To use the latest CMSIS and DSP libraries (v5.9.0 and v1.15.0) in your project, download them from the official ARM repositories on GitHub.
Visit the CMSIS repository (github. com/ARM-software/CMSIS) and the DSP library repository (github. om/ARM-software/CMSIS-DSP), and fetch the latest versions.
Then, integrate these libraries into your project by including the necessary headers and source files, and update your build system (e.g., Makefile or CMake) to link against them.
Ensure your development toolchain is compatible, and adapt your code to leverage any new functions or improvements introduced in the updated libraries.
