User Guide DA7212 User Guide Rev1.2 DA7212 Ultra Low Power Codec and Power Commander GUI Software Introduction The DA7212 Evaluation Board has been designed to allow measurement and evaluation of the DA7212 device. All Audio Codec functionalities are self-contained within the Evaluation Board (EVB). The EVB is supplied with a USB memory stick containing various documents and a GUI to allow the user to control the DA7212. The GUI is called Power Commander. It uses a simple graphical interface, allowing the DA7212 to be controlled via a USB port of a PC. The EVB has a number of jumper links to enable the user to change the system configuration and to allow him to make appropriate measurements, although, in reality, few jumper links are required to be altered for standard operations of the DA7212.
