Audio interface-based data transmission method between intelligent terminal and operating handle

Abstract

The invention discloses an audio interface-based data transmission method between an intelligent terminal and an operating handle. The data transmission method specifically comprises the following steps: receiving a key value signal emitted by the operating handle to be packed into a data frame; coding the data frame into a differential Manchester analog signal according to a specific serial communication protocol to be transmitted to an audio interface of the intelligent terminal; converting the received differential Manchester signal into a handle key value signal by the intelligent terminal to control an executed game; when an instruction is transmitted to the operating handle by the intelligent terminal, coding the instruction into the differential Manchester analog signal to be transmitted to the operating handle; and executing the instruction emitted by the intelligent terminal after decoding the received differential Manchester signal by the operating handle. The data transmission method is based on the audio interface of the intelligent terminal, realizes data transmission between each intelligent terminal and the game operating handle, is low in development cost, has high universality and guarantees the stability of data transmission.

Description

Technical field [0001] The invention relates to a data transmission technology for an intelligent terminal, in particular to a general data transmission technology for an intelligent terminal based on an audio interface. Background technique [0002] With the popularization of smart phones and various smart terminals, especially the emergence of 3G smart phones, the operating systems such as iPhone and Android embedded in smart phones are more powerful. The application functions of smart phones have long gone beyond the scope of telephone communication. The development of this kind of mobile application fully embodies the advantages of smart phones. Among them, mobile games are an extremely important form of entertainment. The current operation of mobile games is only based on touch screen operation. The control mode of this game is simple and cannot be truly reflected. The joy of playing games. Controlling mobile games through the control handle meets the needs of the majority ...

Problems solved by technology

The current problem is that the data interfaces of various mobile phone manufacturers are different, and it is difficult for external devices to be compatible one by one; some manufacturers restrict the opening of data interfaces for various commercial purposes, or charge high authorization fees; Dominant mobile phone manufacturers also have strict qualification requirements for peripheral manufacturers, artificially increasing the entry barrier

All kinds of restrictions make the development of external devices of mobile phones difficult and costly

The second type, the bluetooth transmission mode, for applications such as handle control with high real-time response requirements, inevitably has delays. In addition, the hardware cost of bluetooth is relatively high, and the poor reliability of bluetooth pairing is also an important obstacle affecting user experience.
