Hello, i am new to LPC1768 and also in USB development. i want to send some text or textual data from my computer (working as host) to USB device on LPC1768 and vice versa. Please guide me how to start my development. I have read about the USB functionality. I have come to know about the classes that is used for development like Audio, HID etc,
i think that in my case USB CDC is best. Please guide me how to write the CDC Class. I have used the example that come up with LPC1768 but its not connecting with my computer as driver not installed successfully. Please Help me Thanks in advance
