3.2 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.
