The USB demos running on the evaluation board consist of USB host, OTG demos, and USB Device demos. The OTG demo allows two Evaluation boards to be connected together. The Host demos allow the evaluation board to be connected to a USB device, while the Device demos allow the Board to be connected to a USB host such as a computer. The user interface is managed through the board’s LCD touchscreen. The files can be stored on the USB device or on an SD Card.
