PS2键盘是当今PC机最常用的种类， 基于verilog hdl 语言的ps2 通信代码-PS2 keyboard is today the most common types of PC-based communications verilog hdl code language ps2

此代码实现的是使用tms320f2812的外部中断，对应ps2键盘扫描，当检验到键盘GPIO口电平发生变化时发生中断，开发环境为CCS。-This code is to use an external interrupt tms320f2812 corresponding ps2 keyboard scan Occurs when the keyboard GPIO port level changes to interrupt testing and development environme
