Abstract

The invention relates to a system and method for expanding peripheral interfaces of an intelligent terminal. According to the system and method, an embedded integrated circuit and a USB-HUB expanding unit are adopted and through circuit debugging and software programming and under the condition that the system and the interfaces of the intelligent terminal are not changed at all, the system and method for expanding the peripheral interfaces of the intelligent terminal through USB interfaces are developed. According to the scheme, a standard USB-OTG protocol on the standard intelligent terminal is adopted and the expansion interfaces are communicated with the intelligent terminal in the mode of a USB-HID device, so that difficulty of secondary development of the intelligent terminal is greatly lowered, the speed of secondary development is increased, customization cost of the intelligent terminal is saved, and product cost is reduced.

Description

technical field [0001] The invention relates to a USB-OTG interface expansion system and method for a mobile intelligent operating system, especially a system and method for expanding other interfaces such as a UART interface, an SPI interface and an I2C interface using an integrated circuit design and software programming using a USB interface. Background technique [0002] USB OTG is the abbreviation of USB On-The-Go. It is a technology developed in recent years. It was announced by USB Implementers Forum on December 18, 2001. It is mainly used in the connection between various devices or mobile devices for data exchange. Especially PDAs, mobile phones, consumer devices. Change the inconvenience of data exchange between multiple connectors of different standards among devices such as digital cameras, video cameras, printers, and memory cards of up to 7 standards. The development of USB technology enables PCs and peripheral devices to connect various devices together in a ...
