| Abstract: | The PS/2 protocol is analyzed in the paper.The standard scan code set 2 and command set of PS/2 keyboard are also introduced.Besides,the hardware connection of PS/2 keyboard to MCU,and it's driver programmed by Keil C51 language are given.the driver realize the support of the PS/2 standard 104 keyboard in MCU system.The driver can be used in other MCU system or embedded system easily.It is benificial to use PS/2 keyboard in the MCU application system or embedded application system. |
