Description

+

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:

+
    +
  • Driver_USB.h : Common definitions of the USBD and USBH interface
    • +
  • Driver_USBD.h : Driver API for USB Device Peripheral
    • +
  • Driver_USBH.h : Driver API for USB Host Peripheral
    • +
+

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
