该源码是一个MicroChip的MPLAB工程。其中last.c为源码。这个程序实现了串口通信，IIC 通信以及基本的IO控制。串口可实现与PDA通信，IIC实现的是温度测量。并且通过IO口实现对直流电机的控制。-The source is a MicroChip the MPLAB project. Last.c for which source code. This procedure achieved a serial communication, IIC communications, as well as control of the basic IO. PDA serial communication can be achieved with, IIC temperature measurement is achieved. IO mouth through the realization of the control of DC motor.
