STM32CubeIDE

The provided example projects can be run on the STM32 targets (STM32F401RE) using the STM32Cube IDE.

Note

This guide shows how to use the example projects but the same steps can be executed to run the other STM32Cube IDE projects. See Demo Applications for an overview.

Execute the following steps to get the example projects up and running. Please also refer to the STM32CubeIDE documentation by STM in case of any trouble.

Note

Depending on where you obtain the code, i.e. from the SDK installer or the GitHub repository, certain steps may differ. The projects that come with the SDK installer (found at [INSTALL_DIR]\Device\Projects\) are provided as zip-file and will be copied into the STM32CubeIDE workspace. The projects downloaded or cloned from the AFBR-S50 GitHub repository are already unpacked an must be imported but not copied into the STM32CubeIDE workspace (otherwise the project references may become invalid).

In order to run provided project, execute the following steps:

Install STM32CubeIDE

Download and install the STM32CubeIDE:

1. Go to https://www.st.com/en/development-tools/stm32cubeide.html
2. Click on Get Software and select and download the correct installer.
3. Install the IDE.
4. Go to https://www.st.com/en/development-tools/stm32cubeide.html for more information.

Import a Project

Import the project archive files:

1. Go to STM32CubeIDE and close the Welcome Page
2. Click on Menu > File > Import...
3. Select General > Existing Projects into Workspace and click Next
4. Select your project for import:
   • If importing a project as zip file as provided by the SDK installer:
     1. Click on Browse... in the Select archive file section
     2. Browse to [INSTALL_DIR]\Device\Projects\ (default is C:\Program Files (x86)\Broadcom\AFBR-S50 SDK\Device\Projects\
     3. Select the required project archive (e.g. AFBR_S50_Example_STM32F04RE.zip) and click Open
   • If importing a project from the local directory as provided by cloning/downloading the GitHub repository:
     1. Click on Browse... in the Select root directory section
     2. Browse to [REPOSITORY_ROOT]\Projects\STM32CubeIDE\
     3. Select the required project root folder (e.g. AFBR_S50_Example_F401RE) and click Select Folder
     4. IMPORTANT: Click Nextand disable the check at Copy projects into Workspace. (Otherwise, the references to the source files will be messed up!)

5. Click Finish

Build the Project

1. Go to STM32CubeIDE -> Project Explorer and select the project to build.
2. Go to Menu -> Project -> Build Project to build the project.

Debug the Project with the STLink debugger

1. Connect the STM32F401RE Nucleo Board via USB cable.
2. Select the project to debug in the Project Explorer of the STM32CubeIDE.
3. Select Run > Debug As > STM32 C/C++ Application.
4. Click on OK (Everything should be setup correctly by default).

5. If the program breaks at the main() function, hit the Resume button.

Connect the UART interface to PC

Follow the steps in the Serial (UART) Connector section to connect to the board via UART.

Display the Measurement Values

Note

This applies only for the Example Apps. In case of the Explorer App, use the AFBR-S50 Explorer GUI instead.

Display the measurement values on a PC via an UART terminal:

1. Open a terminal (e.g. Termite) and open a UART connection using 115200 bps, 8N1, no handshake connection.

   Baud rate	Data Bits	Stop Bits	Parity	Flow Control
   115200 bps	8	1	none	none

2. Range values will start to occur on the terminal as soon as the program starts its execution.
