Abstract
In order to widely use the digital keyboard in industry, it weaks to solve the cost of digital keyboard hardware circuit designing and the problem of conveniences of digital keyboard modularization using. By the study of PS/2 communication protocol,using the STM32 micro controller I/O Pin 5 V tolerant function,eliminating the in-consistency of electrical level of PS/2 and STM32 , a simulation method for PS/2 communication protocol is put forward. The method that used the software algorithm programming solved data communication and function realization from keyboard to STM32. After Keil software simulation and the test and verification of instrument,the expected results are obtained.关键词
