The Texas Instruments CC1352P LaunchPad is a development board equipped with the multiprotocol wireless CC1352P microcontroller. The LaunchPad, when paired with the BOOSTXL-SENSORS and CC3200AUDBOOST BoosterPacks, is fully supported by Edge Impulse, and is able to sample accelerometer & microphone data, build models, and deploy directly to the device without any programming required. The CC1352P Launchpad, BOOSTXL-SENSORS, and CC3200AUDBOOST boards are available for purchase directly from Texas Instruments.
If you don't have either BoosterPack or are using different sensing hardware, you can use the Data forwarder to capture data from any other sensor type, and then follow the Running your impulse locally tutorial to run your impulse. Or, you can clone and modify the open source firmware-ti-launchxl project on GitHub.
To set this device up in Edge Impulse, you will need to install the following software:
- Edge Impulse CLI.
- Texas Instruments UniFlash
- On Linux:
- GNU Screen: install for example via
sudo apt install screen.
- GNU Screen: install for example via
Problems installing the Edge Impulse CLI?
See the Installation and troubleshooting guide.
With all the software in place it's time to connect the development board to Edge Impulse.
Before you start: The LaunchPad jumpers should be in their original configuration out of the box
If you have already modified the jumper connections, see the LaunchPad's User Guide for the original configuration.
The Sensor BoosterPack enables accelerometer based data collection and inferencing. To connect, orient the sensor board such that the 3V3 and GND markings line up with the LaunchPad as shown below.
The Audio BoosterPack enables microphone based data collection and inferencing. To connect, follow the TI Quick Start Guide for the CC13x2P to properly interface the audio BoosterPack with the LaunchPad.
Both BoosterPacks may be connected to the LaunchPad at the same time!
To do this, connect the BOOSTXL-SENSORS board first, and then follow the same TI Quick Start Guide for the CC3200AUDBOOST. You'll interface the audio board with the header pins of the sensor board rather than the LaunchPad, such that the boards are stacked together as shown below.
Use a micro-USB cable to connect the development board to your computer.
The development board does not come with the right firmware yet. To update the firmware:
- Download the latest Edge Impulse firmware, and unzip the file.
- Open the flash script for your operating system (
flash_linux.sh) to flash the firmware.
- Wait until flashing is complete, and press the RESET button once to launch the new firmware.
Problems flashing firmware onto the LaunchPad?
See the Troubleshooting section for more information.
From a command prompt or terminal, run:
This will start a wizard which will ask you to log in, and choose an Edge Impulse project. If you want to switch projects run the command with
Which device do you want to connect to?
The TI LaunchPad enumerates two serial ports. The first is the Application/User UART, which the edge-impulse firmware communicates through. The other is an Auxiliary Data Port, which is unused.
When running the
edge-impulse-daemonyou will be prompted on which serial port to connect to. On Mac & Linux, this will appear as:
? Which device do you want to connect to? (Use arrow keys) ❯ /dev/tty.usbmodemL42003QP1 (Texas Instruments) /dev/tty.usbmodemL42003QP4 (Texas Instruments)
Generally, select the lower numbered serial port. This usually corresponds with the Application/User UART. On Windows, the serial port may also be verified in the Device Manager
If a selected serial port fails to connect. Test the other port before checking troubleshooting for other common issues.
Alternatively, recent versions of Google Chrome and Microsoft Edge can collect data directly from your development board, without the need for the Edge Impulse CLI. See this blog post for more information.
That's all! Your device is now connected to Edge Impulse. To verify this, go to your Edge Impulse project, and click Devices. The device will be listed here.
With everything set up you can now build your first machine learning model with these tutorials:
You can also test out a pre-loaded model, included with the Edge Impulse firmware, right away! Just close the
edge-impulse-daemon and run
If the UniFlash CLI is not added to your PATH, the install scripts will fail. To fix this, add the installation directory of UniFlash (example
/Applications/ti/uniflash_6.4.0 on macOS) to your PATH on:
If during flashing you encounter further issues, ensure:
- The device is properly connected and/or the cable is not damaged.
- You have the proper permissions to access the USB device and run scripts. On macOS you can manually approve blocked scripts via
System Preferences->Security Settings->Unlock Icon
- If on Linux you may want to try copying tools/71-ti-permissions.rules to /etc/udev/rules.d/. Then re-attach the USB cable and try again.
gcc/build/edge-impulse-standalone.out binary file may be flashed to the LaunchPad using the UniFlash GUI or web-app. See the Texas Instruments Quick Start Guide for more info.
