Abstract

The invention provides an instrument special keyboard based on a single-chip microcomputer and a working method thereof. The instrument special keyboard comprises a single-chip microcomputer core processing module, a matrix keyboard module and a keyboard rotary encoder module, wherein the single-chip microcomputer core processing module loads a port pull-up resistor, has an ISP and serial downloading function and carries out analysis on commands; the matrix keyboard module is composed of a plurality of key values and matched with bottom driving and control commands to achieve various functions; the keyboard rotary encoder module has a function of rapidly inputting numerical data and performing rapid selection and performs uploading operation on information. According to the instrument special keyboard based on the single-chip microcomputer and the working method, a flexible keyboard design part can be achieved; the function of rapid inputting and data selection is achieved, and keyboard self-defining convenience and universality are improved.

Description

technical field [0001] The invention relates to the field of instrument keyboard control, in particular to a keyboard control applied to radio frequency index testing of wireless terminals, and a main input device for building an instrument automatic test platform. Background technique [0002] The instrument keyboard is controlled by a single-chip microcomputer, which automatically completes handshaking, sending, receiving, data processing and output to the host computer. It is mainly used as the basic input device of the instrumented control platform of the switching unit. [0003] The keyboard design in the prior art is mainly a standard keyboard with 102 / 104 keys, and there are few special keyboards produced according to different instrument design requirements, and the standard keyboard is limited to a large extent, and it is not easy to carry out secondary development. In today's communication test field, the increasingly complex index tests require engineers to custom...
