Getting started with Eclipse IDEs and Arm MDK for the Arm CMSIS-DSP library

Overview

This document describes the steps required to integrate the Arm CMSIS-DSP library with C code generated from the ASN Filter Designer’s CMSIS-DSP C code generator into an Eclipse-based IDE STM32CUBE-IDE and Arm MDK (μVision IDE).

The steps mentioned in this document are common for other Eclipse-based IDEs, and therefore portable. As an example, we will generate a project in the STM32CUBE-IDE and for the STM32F446RE microcontroller based on a Cortex-M4.

Steps for including the Arm CMSIS-DSP library in Eclipse-based IDE project

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

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

you should see the following file structure in the repository.

Clone the CMSIS git repository in a separate folder using the command git clone https://github.com/ARM-software/CMSIS.git Structure: CMSIS, Device, ARM.CMSIS.pdsc, Readme.md

2. Create a folder in your project and name it DSP. We have to copy all the CMSIS dependences in this folder.

3. Open the CMSIS repository navigate to CMSIS\Lib\GCC path and copy the libarm_cortexM4lf_math.a file (Cortex-M4) and paste it in the DSP\Lib folder in your project. For Cortex-M7 based microcontroller projects, copy libarm_cortexM7l_math.a, for Cortex-M3 libarm_cortexM3l_math.a, and finally for Cortex-M0 libarm_cortexM0l_math.a

4. Navigate to the CMSIS folder in your repository, copy the Include folder and paste it into the DSP folder in your project.

Navigate to the CMSIS folder paste it into the DSP folder

5. Now to add CMSIS header files to the project: go to project properties and navigate to Paths and Symbols under the option C/C++ General.

6. Click on the Add option and type DSP/Include in the popup and then click OK.

DSP Include

7. Click on the Library Paths tab and then click on the Add button. Type DSP/Lib in the popup and click on the OK button.

8. Click on the Libraries tab and then click on the Add button. Type arm_cortexM4lf_math in the popup and click on the OK button.

Remove the lib prefix and .a extension from the library file name to get specific text to be added to the microcontroller platform.

9. Click on the Symbols tab and then click on the Add button. Type ARM_MATH_CM4 (if using a Cortex-M4) in the popup and click on the OK button.

Please refer to the table below for symbol definition for other cores.

ARM_MATH_CM0 Cortex-M0 core. ARM_MATH_CM4 Cortex-M4 core.
ARM_MATH_CM0PLUS Cortex-M0+ core. ARM_MATH_CM7 Cortex-M7 core.
ARM_MATH_CM3 Cortex-M3 core.
ARM_MATH_ARMV8MBL ARMv8M Baseline target (Cortex-M23 core).
ARM_MATH_ARMV8MML ARMv8M Mainline target (Cortex-M33 core).

10. Now click apply and close button, now copy the code you have generated using the ASN Filter Designer to main.c and build the project.

Steps for including the Arm CMSIS-DSP library to Arm’s μVision IDE

1. Open your μvision project.

2. Navigate to the Manage Run-Time Environment option.

3. As shown below, you should see a popup, click on CORE and DSP checkboxes under CMSIS and then press the OK button.

The IDE will then automatically add the necessary files to your project.
