PS2 controller suitable for long-distance transmission and implementation method

Abstract

The invention discloses a PS2 controller suitable for long-distance transmission and an implementation method. The controller packages a master device interface module to form a slave core control unit, and packages a slave device interface module to form a master core control unit. Interface communication state monitoring and error checking are carried out, and abnormal information of a slave device end is filtered; and information encoding, decoding and checking, that is, uniform encoding, transmitting and decoding are carried out on the decoding information, the interface state informationand the data checking information to ensure normal communication under the condition of unstable transmission link or stronger interference. The controller is connected with master equipment on the upper portion and slave equipment on the lower portion, master-slave equipment interface time sequence control is achieved, standard PS2 protocol communication is supported, and basic guarantee is provided for long-distance transmission of the PS2 equipment. The master-slave control unit is designed to be modularized, communication data are processed in parallel, and the design readability and the secondary development value are enhanced to a certain extent. The controller encodes, decodes and transmits the communication data and checks the data, so that the stability and the anti-interference performance of the controller are enhanced.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of computers, and in particular relates to a PS2 controller suitable for long-distance transmission and a realization method. [0003] 【Background technique】 [0004] Due to the limitation of signal transmission in the communication process of the traditional PS2 interface, the longest control distance of the external input device is less than 3 meters, which cannot meet the development needs of computer remote control. At present, most of the solutions used by products on the market rely on single-chip microcomputers or PS2 dedicated controllers to complete PS2 interface signal reception, transmission and long-distance transmission. Its anti-interference, reliability, and stability are poor. In the secondary development process, it is difficult to transplant, and the interface adaptability is low, and it cannot match and meet various needs. [0005] 【Content of invention】 [0006] The object of the present ...
