SimpleLink ti_wisunfan Examples

This repository contains the ti_wisunfan examples for TI devices supported by the SimpleLink Low Power F2 SDK. To learn which devices are supported by the SDK, refer to the SDK Device Association section.

Repository Layout

The examples/ directory contains the same ti_wisunfan examples provided in the SDK, in the same directory structure.

The SimpleLink Low Power F2 SDK is provided as Git submodules in the cc13xx_cc26xx_sdk subdirectory.

As a quick reference, you can initialize and update a single Git submodule in one step like this:

# To initialize and update the F2 SDK
.../simplelink-ti_wisunfan-examples$ git submodule update --init cc13xx_cc26xx_sdk

Alternatively you can clone and initialize/update all submodules when cloning a repo with git clone --recurse-submodules {repo-ref}. See Git documentation for details.

Once initialized and updated, you can refer to the SDK's README.md and Release Notes for details on how to download its dependencies, and build its libraries.

Note, the links above are to online copies of the latest SDK READMEs. They are useful for online readers, but be sure to consult the SDK submodule's actual README.md after cloning, checking out your branch/tag, and updating your submodule, as details may change from release to release.

Setup Instructions

Build SDK Libraries

Each time you update an SDK submodule, you will need to build its libraries. This process can vary between the different SDKs, so refer to each SDK's README.md for specifics, but generally you will need to edit the imports.mak file at the top, then run make.

Note that sometimes the dependencies can vary from SDK to SDK. For example, if you've been using the F2 SDK and SysConfig version X, and want to start using the F3 SDK, it may require a newer SysConfig version. So, again, be sure to refer to each SDK's README.md and Release Notes.

Often newer versions of dependencies are compatible, so you can use newer-and-compatible versions than the SDK was validated against. But each SDK does have its own imports.mak so you can specify different dependency versions for each SDK if needed.

Build Examples

After building the SDK libraries, you can build the ti_wisunfan examples. The examples support two ways to build:

• CCS IDE
• IAR IDE

Build Examples From CCS

Remember, before building the examples, you must build the SDK libraries!

The examples also include TI Code Composer Studio (CCS) project support, enabling them to be imported into, and built by, CCS.

Before importing the example, the SDK(s) location must be registered with CCS:

1. Preferences->Code Composer Studio->Products
2. Select Add...
3. Navigate to the SDK submodule location
4. Select Open

Repeat for each SDK you will be using. This registers the SDK with CCS. Successful registration of an SDK will show it in the "Discovered Products" list:

If using FreeRTOS, its location must also be configured in CCS:

1. Preferences->Code Composer Studio->Build->Environment
2. Select Add...
3. Add the variable name FREERTOS_INSTALL_DIR
4. Assign it to the absolute path of your installation of FreeRTOS

Now you can import an example!

1. Project->Import CCS Project...
2. Select search-directory->Browse...
3. Navigate to a directory within your clone of the example repo to search for examples and Select Folder
4. Select the example(s) you wish to import and press Finish

======= If building with F2 SDK 7.10.01.24 you will need to install SysConfig to 1.16.2 and update the project.

1. Install SysConfig 1.16.2 (see cc13xx_cc26xx_sdk instructions)
2. Select the project to build
3. Right-click and select "Properties."
4. Under General, select Products, then SysConfig
5. Click on Edit and select 1.16.2

Build Examples from IAR

Remember, before building the examples, you must build the SDK libraries!

Follow the instructions in your respective SDK's Quick Start Guide:

• SimpleLink Low Power F2 SDK Quick Start Guide

Troubleshooting

When building on *nix platform (Linux/Mac) the library build may fail with an error similar to:

error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: Unsupported triple for mach-o cpu type: thumbv6m-ti-none-eabi

To fix, make sure the arm version of ranlib is in the path before the OS version of ranlib located in /usr/bin. Simply set the location of the gcc ARM ranlib ahead in the shell's path. Example:

$ export `PATH`=/Users/username/ti/gcc_arm_none_eabi_9_2_1/arm-none-eabi/bin:$PATH
