Running the Application

  1. Open the project with appropriate IDE. Compile the project and program the target device.

  2. Launch a terminal emulator, such as Tera Term. Select the appropriate COM port and set the serial port settings to 115200-N-1.

  3. If a USB mouse is not connected to the Host connector, the serial terminal emulator window will show the "Connect Mouse" prompt.

  4. Attach a USB mouse to the Host connector of the target hardware. Refer to the Configuring the Hardware section for any converter requirements. The message, "Mouse Connected", will display in the serial terminal emulator window.

  5. Begin moving the mouse and the appropriate relative coordinate changes for X,Y, and Z axes should be displayed in the serial terminal window.

  6. Click the mouse button to toggle LEDs on the board. Refer to the Configuring the Hardware section for details on the relevant LED.

  7. Disconnecting the mouse will result in the message, "Connect Mouse", to reappear on the serial console.
