User interface

This chapter provides a detailed description of the user interface.

Start Development wizard

Upon starting MCUXpresso Config Tools, you are automatically welcomed by a startup wizard. With this wizard, you can create a configuration or open an existing one.

Note: To skip the wizard on subsequent startups, select the Always open last configuration checkbox below the Open an existing configuration option. You can also perform the same action by selecting the Automatically open previously used configuration checkbox in Preferences.

Start development wizard

Note: The content of this wizard is similar to the wizard that you open by selecting File > New in the Menu bar.

Creating, saving, and opening a configuration

In this context, configuration stands for common tools settings stored in an MEX (Microcontrollers Export Configuration)file. This file contains the settings of all available tools and can be used in both web and desktop versions.

The folder with the saved MEX file must contain exactly one project file to be able to parse the toolchain project. The file type depends on the toolchain of the project and can be one of the following:

Table Supported toolchain project files

Supported toolchain project files

Toolchain	Project file
IAR Embedded Workbench	EWP
Keil MDK uVision	UVPROJX
ARM GCC	CMakeLists.txt
CodeWarrior with SDK	.cproject
Open-CMSIS csolution	*.cbuild-gen-idx.yml
SDK West	project_info.json

Creating a new configuration

You can create a configuration from the Start development wizard or by selecting File > New from the Menu bar.

If you start creating your development for any NXP board or kit, we recommended you start with an MCUXpresso SDK example to create a configuration for a board or a kit. Such a configuration contains board-specific settings. If you select a processor, the configuration will be empty.

After the new configuration is created, you can continue by importing an existing configuration from an MEX file. It is useful if you already have a configuration available or if you want to reuse a previous configuration. To import an existing configuration from an MEX file, select File > Import… > Import configuration (*.mex) from the Menu bar.

Cloning an SDK example

You can create a configuration by cloning an SDK example project for IAR Embedded Workbench, Keil μVision, CodeWarrior Development Studio, and/or GCC ARM Embedded (command line). The resulting project contains all source files and libraries to build the project and can be easily customized, shared, or put under a control version system.

Note: The creation (cloning) of the projects based on the SDK examples will no longer be supported in the future releases of the MCUXpresso Config Tools. Instead, use use the MCUXpresso SDK CMake, Kconfig-based build. For detailed documentation, see the SDK Build And Configuration System documentation.

SDK example cloning is supported for MCUXpresso SDK 2.2 and higher.

Note: To be able to clone an SDK example or create a “hello_world” project, you must first download an SDK package. For more information about SDK packages offered by NXP Semiconductors, refer to the MCUXpresso Software Development Kit.

Note: If the server is unavailable, and device data is not cached, creating the project fails.

Cloning SDK

To clone an SDK example, do the following:

1. In the Start development wizard, select Create a new configuration based on an SDK example or a “hello world” project. Alternatively, in the Menu bar, select File > New.

2. Click Next.

3. Specify the path to your locally saved SDK package.

4. Choose the toolchain that you want to create the project for.

5. Choose the SDK example that you want to clone.

6. Specify a base project directory to save your project to.

7. Specify the project name.

8. Click Finish.

You can also create a basic, minimally customized “hello_world” project without having to select an SDK example from the package. To create a “hello_world” project, do the following:

1. In the Start development wizard, select Create a new configuration based on an SDK example or a “hello world” project. Alternatively, in the Menu bar, select File > New.

2. Click Next.

3. Specify the path to your locally saved SDK package.

4. Choose the toolchain that you want to create the project for.

5. Select Create “hello_world”.

6. Specify a base project directory to save your project to.

7. Specify the project name.

8. Click Finish.

The Config Tools Overview window shows the details of the configuration and supported tools. Now, select a tool by clicking its icon.

Creating a new toolchain configuration

You can create a configuration for an existing toolchain project. Once done, configuration files associated with the project are updated directly.

MCUXpresso Config Tools currently supports the following toolchains:

• IAR Embedded Workbench

• Keil MDK uVision

• Arm GCC

• CodeWarrior with SDK

• SDK West

Note: For proper functionality of Config Tools, it is required that the toolchain project originates from the SDK package or has been created using the cloning feature of Config Tools.

To create a configuration based on an existing IDE/Toolchain project, do the following:

1. In the Start development wizard, select the Create a new configuration based on an existing IDE/Toolchain project. Alternatively, in the Menu bar, select File > New.

