| Abstract: | As communication through standard PS/2 protocol can be controlled easily, PS/2 Keyboard Interface has a promising application. In order to explain its usage, this paper has introduced PS/2 Keyboard physical Interface and its communication protocol, especially illuminated its work timing and some commands in detail. In application, the circuit of interface and communication scheme between PS/2 interface and SCM are provided, along with some procedure about communication. |
