51单片机驱动无源蜂鸣器进行音乐输出1 使用了定时器，使用C51编译(51 Microprocessor Passive buzzer for the use of music output of a timer, the use of C51 compiler)

MSP430F247 Program Example(MSP430F247 application)

刚才上传的频率计程序可能不太好，现在这个计数外部脉冲的程序，还是较好的，只是得自己从中截取出来(Just upload the program may not be a good frequency counter, and now this external pulse count procedures, or better, just get yourself out from the interception of)

说明：  利用F407进行小车的控制开发，功能包括蓝牙控制小车，DHT11测温，HC-SR04超声波测距，蜂鸣器（2只老虎），流水灯，密码，电机调试（PWM）,RTE开发模式，包含一些寄存器开发代码。(F407 was used to control and develop the car, including bluetooth control car, DHT11 temperature measurement, HC-SR04 ultrasonic ranging, buzzer (2 tigers), water light, password, motor debugging (PWM),RTE development mode, including some register development code.)

1602显示DS1302实时时钟代码程序(1602 LCD DS1302 real-time clock)

本方案是基于富士通高可靠性单片机开发的锂电池电动螺丝刀，采用直流无刷电机作为核心，配合方波驱动以及闭环控制技术，实现电动工具的可靠运行。 技术参数 1）采用日本富士通MCU，性能稳定，抗干扰强，高可靠性； 2）直流18V输入（可兼容不同锂电池10V—36V）； 3）三相霍尔直流无刷电机驱动，转速高达25000转/分； 4）采用德国英飞凌高性能MOS/IGBT，驱动功率高达800W； 5）高亮LED照明，工作时点亮，不工作时自动熄灭； 6）采用智能控制技术实现待机（不工作时）功耗为 0 消耗； 7）通过软件实现软启动，启动时间可调整，瞬间（1S）达最高速； 8）具有过流保护、堵转保护、过压欠压保护； 9）带速度设置按键、正反转按键、调速开关； (The program is based on the Fujitsu MCU development of high reliability lithium battery electric screwdriver, brushless DC motor as the core, with the square wave drive and closed-loop control technology, power tools for reliable operation.)

说明：  锁相电路是相位锁定环(Phase Locked Loop)的简称，主要由鉴相器、环路滤波、压控振荡器成 。主要是要掌握LabVIEW图形化编程特点，(PLL circuit is phase-locked loop (Phase Locked Loop) for short, mainly by the phase detector, loop filter, VCO into. Mainly to grasp the features of LabVIEW graphical programming,)

说明：  通过STM32实现读取ADS1118采集的电压值(Read the voltage value collected by ads1118)