2. Click Browse.

3. Select the project file and confirm by clicking OK.

4. Click Finish.

Creating a new configuration for SDK West

You can create a configuration, for new format of SDK project (https://mcuxpresso.nxp.com/mcuxsdk) that uses the West tool.

If you are also using Visual Studio Code, you can open Config Tools from there via the context menu for the project. This also opens or creates a new configuration if it does not exist. Otherwise, it is possible to handle it manually using the following steps:

1. Before using config tools, run the west command to get the project information for Config tools from the SDK project files, for example:

   west cfg_project_info -b lpcxpresso55s69 ...mcuxsdk/examples/demo_apps/hello_world/ -Dcore_id=cm33_core0
   

   This results in the creation of the project information json file that is searched by the config tools when the configuration is created. The parameters of the command should match the build parameters that will be used for the project.

2. In the Start development wizard, select Create a new configuration based on the existing IDE/Toolchain project, and select the created “cfg_tools” subfolder as a project folder (for example: …mcuxsdk/examples/demo_apps/hello_world/cfg_tools/).

Creating a new configuration for Zephyr RTOS

You can create a configuration, that generates .dtsi file with pin control that is possible to include in the board device tree. There will be offered only processors/boards

After the configuration, move the generated file to the proper location in your Zephyr board, application folder, or repository. Consult Zephyr RTOS documentation for the appropriate placement and usage of the Pin Control file.

In the context of Zephyr RTOS, only the Pins tool is supported allowing pin routing and configuration.

You can create a configuration that generates a .dtsi file with pin control that can be included in the board device tree. Only processors and boards compatible with the Zephyr (https://www.nxp.com/zephyr) will be offered as the SDK version.

1. In the Start development wizard, select Create a new standalone configuration for Zephyr RTOS. Alternatively, in the Menu bar, select File > New.

2. Click Next.

3. Select the processor, board, or kit from the list. Note: When working offline, only locally stored options will be available. For further details, refer to the Working Offline section.

4. Name your configuration. Optionally, select the processor package, core, and SDK version.

5. Click Finish.

Using the generated files

There are some additional manual steps needed to integrate the generated files:

1. After the configuration, write the files to disk using the Update Code command or via the Export command.

2. Move the generated device tree (.dtsi) file to the proper location in your Zephyr board, application folder, or repository. If you have a custom hardware, it is a common practice to create a custom board in the Zephyr RTOS rather than modifying standard board files that are shared by many projects. Consult Zephyr RTOS documentation for details on how to work with pin control and the steps for creation of the custom board. Note: : Alternatively you can leverage content of the .dtsi file for creation of the device tree overlay file for your application.

3. In case features not supported by Zephyr RTOS are used, the Pins tools provides pin_mux.c/h files. It is necessary to add pins.c/h to your cmake file so they are part of the build and call the generated functions in your code.

Limitations

The pin configuration and routing cannot be restored from the generated .dtsi file because there is no import functionality for this format. Keep the original .mex file for further regeneration of the file(s).

Creating a new standalone configuration

You can create a configuration that is not part of any toolchain project.

You can later include this configuration in a project by saving the configuration (MEX) file in the toolchain project folder.

Creating a new configuration

To create a standalone configuration, do the following:

1. In the Start development wizard select Create a new standalone configuration for processor, board, or kit. Alternatively, in the Menu bar, select File > New.

2. Click Next.

3. Select the processor, board, or kit from the list. Note: If you are working offline, you will only see locally saved options. For more information, see the Working offline section.

4. Name your configuration. Optionally, you can select processor package, core, and SDK version.

5. Click Finish.

Saving a configuration

To save your configuration for future use, select File > Save from the Menu bar.

To save a back-up of your configuration, do the following:

1. In the Menu bar, select File > Save Copy As.

2. In the dialog, specify the name and destination of the configuration.

3. Click Save.

Opening an existing configuration

To open an existing configuration, do the following:

1. In the Start development wizard, select Open an existing configuration. Alternatively, in the Menu bar, select File > Open.

2. Click Browse to navigate to your configuration file.

3. Select the configuration file and click Open.

4. Optionally, select Always open last configuration to skip the Start development wizard and load the last-saved configuration by default.

User templates

You can export and store the current configuration as a user template for later use as a reference configuration file.

