51微控制器的P1口是一个准双向口,作通用的I/O口使用,就是将P1口分别作为输入和输出进行练习。
作输入时,把开关作为输入装置,由P1口读取开关状态。作输出时,控制LED发光二极管。
-P1 51 microcontroller is a quasi-bidirectional port for general I/O port to use, the experiment is to P1, respectively, as input and output ports to practice. As input, the switch as an input device, read the switch status from the P1 port. For output, the control LED light-emitting diodes.
