一个水轮机调速的控制程序，想从事控制方面程序设计的朋友可以参考一下。(a turbine governor control procedures to control in the design process can make reference to a friend.)

2.4g和FM（72MHZ，40MHZ，35MHZ……）是个啥信号波，就是我们的控制内容，手拿遥控器推一推摇杆，信号波的频率就会改变(2.4g and FM (72MHZ, 40MHZ, 35MHZ ......) is Gesha signal wave is our control content, holding the remote control push, rocker, will change the frequency of the signal wave)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)

说明：  本课题对基于单片机的交通灯控制系统进行设计。以MCS-51系列单片机为控制核心，设计并制作交通灯控制系统，用于十字路口的车辆及行人的交通管理。东西南北四个路口具有左拐、右拐、直行及行人4种通行指示灯，并分别用计时器显示路口通行转换剩余时间，在特种车辆如119、120通过路口时，系统可自动转为特种车辆放行，其他车辆禁止通行状态。(Traffic light control system based on SCM (Single Chip Microcomputer) is designed in this paper. System requires that MCS-51 series SCM is used as CPU. Traffic light control system should be designed and made .There are four groups light which indicate to turn left, turn right, and go straight ahead and pedestrian access in east, west, north and south four directions. Timer shows traffic conversion remainder time. When special vehicles, such as 119,120 go through, the system can automatically allow special vehicles running and other vehicles is prohibited.)

这是用c语言写的利用扬声器放歌的程序,可以编译一下就可使用(useful)

WM8731是高性能的音频编码解码芯片，使用时需要通过IIC总线进行配置，本程序可以直观的设置各寄存器的参数，并自动生成C或C++语言代码。使用方便。(WM8731 is a high-performance audio codec chip, need to use IIC bus configuration, this procedure can be intuitively set the parameters of the register, and automatically generate C or C++ language code. Easy to use.)

avrmega16的频率计源码，在2m以内误差为1-3hz，1602显示(avrmega16 the frequency of source, in less than 2m error 1-3hz, 1602 show)
