Abstract

The present invention provides a USB OTG device, an electronic device and a method for realizing the OTG function. The USB OTG device includes: a USB host module, an OTG module, a USB peripheral module, and a relative USB host module, an OTG module and a USB peripheral module. Independently set USB controller driver module; USB host module, used to provide functional support of USB host side for OTG function; USB peripheral module, used to provide functional support of USB peripheral side for OTG function; OTG module, used based on USB The function support of the host module and the USB peripheral module realizes the OTG function; the USB controller driver module is used to provide the controller driver for the realization of the OTG function. The technical scheme of the present invention can increase the modifiability of the OTG function and reduce the complexity of implementing the OTG function on different USB controllers.

Description

technical field [0001] The invention relates to communication technology, in particular to a USB OTG device, electronic equipment and a method for realizing OTG functions. Background technique [0002] The Universal Serial Bus (Universal Serial Bus, referred to as USB) is a general interface for data exchange. The Universal Serial Bus Implementers Forum (Universal Serial Bus Implementers Forums, referred to as USBIF) has developed the USBOTG (On-The-Go) specification, and the USBOTG specification is USB2. 0 specification, an OTG product is a portable device that uses a single dual-role receptacle (Mini-AB receptacle or Micro-AB receptacle, not another USB receptacle). When an OTG-supporting device is connected to an ordinary USB device, the OTG-supporting device acts as the host, and the ordinary USB device acts as a peripheral; when two OTG-supporting devices are connected, the plugs at both ends of the USB cable (A-plug and B- plug) to distinguish between the default host...
