基于KEIL平台开发的红外循迹，超声波避障智能小车程序(Infrared Track and Ultrasound Barrier Avoidance Intelligent Car Program Based on KEIL Platform)

说明：  主控cpu采用stm32f407vet6,采用口线模拟的spi总线来采集ads1118的俩路输入模拟信号。信号输入范围为0--2.048V。对应0--65535.(The main control cpu adopts stm32f407vet6, and adopts the spi bus of port line simulation to collect the two input analog signals of ads1118. The signal input range is 0--2.048V. Corresponds to 0--65535.)

超精简的读写u盘程序，只有180行，可生成文件系统，估计再没有比这更短的程序了把？(Super-streamlined procedures to read and write u disk, only 180 lines, can generate the file system, it is estimated that more There is nothing short of the procedures?)

说明：  介绍了一种用加速度传感器测量振动位移信号的方法。 该方法采用频谱转换法，首先将加速度谱转换成位移谱，再计算出位移谱中每个频率分量对应的幅值 、圆频率和初相角，最后对各位移分量进行叠加得到振动位移的时间历程。 验证试验结果表 明该方法 可行 ， 精度可满足工程 实践的需要 。(A method of measuring vibration displacement signal with acceleration sensor is introduced. In this method, the acceleration spectrum is first converted into displacement spectrum, and then the corresponding amplitude, circular frequency and initial phase angle of each frequency component in the displacement spectrum are calculated. Finally, the time history of the vibration displacement is obtained by superimposing each frequency component. The test results show that the method is feasible and the accuracy can meet the needs of Engineering practice.)

在实现流水灯闪烁在proteus8.6使用的单片机是STM32F103R6(realize led SCM STM32F103R6 is used in Proteus 8.6 to realize pipeline lamp flickering.)
