2.7. Matrix Demo

Matrix is an application launcher that can run the pre-built applications and demos in the SDK once Linux boots up. To run the Matrix demo on an EVM, the EVM needs to have a network connection. Please refer to “Setup Network” page for how to connect the EVM to a network.

Once the EVM is connected to a network, perform the following steps to run the Matrix demo:

  1. Open a web browser on the host PC or a phone depending on the network connection type, and enter the EVM’s IP address to the web browser address bar (http://<EVM IP address>).

  2. Click “OK” and the Matrix GUI will come up on the browser, similar to what’s shown below.

  3. Choose an application to run, for example, the LED application. Click “LED” and then “Blink LED” to go to the launching menu of the blink LED application, as shown below.

  1. Read the application description to understand what it does. Click “Run” to start the application, which in this example will blink an LED on the EVM. To look inside how the LED blink works, please refer to Blinking an LED.

    Click the arrow button at the upper right to go back to previous menu, or click the menu button to go back to the main menu, to run another application.
