3 SDK - Download and Installation

3.1 Using the SDK Online

A quick and easy way to start working with the SDK is to use TI Resource Explorer on dev.ti.com. This online tool lets you explore the contents of the SimpleLink MSP432E4 SDK. You can build the examples directly using the cloud version of Code Composer Studio. If you choose to use the SDK online, there is no need to download anything to your local computer or install any tools.

3.2 Installing the SDK

You can also download the SimpleLink MSP432E4 SDK from TI Resource Explorer or the software product page on TI’s website.

4. Quick Start for CCS IDE (CCS or GCC Projects)

This section is going to cover the required settings for a CCS installation and how to build and load examples

4.1 Download and Installation

Download CCS

During the installation, the following options are recommended:

• We recommend that you use the default installation folder

• Make sure that SimpleLink MSP432 low power + performance MCUs is selected. You can select additional processor support options as needed.

• To use a debug probe, select TI XDS Debug Probe Support and any other options you would like.The MSP-EXP432E401Y Launchpad uses TI XDS Debug Probe by default.

• Make sure that MSP432 Tool Chain is installed by checking for updates under Help → Check for Updates

4.1.1 Discovering the SDK in CCS

Install the SDK in the default location pointed to by the installer - C:\ti and Re-start CCS. CCS will automatically detect the latest install.

4.2 Running Your First Example

This section will show how to import, build and load an example

4.2.1 TI Resource Explorer

A quick and easy way to start working with the SDK is to use the TI Resource Explorer on dev.ti.com/tirex. Step by step instructions are available here.

4.2.2 Import via CCS IDE

• Open CCS
• Choose Project → Import CCS Projects from the menu.
• Select the Browse button in the Import CCS Projects dialog and select the the directory <SDK_INSTALL_DIR>/examples

• The SDK provides no RTOS, TI-RTOS and FreeRTOS based examples. TI-RTOS and FreeRTOS examples have the word “tirtos” or “freertos” in the project name

• CCS discovers both CCS and GCC based examples.

• Importing TI-RTOS and FreeRTOS examples will bring import kernel projects in the same workspace. The kernel project is a dependent project and will be automatically built when the example is built. For more details and how change configurations look at the SimpleLink MSP432E4 SDK User’s Guide.

• Select any Code Example you would like to use. In this example gpiointerrupt_MSP_EXP432E401Y_tirtos_ccs is chosen

• Choose target configuration

You may have to expand the project in the Project Explorer window to view the target configuration. If you are using the Launchpad, double click on MSP432E401Y.ccxml

• In order to use FreeRTOS within CCS, you must specify the location of the FreeRTOS installation

• Build and Download

Plug in your launchpad, Click the build and download icon in CCS. The RTOS build for the first time takes a couple of minutes.

• The XDS110 may require a firmware update. If a firmware update is requested click ok.

www.ti.com/lit/pdf/slau575 has more details about MSP432E4 device

• Every RTOS example has a README.html that details the Example Application Design Details and how each example works. This feature will soon be added to the No RTOS based examples

4.3 Create a new SDK based User Application

Do not use the New Project Creation Wizard

• Start with one of the example projects or empty project template shipped inside the SDK. Each software component in the SDK comes with its own set of examples. If your project depends on multiple TI provided software libraries, start from the empty template then add the necessary components into your projects.

• Import one of the empty project template shown below to your IDE and start your application from there. All the necessary include paths and SDK specific defines if any are already part of the Empty Project Template

4.3.1 Non-RTOS Based Empty Project Template

4.3.2 TIRTOS Based Empty Project Template

4.3.3 FreeRTOS Based Empty Project Template

5. Quick Start for IAR IDE

This section is going to cover the required settings for a IAR installation and how to build and load examples.

5.1 Download and Installation

Download and install IAR Embedded Workbench for ARM. You can get IAR for ARM here.

• Make sure to select TI XDS as one of the debug probe drivers. You may also select other drivers. The driver will be installed towards the end of the installation of IAR.

IAR 8.11.3 requires a patch for proper debug support with the MSP-EXP432E401Y LaunchPad. The patch is provided in the SDK in the C:\ti\simplelink_msp432e4_sdk_1_55_00_21\tools\iar directory or at www.iar.com/mypages. This patch only works with IAR 8.11.3 and should not be used with any other IAR versions.

To install the patch, simple extract the zip where you have IAR Embedded Workbench installed within the \Embedded Workbench 8.0 directory.

For more information refer to the PatchReadme-8.11.3.14204.html file contained within the patch.

5.1.1 Configuring Custom Argument Variables

Before starting to work with any of the projects in the SDK, you need to load a set of variables that will be set for your current workspace:

• Choose Tools -> Configure Custom Argument Variables

• Click Global -> Import

• Import the custom argvars from the SDK. The argvars are stored in a SIMPLELINK_MSP432E4_SDK.custom_argvars file, which is located in the tools directory of the SDK (<SDK_INSTALL_PATH>/tools/iar/SIMPLELINK_MSP432E4_SDK.custom_argvars)

• You can open (<SDK_INSTALL_PATH>/tools/iar/SIMPLELINK_MSP432E4_SDK.custom_argvars) in a text editor if you need to modify the default path argument variables.

• Restart IAR.

5.2 Running Your First Example / Importing Your First project
