Now the OpenSTM32 system workbench is downloaded into the Software and Toolchain folder (Figure 1).

Browse to the System Workbench for STM32 installer to download and install System Workbench. If you experience issues during installation, see the FAQs on the System Workbench website. Build and run the FreeRTOS demo project.

Figure 1. STM32 installer downloaded into Software and Toolchain folder.

Now let’s install that software.

Steps:

1. Click on the STM32 installer shown in Figure 1.

2. Now it is trying to install (Figure 2). In Figure 3, you can see that it is throwing some errors. But it is trying to execute that exe. Please be patient.

FreeRTOS example for STM32. Follow this FreeRTOS tutorial on the STM32 microcontroller to see how it is easy to scale your project and still have full control of operations. First of all, we need to build a template that includes all necessary FreeRTOS source files. We need to import the FreeRTOS folder to our project tree. Stm32 cubeMx FreeRTOSPosted by dtvonly on May 28, 2018Hi. I am using the stm32VLdiscovery board. I followed the example on Youtube to blink and LED on the board through PC8 or PC9 using FreeRTOS. All configurations were done in stm32 cubeMX. I did not add any additional task but used the default startup task.

4. Accept the terms of the license agreement and click next (Figure 5).

5. Then it will ask you to select the installation path (Figure 6), the place where exactly you want to store these installation files. You have to select your drive here. By default, it will consider a C drive. If you don’t have enough memory in your C drive, then you can change it. Now let’s change the drive to D drive, as shown in Figure 7. Then click next. It will create the folder AC6SystemWorkbench.

Figure 6. Choosing the installation path.

6. It will install the STM32 system workbench, a driver for in-circuit debugger and programmer, i.e., ST-Link version 2 and driver for that, and the ST-Link server. All three packs marked in Figure 8 are going to be installed. Now let’s click next.

Figure 8. Selecting the packs to install.

7. After that, you will get a setup shortcuts window (Figure 9). Just click on next.

8. After that, you will see another popup window showing the installation settings. The popup shown in Figure 10 contains information about the installation path and chosen installation packs. Let’s click next.

Figure 10. Information of installation settings.

9. Now the software is being installed (Figure 11). MAC and Ubuntu guys, for you also, this window will pop up when you run your binaries, and then you have to install this software.

10. You should see the system workbench folder in D drive now. Observe Figure 12. System workbench folder has been created, and all the files are being copied into that folder (Figure 13). Let’s wait until it finishes the installation.

12. The installation is complete (Figure 15) and now let’s click next.

13. After clicking next, it will ask your permission to install the device driver (Figure 16). Let’s click next here.

Figure 16. Granting permission to install the device driver.

14. Now the ST-Link drivers are successfully installed on your computer (Figure 17). Now let’s click finish. After that, you will get a processing window (Figure 18), click next.

Steps to launch the application:

1. The application is installed under the Ac6 folder.

2. You can see the installed application under the Ac6 folder, as shown in Figure 21. Just double-click over that to launch the open STM32 system workbench. This is one method.

Figure 21. Launching the application installed under the Ac6 folder.

3. Otherwise, if you are on Windows, you can go to all files, find the system workbench (Figure 22), and then launch it.

As the system is based on FreeRTPS it does not have any runtime dependencies. To compile and run the system on a microcontroller (MCU), you need a cross-compiler. Now, compiling and programing through the linux terminal is only supported with STM32 MCUs, once the we only have linker files for it. If you are using a especific IDE, you can use the system just importing the source and headers files.

Compiling and programing for STM32 on Linux

To use FreeRTPS+FreeRTOS with STM32 you will need the ARM Cortex-M port of gcc (arm-none-eabi) and OpenOCD. Next we show the installation of necessary tools, this tutorial used Ubuntu 16.04. First, install the tools required to get and compile the system.

Now, we going to install the pre-built compiler toolchain for ARM Cortex-M. On Ubuntu, we can do this through an Ubuntu Personal Package Archive (PPA) maintained by “GCC ARM Embedded Maintainers” team:

Now we need to build OpenOCD from source, this way we have the recent files of the STM32 family. The following lines put the source in ~/openocd and install it into /usr/local:

Stm32 Freertos Uart

Finally, we need to get and compile the files of the system from Github. The following lines will make a copy of the latest files in ~/FreeRTPS-FreeRTOS folder and will compile the system.

Now you can use the 4 demos included in the FreeRTPS-FreeRTOS. On next lines we present the description and how to program the STM32 Discovery with each demo example.

App listener This example implements a single String subscriber. To program it on the STM32, plug the board to the computer through a USB cable and put the following line on terminal.

App talker This example implements a single String publisher. To program it on the STM32, plug the board to the computer through a USB cable and put the following line on terminal.

App pid This example implements a 32 bit unsigned int publisher, a 32 bit unsigned int subscriber and a PID closed loop control. To program it on the STM32, plug the board to the computer through a USB cable and put the following line on terminal.

App pubpidsetpoint This example implements a 32 bit unsigned int publisher. It can be used with PID example, on a separate board, to test the PID closed loop. To program it on the STM32, plug the board to the computer through a USB ca
