A multi-channel programmable ps2 interface UAV system key decoder

Abstract

The present invention relates to an unmanned aerial vehicle system key decoder with multichannel programmable PS2 interfaces. The key decoder comprises a key interface circuit, an instruction decoder circuit, an instruction receiving circuit, a data return circuit, a key code storage circuit and a plurality of PS2 interface circuits. The key decoder uses a minimum application system with a single-chip microcomputer as a core, so that key code information corresponding to a key can be changed through an instruction. The key decoder is applicable to non-coded independent keys and matrix keys, and has a function of changing the key code of the key. In addition, the key decoder has a design of multiple PS2 interfaces, so that a single group of keys controls a single computer and a single group of keys controls multiple computers simultaneously, therefore, the key decoder meets the requirement of the unmanned aerial vehicle system of controlling multiple computers.

Description

technical field [0001] The invention belongs to the unmanned aerial vehicle electronic technology, and relates to a multi-channel programmable PS2 key decoding device for an unmanned aerial vehicle system. Background technique [0002] The key decoder is to convert non-coded independent keys or matrix keys into standard keys with multiple PS2 interfaces [0003] Disk devices can be used in many fields such as industrial control, video surveillance, and unmanned aerial systems. At present, the known key decoding devices are all special equipment for solidifying the key codes of the keys, and cannot change the key code values ​​of the keys according to the use requirements. When applying to new use requirements, the key decoding equipment needs to be redesigned, so Does not have the characteristics of generalization. The known patents (patents 200610132019.7 and 200510100145.X) are used for key recognition of embedded system devices (such as mobile phones), which cannot be d...
