BLDC Scalar Sensorless XMC™1300

Disclaimer: This is a community code example (CCE) released for the benefit of the community users. These projects have only been tested for the listed BSPs, tools versions, and toolchains documented in this readme. They are intended to demonstrate how a solution / concept / use-case can be achieved on a particular device. For official code examples, please click here.

This community code example (CCE) demonstrates sensorless three-phase BLDC motor control application using XMC1300 Boot Kit. In order to test this software, XMC1000 Motor Control Application Kit is needed.

Requirements

ModusToolbox™ software v3.1 or later (tested with v3.1)
SEGGER J-Link software v7.90a
Programming language: C
Associated parts: XMC1300 MCU

Supported toolchains (make variable 'TOOLCHAIN')

GNU Arm® embedded compiler v11.3 (GCC_ARM) - Default value of TOOLCHAIN

Supported Kits

XMC1300 Boot Kit (KIT_XMC13_BOOT_001)

Hardware setup

Before using this code example, make sure that the XMC1300 board is correctly connected to the PMSM Low Voltage 15W Motor Card which also needs to be supplied by an external DC power supply (12V to 24V) from its power jack. Please see this User Manual for more details. A complete hardware setup example can be seen in Figure 1 below.

Note: Make sure that the SWCLK is on before using the debugger as shown in Figure 2.

Software setup

This code example uses Micro Inspector Pro application by default to run and control the motor from a GUI. Click here to download the application.

Please follow the steps below to control the motor from the Micro Inspector Pro application.

Using the code example

Create the project and open it using one of the following:

In Eclipse IDE for ModusToolbox™ software (recommended)

Click the New Application link in the Quick Panel (or, use File > New > ModusToolbox™ Application). This launches the Project Creator tool.
Select the kit KIT_XMC13_BOOT_001 from the XMC™ BSPs list shown in the Project Creator - Choose Board Support Package (BSP) dialog.
In the Project Creator - Select Application dialog, choose the example from the list Community Code Examples by enabling the checkbox.
(Optional) Change the suggested New Application Name.
The Application(s) Root Path defaults to the Eclipse workspace which is usually the desired location for the application. If you want to store the application in a different location, you can change the Application(s) Root Path value. Applications that share libraries should be in the same root path.
Click Create to complete the application creation process.
To build the project, click Build Application from the Quick Panel.
To start the debugging session to run the motor, click Generate Launches for "YourApplicationName" in Quick Panel. Then click to YourApplicationName Debug (Jlink). A debugging window will appear and the session will automatically pause in a breakpoint. Click Resume button from the above toolbar to continue the session.
While the debugging session is running, open the Micro Inspector Pro application. Click Open Workspace button from the upper left corner.

Figure 3. Opening the workspace folder in Micro Inspector Pro

Find the "BLDC_SCALAR_SL_XMC13_uCProbe.wspx" file from your ModusToolbox workspace folder and select Open. A pop-up window will appear to show the existing elf file. Select the one shown and click Open.

Figure 4. Selecting the elf file

To run and control the motor speed from the GUI, switch to BLDC: Speed Control mode and click Run button.

Note: If you face any issues or errors with Micro Inspector GUI while the kit is in debug mode, please reset the GUI while the debug session is on and restart from step 9.

Figure 5. Switching to running mode

Press Motor Start to run the motor. You can also adjust the motor speed by changing the value under Setting Target Speed.

Figure 6. Motor control part of the running mode

Right click the Oscilloscope tab and select New Vertical Tab Group in order to observe your parameters from the oscilloscope on the right side while observing the motor control parameters on the left side simultaneously.

Note: This code does not use the Device Configurator in ModusToolbox. All peripheral definitions and initializations are directly integrated within the software using low level drivers by calling the necessary libraries. When the user wants to change a configuration variable or parameter, it should be done within the code in the user config header files rather than in the Device Configurator.

For more details, see the Eclipse IDE for ModusToolbox™ software user guide (locally available at {ModusToolbox™ software install directory}/ide_{version}/docs/mtb_ide_user_guide.pdf).

In command-line interface (CLI)

ModusToolbox™ software provides the Project Creator as both a GUI tool and the command line tool, "project-creator-cli". The CLI tool can be used to create applications from a CLI terminal or from within batch files or shell scripts. This tool is available in the {ModusToolbox™ software install directory}/tools_{version}/project-creator/ directory.

Alternatively, you can manually create the application using the following steps:

Download and unzip this repository onto your local machine, or clone the repository.
Use a CLI terminal to invoke the "project-creator-cli" tool. On Windows, use the command line "modus-shell" program provided in the ModusToolbox™ software installation instead of a standard Windows command-line application. This shell provides access to all ModusToolbox™ software tools. You can access it by typing modus-shell in the search box in the Windows menu. In Linux and macOS, you can use any terminal application.

The "project-creator-cli" tool has the following arguments:

Argument	Description	Required/optional
`--board-id`	Defined in the `<id>` field of the BSP manifest	Required
`--app-id`	Defined in the `<id>` field of the CE manifest	Required
`--target-dir`	Specify the directory in which the application is to be created if you prefer not to use the default current working directory	Optional
`--user-app-name`	Specify the name of the application if you prefer to have a name other than the example's default name	Optional

The following example clones the "BLDC Scalar SL XMC13" application with the desired name "cce-mtb-xmc-bldc-scalar-sl" configured for the KIT_XMC13_BOOT_001 BSP into the specified working directory, C:/mtb_projects:

project-creator-cli --board-id KIT_XMC13_BOOT_001 --app-id cce-mtb-xmc-bldc-scalar-sl --user-app-name cce-mtb-xmc-bldc-scalar-sl --target-dir "C:/mtb_projects"

Note: The cloned application contains a default BSP file (TARGET_xxx.mtb) in the bsps folder. Use the Library Manager (make modlibs command) to select or add a different BSP file, if required. If the selected kit does not have the required resources or is not supported, the application may not work.

Import the required libraries by executing the make getlibs command.

Various CLI tools include a -h option that prints help information to the terminal screen about that tool. For more details, see the ModusToolbox™ software user guide (locally available at {ModusToolbox™ software install directory}/docs_{version}/mtb_user_guide.pdf).

In third-party IDEs

Note: Only VS Code is supported.

Follow the instructions from the In command-line interface (CLI) section to create the application, and import the libraries using the make getlibs command.
Export the application to a supported IDE using the make <ide> command.

For a list of supported IDEs and more details, see the "Exporting to IDEs" section of the ModusToolbox™ software user guide (locally available at {ModusToolbox™ software install directory}/docs_{version}/mtb_user_guide.pdf).
Follow the instructions displayed in the terminal to create or import the application as an IDE project.
