Abstract

The invention discloses a digital electronic scale matrix keyboard simulator, which comprises a simulation module connected with an electronic scale matrix keyboard. The simulation module is connectedwith a PC; the simulation module comprises an MCU, four simulation switch chips and an external clock are connected to the MCU, the MCU is connected with the PC, and the electronic scale matrix keyboard is connected with the MCU. The digital electronic scale matrix keyboard simulator is adopted to simulate an electronic scale matrix keyboard, and two processes of key learning and key input are included. The digital electronic scale matrix keyboard simulator can effectively improve the typing efficiency of a cheating code sequence. The invention also provides a digital electronic scale matrixkeyboard simulation method.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a digital electronic scale matrix keyboard simulator, and also relates to a digital electronic scale matrix keyboard simulation method. Background technique [0002] At present, due to the characteristics of low cost and simple structure, electronic scales are easy to be converted into cheating scales, and are frequently used in bazaars. Relevant measurement units must continuously input possible cheating code sequences to detect whether they are cheating or not. Time-consuming. Therefore, the present invention has designed a kind of equipment that can simulate input by computer, can effectively improve the typing efficiency of cheating code sequence. Contents of the invention [0003] The purpose of the present invention is to provide a digital electronic scale matrix keyboard simulator, which can effectively improve the typing efficiency of cheat code sequences...
