说明：  超声波测量电路设计利用超声波来实现距离、速度、流量、浓度等的检测 ,具有其他检测方法无法比拟的显 优点。(Using ultrasonic ultrasonic measuring circuit to achieve distance, speed, flow, concentration of detection, other detection methods have significant advantages unmatched.)

There is an increasing demand today for motor control circuits, as a result of the incredible proliferation of automated position control equipment, which is itself made possible by recent developments in the field of digital computation.

用c8051f320单片机,任选两个IO口进行模拟IIC操做,用软件IIC对加速度芯片MXC6020进行读写操作(IIC接口)(With c8051f320 Singlechip, optional two IO simulation IIC mouth fuck to do with software acceleration chip IIC on MXC6020 to read and write operations (IIC interface))

本源码程序为射频通信驱动代码，采用IAR system软件开发，以MSP430单片机为主控芯片，程序集成了CC1120，CC1200，CC1101等多种射频芯片，在使用时可通过用户自己屏蔽不需要的芯片，程序中均已文件分好，各种芯片的代码互不干扰。我已经通过测试，改程序可以直接运行，但用户在使用时需进行IAR软件的路径配置(The source program for RF communication driver code, using the IAR system software development, MSP430 single chip as the main control chip, the program integrates CC1120, CC1200, CC1101 and other radio frequency chip, by the users themselves do not shield chip when in use, the program have the good, various chip code do not interfere with each other. I have passed the test, reform program can be run directly, but the path to configure user required when using IAR software )

说明：  该源代码为基于AVR单片机的温度加热控制系统的源程序。测温采用的的是热敏电阻，加热控制采用的是PID算法。另：编译器我用的是CVAVR 版本号是1.25.7a(The source code for AVR-based single-chip temperature heating control system of the source. Temperature measurement is used in thermistor, heating control PID algorithm is used. The other: the compiler I use is CVAVR version 1.25.7a)

超声波测距，在51单片机内核下的超声波测距程序，比较精简，希望大家受用。(Ultrasonic ranging, in 51 single kernel of ultrasonic distance measurement procedures, more streamlining, I hope everyone is good enough.)
