5.6 Observe the Output

To observe the output on the board and in the serial terminal, follow these steps:

  1. To launch MPLAB® Data Visualizer, type >MPLAB: Data Visualizer in the Command Palette.

    Figure 5-24. Launch MPLAB® Data Visualizer

  2. Select the COM port corresponding to the Curiosity Nano from the Source drop-down menu in the terminal window.

  5. The on-board LED of the AVR32LA32 Curiosity Nano evaluation kit toggles at a default interval of two seconds. The LED blink interval is displayed on the serial terminal.

    • Press the SW switch on the AVR32LA32 Curiosity Nano evaluation kit to change the blink interval to 400 ms
    • Each press of the on-board switch (SW0) on the Curiosity Nano evaluation kit alternates the blink interval between 400 ms and two seconds
