Because the LPC55S69 has PowerQuad, in SDK example code, the FFT/FIR/IIR and the other DSP function are implemented by the Powerquad module instead of the Cortex-CM33 core.
This is the Powerquad example to implement the DSP function:'
But if customers want to use CMSIS-DSP to implement the DSP function based on Cortex-CM33 instead of Powerquad module, customers can not import SDK example, he has to create a new project, this is the procedures:
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.
3)as the following screenshot, after completion, you can see the CMSIS-DSP source code and library have included in the project
