Question

Is there a Standard DSP library for STM32F030R8 ,which uses a Cortex M0 ? Where can I download it?

I transplanted the general FFT algorithm ,but it took a lot of time for the CPU to run .I wonder if I can save time by using a Standard DSP library.

I never tried a DSP lib specifically for the M0, but I'm sure there is a package for the F0 family.

I got those for F10x, F3 and F4, and all of them contain code for M0 cores.

Check the ST software download section for the F030R8, there should even be a SPL-based package. Otherwise, a Cube based.

Thank you very much.But,there is still something wrong.I downloaded the cube ide, and installed it.

I'm using the ARM CMSIS DSP libraries(libarm_cortexM0l_math.a), one of the functions I'm using is arm_rfft_q15. 

Build error: undefined reference to `arm_bitreversal_16'.The function that it is referring to is an assembly function found in the file arm_bitreversal2.s and I have made sure that file is in the source file.

Any suggestions or help would be very appreciated.

Best Regards.

Hello,

Here is STSW-STM32048 STM32F0xx standard peripherals library and there is no DSP feature for Cortex-M0. You can download and use the DSP library for any of the STM32F3/F4. You should update and add code in your project.

Within STM32CubeF0 firmware package, the files are in STM32Cube_FW_F0_V...\Drivers\CMSIS\DSP. Just ensure that your project has "Include Paths" set up properly in ../CMSIS/DSP/Include.

Best Regards,

Imen

Hi,

In STM32CubeIDE, I downloaded STM32Cube_FW_F0_V1.11.0, but there is something wrong.

I'm using libarm_cortexM0l_math, the file is in STM32Cube_FW_F0_V1.11.0\Drivers\CMSIS\Lib\GCC, one of the functions I'm using is arm_rfft_q15. 

Build error: undefined reference to `arm_bitreversal_16'.The function that it is referring to is an assembly function found in the file arm_bitreversal2.s and I have made sure that file is in the source file.

I have added .h files which are in STM32Cube_FW_F0_V1.11.0\Drivers\CMSIS\DSP\Include and the source files which are in STM32Cube_FW_F0_V1.11.0\Drivers\CMSIS\DSP\Source to my project .

Any suggestions or help would be very appreciated.

Best regards.

Which seems a duplicate of you qestion here: https://community.st.com/s/question/0D53W0000055YqzSAE/cmsis-fft-problem-in-stm32cubeide

As said, check the arm_bitreversal2.s source file.

Not doing much in assembly, but GCC, Keil and IAR assembly syntax is not fully compatible.

CubeIDE is supposedly GCC.
