• XMEGA-A3BU Xplained

Description of the demo application

This demo is a simple program for measuring the current consumption of XMEGA Xplained boards. The demo initializes the device for low power consumption, and cycles through all sleep modes when any switch is pressed. The current consumption of the device can be measured with an ammeter connected between the pins VCC_P3V3 and VCC_MCU_P3V3 on the board after the jumper has been removed.
