智能小车的51单片机设计源代码，适合参加电子类竞赛和有兴趣爱好自己制作小的玩具作品。全部程序调试通过，没有任何问题。(Smart car 51 single design source code for contests and participate in electronic hobbies to produce their own little toy works. All program debugging through without any problems.)

摘 要 电机转速是电机的一个极为重要的状态参数 文中介绍了几种基本的电机转速测量 方法 并对这些测量方法进行了比较 给出了基于加速度计进行电机转速测量的硬件电路设 计方法和测试系统的工作原理(Summary of the motor speed is an extremely important motor state parameters paper describes several basic motor speed measurement methods and these measurements were compared based on accelerometer gives the motor speed measurement hardware circuit design and test systems Works)

Very hard to find Texas Instruments software (ADP.exe) for calculating circular and rectangular coils for RFID application (13.56Mhz and 125kHz). Software is very accurate. Software is 16-bit, so it must be run on Windows XP (not compatible with Windows 7)

采用压力传感器实现重量信号采集，然后就给放大滤波后送给A/D，经单片机进行数据处理，LCD作为显示(The pressure sensor achieve weight signal acquisition, and then to enlarge filtered gave A/D, SCM data processing, LCD as display)

三轴加速度传感器ADXL345的驱动程序,基于STM32F4.(Triaxial accelerometer ADXL345 drivers, based STM32F4.)

多功能数字电表，能实现量程自动切换，液晶显示(Multi-function digital meter, to achieve automatic range switching, LCD)

说明：  基于stm32单片机电压表设计,AD检测分压电阻电压值，根据电阻分压比算出所测电压，并显示在oled液晶上(Based on the design of voltage meter of STM32 single chip computer, AD detects the voltage value of dividing resistor, calculates the measured voltage according to the ratio of dividing resistor voltage, and displays it on OLED liquid crystal.)

SSD1306的OLED上显示字符、汉字、画点、画线、画圆的驱动函数，以及一个基于MSP430单片机的各个功能的测试文件。 整个文件采用模块化的划分方式，程序清晰容易阅读，适用于对OLED不熟悉的初学者直接移植使用，非常方便。(SSD1306 OLED display characters, Chinese characters, painting, line drawing, Circle Drive function, and one each function based on MSP430 single chip microcomputer test file. The entire file by dividing the modular, procedures clear and easy to read, suitable for beginners unfamiliar with OLED transplanted directly use, very convenient.)

基于51单片机，芯片stc89c52,使用PCF8591ad转换器的源代码(Based on 51 MCU, chip stc89c52, using PCF8591ad converter source code)

高压直流输电发电机模型，有参考价值，做的挺不错(HVDC generator model, a reference value, doing pretty good)
