Application: This sample code demonstrates how to implement a USB HID composite device (Virtual COM Port and Multimedia Key).
BSP Version: M031 BSP CMSIS V3.03.000
Hardware: NuMaker-M032KI Ver1.0
A USB Composite Device is a peripheral device that supports more than one device class at the same time. This example code consists of Virtual Com port and HID media key in one USB device. The HID class is for reporting the key buttons inputs to control the mute, brightness, keyboard brightness and volume up/down of multimedia functions through the USB protocol.
