Hello there,

I was wondering either there is a DSP library for stm32f4 with HAL framework?

No. There is no hardware to be abstracted from...

However, the ARM

CMSIS DSP Library

comes bundled with the CubeF4 library, since v1.4.0, in  STM32Cube_FW_F4_V1.4.0\Drivers\CMSIS\DSP_Lib\ , including examples. JW

It also didnt make to much sense to me but since i have seen a package called ''...DSP_STDPeriph...'' it made me think that it is important.

I have found the examples, thank you.I run through some of the functions from there and I am a bit confised- Apart from some more complex functions there seem to be functions for multiplying 2 float values. Does this mean that when I want to do float * float I need to use the DSP library for that for speed optimalisation?

Well one would hope your compiler/tool-chain is smart enough to use the FPU instructions, and math libraries when you check the ''Use the FPU'' box.

I am using OpenSTM32 framework and I do have hardfloat selected. Then I hope it works :P. Thank you for the explanation.
