How to use ARM CMSIS DSP lib in ModusToolbox2.4

[Ray_Liang]

Hi all,

I am looking for a guide line about how to enable the DSP lib to use the dsp API in PSoC6 CM4 project.

Is there a document here？ Or can someone help to provide setup steps?

Regards,

Ray

The following linker is talking about the DSP lib,  you can refer to it:

Lingling,

Thanks! Because the link you sharing was an old topic in 2020, which is using MTB2.1, I am looking somethings newer.

And there is also somethings changed on https://github.com/ARM-software/CMSIS_5/ 

Actually, I find a way to use DSP lib now. Here is the step I try:

Step 1 (For the user does not install MDK IDE, if user already install MDK IDE, skip this step )

Clone the CMSIS git repository in a separate folder using the command

git clone https://github.com/ARM-software/CMSIS.git

I run it in the MTB2.4 terminal , and git clone to workspace folder, as below:

Step2  Modify makefile to add the path of DSP library, just like the post you sharing.

• DSP_DIR=../CMSIS/CMSIS/
• INCLUDES=$(DSP_DIR)/Include
• VFP_SELECT=hardfp
• LDLIBS=$(DSP_DIR)/Lib/GCC/libarm_cortexM4lf_math.a

(For the user installed MDK IDE, should use the path of MDK DSP lib)

Then, it should be OK to call the math function.
