单片机串口程序，可以通过keil编译，实现一台主机和多台从机的通信，从机挂接同一条总线,主机对通信有决定权 -MCU procedures, Keil compiler can achieve a host and multiple communications from the plane, from the plane with an articulated bus, the mainframe has the right to decide Communications

实现STC89LE516AD单片机的A/D转换功能，时钟11.0592M，转换结果以16进制输出到串行口，可用串行口调试程序并观察输出结果，注解非常详细。-Achieve STC89LE516AD MCU A/D conversion clock 11.0592M, conversion results to 16 hexadecimal output to the serial port, serial port can be used to debug programs and observe the output, very detailed comments.

设计一个允许n个进程并发运行的进程管理模拟系统。该系统包括有简单的进程控制、同步与通讯机构，其进程调度算法可任意选择。每个进程用一个PCB表示，其内容根据具体情况设置。各进程之间有一定的同步关系（可选）。系统在运行过程中应能显示或打印各进程的状态及有关参数的变化情况，以便观察诸进程的运行过程及系统的管理过程。-N the design of a permit to run a process complicated by the process management simulation system. The system has a simple process control, synchronization and communication agencies, the process scheduling algorithm can be arbitrary choice. Each process of a PCB said that its content in accordance with the specific circumstances of settings. The process has a certain degree of synchronization between the relationship between the (optional). System in the running process should be able to display or print the status of the process and the relevant parameters in order to observe the operation of various process and systems management processes.
