USB common definitions (Driver_USB.h)
The Universal Serial Bus (USB) implements a serial bus for data exchange. It is a host controlled, plug-and-play interface between a USB host and USB devices using a tiered star topology. In microcontroller (MCU) applications, the interface is often used to connect a device to a host for data exchange or control purposes.
Block Diagram
Typically only one USB Device is connected to a USB Host. If several USB devices must be connected to the same USB host, then the connection must be done via a USB hub.
USB API
The following header files define the Application Programming Interface (API) for the USB interface:
The driver implementation is a typical part of the Device Family Pack (DFP) that supports the peripherals of the microcontroller family.
Driver Functions
The driver functions are published in the access struct as explained in Common Driver Functions
