,

If you want to call the CMSIS-DSP function based on CM33 based on LPC5569, you can not import an SDK example, but you can follow up the procedure, the condition is that you have dragged the LPC55S69 SDK package to the Installed SDKs:

1)Create a new project by clicking New->Create a new C/C++ Project

2)select the processor like LPC55S69

3)In the following menu,click CMSIS Driver, and check the CMSIS_DSP_Library and CMSIS_DSP_Library_Source

You have to click the Driver which can select your peripherals driver you will use. You can

3)as the following screenshot, after completion, you can see the CMSIS-DSP source code and library

Hope it can help you
