DSP library with STM32F7

[MMett]

Where can I find the DSP library for the STMF7 processors? In the CMSIS DSP Software Library documentation I read that I can use the arm_cortexM7lfsp_math.lib (Little endian and Single Precision Floating Point Unit on Cortex-M7). On the website of ST (https://www.st.com/en/embedded-software/stm32-standard-peripheral-libraries.html?querycriteria=productId=LN1939) it only goes up to F4.

Should be all the pieces you need under the HAL code trees, within the Driver CMSIS DSP branches.​

If I get the package: STM32F4xx_DSP_StdPeriph_Lib_V1.8.0

I only see M4 libraries in the folder: en.stm32f4_dsp_stdperiph_lib/STM32F4xx_DSP_StdPeriph_Lib_V1.8.0/Libraries/CMSIS/Lib/ARM .

I did not find any STM32F7xx_DSP_StdPeriph_Lib.

There isn't an SPL. There is now the HAL, unpack the CubeF7 archive, and build the DSP libraries. ​

Ok, I found them, thank you!

Hello,

I would like to suggest you to have a look at AN4841 (Digital Signal Processing with STM32, software expansion for STM32Cube).

You have the application note document besides to the firmware package with DSP examples for STM32F4 and STM32F7, based on STM32Cube firmware.

hi all, 

i completed the setup and configured some DSP instructions and executed them on the STM32F7 nucleo board using AN4841 document, i see that during the debug operation power LED on the board is going Dim(dull) instead of being RED.

Is this a common scenario whenever we run DSP instructions(like fft, fir etc..) or is there any other issue.??

Kindly can anyone confirm me this and help me to overcome if there is an issue.

Thanks in advance.
