USB-Powered Application

This use case will show you how to make use of the USB "pass-through" connectors on the Power Debugger. We will
use a SAM L21 Xplained Pro kit as an example of a USB-powered product, where the designer is interested in both
total power consumed over the USB port and that consumed by the target device on the board. The SAM L22 kit
could also be used.
Important: The Data Visualizer used in this use case should not be confused with the MPLAB Data
Visualizer. These two applications have a similar feature set and the Power Debugger also works with the
MPLAB Data Visualizer, but the user interface is totally different. The Data Visualizer referred to in this use
case was originally named Atmel Data Visualizer.
3.2.1 Requirements
To be able to work through this example, the following is required:
• Host computer with Atmel Studio 7 (or later) installed (Data Visualizer is included)
• Microchip Power Debugger Kit (cabling included)
• Microchip ATSAM L21 Xplained Pro Kit, or similar target board with USB device connector, external
programming header, and current measurement header
