[Edge Impulse CLI](/tools/clis/edge-impulse-cli/installation) 2. [Segger JLink](https://www.segger.com/downloads/jlink/) **Problems installing the CLI?** See the [Installation and troubleshooting](/tools/clis/edge-impulse-cli/installation) guide. ### Connecting the Apollo 5 Audio Add-on Board (Models with Audio Input Only) This step is only needed when using models requiring microphone input, such as the example below. Skip this section if you are testing other models that do not need audio input. Connect the microphone board to the Apollo510-EVB as shown below.

Skip this section if you are testing other models that do not need camera input. The [ArduCam Mega 5MP SPI](https://www.arducam.com/product/presale-mega-5mp-color-rolling-shutter-camera-module-with-autofocus-lens-for-any-microcontroller/) connects to the Apollo510-EVB pins as shown in the table below: | Camera Pin | EVB Pin | | - | - | | GND | Any EVB GND | | 5V/VDD | Any EVB 5V | | SCK | Pin 47 | | MISO | Pin 49 | | MOSI | Pin 48 | | CS | Pin 60 | ArduCam Mega 5MP SPI camera wired to the Apollo510 evaluation board **The wiring harness provided with the camera can be sensitive, so pin jumpers or another wiring harness may help** ### Flashing pre-built firmware Pre-built image with only audio support and "Hello World" detector example [here](https://cdn.edgeimpulse.com/build-system/firmware-ambiq-apollo510-audio.zip) Get started by extracting the archive and choose the appropriate script for your system architecture to flash the firmware: Terminal window running the Apollo5 firmware flashing script ## Connecting to Edge Impulse ### Using the daemon From a command prompt or terminal, run: ``` edge-impulse-daemon ``` 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 `--clean`. Alternatively, you can access the project API Key as shown below by navigating to the **Dashboard** section on the left pane of your Studio project and select the **Keys** tab, then click the copy/paste icon next to the API Key to copy the entire text to your clipboard, then run: ``` edge-impulse-daemon --api-key [paste your key here] ``` Project dashboard Keys tab with the API key copy control highlighted ### Connecting to Studio Run the `edge-impulse-daemon` and connect to your project, you will be prompted to name your device: Terminal wizard connecting the Apollo5 board to an Edge Impulse project That's all! Your device is now connected to Edge Impulse. To verify this, go to [your Edge Impulse project](https://studio.edgeimpulse.com/studio/profile/projects), and click **Devices**. The device will be listed here. Devices page listing the connected Apollo5 evaluation board ### Collecting data #### Audio With the device connected to Studio, you can use it to collect audio data up to 5 seconds in length for training and testing your model. Navigate to the Data acquisition tab and start collecting samples: Data acquisition page configured to collect an audio sample Daemon output during sampling: Terminal output while collecting an audio sample from the Apollo5 board
Audio sample view with waveform collected from the Apollo5 board ##### Video Data acquisition page configured to collect an image sample Sampling images: Camera feed frames being ingested from the Apollo5 board Three supported sizes 96x96, 128x128, 160x160: Image sample previews collected at the supported camera sizes ## Next steps: building a machine learning model With everything set up you can now build your first machine learning model with these tutorials: * [Recognizing sounds from audio](/tutorials/end-to-end/sound-recognition) * [Keyword spotting](/tutorials/end-to-end/keyword-spotting) * [Detecting objects with FOMO](/tutorials/end-to-end/object-detection-centroids) ### Example project Start by going to [your Studio projects](https://studio.edgeimpulse.com/studio/profile/projects) then create a new project and navigate to the `Create impulse` section of `Impulse design`, at which point you will be prompted to select your target, choose the Apollo5: Create impulse page with Apollo5 selected as the target hardware Then add the DSP block: Impulse design page with an audio processing block added Then the keyword spotting learn block: Impulse design page with a keyword spotting learning block added And finally save the impulse: Saved impulse showing audio input, processing, and keyword spotting blocks #### Processing Now select the DSP block: Impulse design sidebar with the DSP block selected And go to `Generate features`: Generate features page for the Apollo5 example project Click the button and wait for the job to finish, when it does you'll see something like this: Feature explorer showing generated DSP features for the Apollo5 example project #### Training Select the learning block: Impulse design sidebar with the learning block selected Then click `Save & train` and you'll eventually see an output like this: Training output for the Apollo5 keyword spotting model #### Testing Go to the `Model testing` section and enable int8 testing: Model testing page with int8 testing enabled And run the test: Model testing results for the trained Apollo5 model #### Deploying Navigate to the `Deployment` section and choose the **Apollo 5**: Deployment page with Apollo5 selected Now click `Build` and wait for the job to finish, when it does a zip archive will be downloaded to your computer. #### Flashing See the previous section on flashing the board. #### Running the impulse You can run your impulse by using `edge-impulse-run-impulse`: Terminal output from edge-impulse-run-impulse on the Apollo5 board ## Troubleshooting If you have problems with the flashing script make sure you are using USB cables with data and not just power-only cables.
