MSP430F149_PS2_keyboard_SN74LVC4245
- 本程序使用MSP430F149驱动PS2接口的PC键盘，使用了SN74LVC4245用作电平转换；PS2 端口使用了标准的六芯插座，可以接收来自标准键盘、鼠标的数据。由于键盘、鼠标都是 5V 供电系统，而 MSP430F149 只能工作在 3.3V，所以需要在两者之间进行电平转换。根据键盘的工作原理，MCU只要接收键盘发送过来的时钟信号和数据信号，然后对数据信号进行解码就可以了。为此我们利用了电平转换电路的两根数据线，让键盘的时钟线 CLK 连接SN74LVC4245 的A8 端口，键盘的数据线
C51
- 由8051组成的单片机系统通常情况下，P0口分时复用作为地址、数据总线，P2口提供A15-A8即高8位地址，P3口用作第二功能，只有P1口通常用作I/0口。P1口是8位准双向口，它的每一位都可独立地定义为输入或输出，因此既可作为8位的并行I/O口，也可作为8位的输入输出端。当工作在输入方式时，对应位的锁存器必须先置1,才能正确地读到引脚上的信号,否则,执行读引脚指令时,若对应位的锁存器的值为0，读的结果永远为0。
