Connect the application to a USB host (e.g.Connect the USART peripheral to the USART interface of the board.When connected to a USB host system this application allows to display all available memories as a removable disks and provides a mouse in the Unix/Mac/Windows operating systems. After loading firmware, connect the board (EVKxx,Xplain.) to the USB Host.
And, the example uses the buttons or sensors available on the board to simulate a standard mouse, keyboard. Also, the example is a bridge between a USART from the main MCU and the USB CDC interface. The example uses all memories available on the board and connects these to USB Device Mass Storage stack. For example, a CDC device can appear as a virtual COM port, which greatly simplifies application development on the host side. While a CDC device enables the implementation of quite complex devices, it can also be used as a very simple method for communication on the USB. This class makes it possible to connect communication devices such as digital telephones or analog modems, as well as networking devices like ADSL or Cable modems. The Communication Device Class (CDC) is a general-purpose way to enable all types of communications on the Universal Serial Bus (USB). This example shows how to implement a USB Composite Device with HID mouse, keyboard, CDC and Mass Storage interfaces on Atmel MCU with USB module.ĭescription of the Communication Device Class (CDC)