Export template

The exported template is available in the New Configuration wizard and can be used to create a configuration. You can also define custom labels for pins or identifiers prefixes for #define in the generated code. You can export the configuration by selecting, in the Menu bar, File > Export > Tools Configuration > Export Configuration as Template.

Create a new configuration from the template

Note: The templates are stored in at the following location on your local hard disk: {$user}/.nxp/{tools_folder}/{version}/templates.

Importing sources

You can import source code files to use as a basis for further configuration.

Note: You can import only C or DTSI files containing valid YAML configuration blocks generated by the Config Tools. The configuration is reconstructed from the YAML block and the rest of the imported file is ignored.

To import source code files, do the following:

1. In the Menu bar, select File > Import….

2. From the list, select MCUXpresso Config Tools > Import Source.

!(/_images/n_toolbar_properties_button.png)	Opens the Functional group properties window

Note: Red/orange background indicates errors/warnings in the configuration.

Functional group properties

In the Functional Group Properties window, you can configure several options for functions and code generation. Each setting is applicable for the selected function. You can specify the generated function name, select the core (for multicore processors only) that is affecting the generated source code, or write a function description (this description is generated in the C file). You can also add, copy, and remove functional groups as needed.

Aside from name and description, you can choose to set parameters for selected functional groups.

Functional group properties are specific for individual Config Tools:

Pins tool:

• Set custom #define prefix- If this property is set, the specific custom prefix is used for macros generated into the pin_mux.h. Otherwise the name of the functional group is used as the prefix.

• Prefix - The custom prefix string. If it is empty, no prefix is used.

• Clocks gate enable - If this property is enabled, the clock gate is enabled in the generated code. The clock gate is needed for access to the peripherals, so have it enabled elsewhere.

• Core (for multicore processors only) - Selects the core that is used for executing this function.

• Full pins initialization - If this property is set, all features of the pins are fully initialized in the generated function even if matches the after-reset state of the processor. If it is not set, values “Not specified” or “No init” can be selected.

• De-initialization function - If this feature is set, an additional function that sets all pins and peripheral signals in this functional group to their after-reset state is generated. The new function has a suffix _deinit by default.

• Set custom de-initialization function name- Allows specifying a user-defined name of the de-initialization function.

Clocks tool:

• Set custom #define prefix - If this property is set, the custom prefix is used for macros define in clock_config.h. Otherwise the name of the functional group is used as the prefix.

• Prefix - The custom prefix string. If it is empty, no prefix is used.

• Other settings - The processor-specific settings are specific for each processor. See the tooltips for details.

Peripherals tool:

• Prefix - It is used for identifiers, constants, and functions related to the functional group that is used in generated code. If it is not specified, no prefix is used.

TEE tool:

• Set custom #define prefix - If this property is checked, the custom prefix is used for macros define in the generated code. Otherwise, the name of the functional group is used as the prefix.

Registers view

The Registers view lists the registers handled by the tool models. You can see the state of the processor registers that correspond to the current configuration settings and also the state that is in the registers by default after the reset. The values of the registers are displayed in the hexadecimal and binary form. If the value of the register (or bit) is not defined, an interrogation mark “?” is displayed instead of the value.

Registers view

The Registers view contains several items.

Table Registers

Table Color codes

Color codes

Color	Description
Yellow background	Indicates that the bitfield has been affected by the last change made in the tool.
Gray text color	Indicates that the bitfield is not edited and the value is the after-reset value.
Black text	Indicates the bit-fields that the tool modifies.

Note: When the Peripherals tool is active and register initialization components are used, the user can perform manual changes to some of the displayed values.

Note: This view contains registers for the selected tool. The view uses registers as internal parameters but it might not handle all the register writes needed in the code. The register writes are done inside the SDK functions that are called by the generated code. There might be additional registers accessed in the SDK code during the setup process, and such register writes are not known to the tool and are not displayed in the registers view.

Log view

The Log view shows user-specific information about MCUXpresso Config Tools operations. The Log view can show up to 100 records across all tools in chronological order.

Each log entry consists of a timestamp, the name of the tool responsible for the entry, severity level, and the actual message. If no tool name is specified, the entry was triggered by shared functionality.

You can filter the content of the Log view using the combo boxes to display only specific tool and/or severity level information. Filters in different tools can be set independently.

Buffered log records are cleared using the clear button. It affects Log views across all tools.
