部分功能需要自行开放,源码完整可编译...一直珍藏的东西..希望大家拿去多多学习-CSA (stone) ... part of the package source feature requires its own open-source can compile a complete collection of things have been ... .. hope that everyone take a lot to learn

基于arduino智能计步器，用MPU6050采集加速度值，通过蓝牙串口传至手机APP中(enviroment test)

stm32驱动oled 12864，采用模拟SPI方式(Oled 12864 is drived by stm32 using the method of simulating SPI)

由于超声波指向性强，能量消耗缓慢，在介质中传播的距离较远，因而超声波经常用于距离的测量，如测距仪和物位测量仪等都可以通过超声波来实现。利用超声波检测往往比较迅速、方便、计算简单、易于做到实时控制，并且在测量精度方面能达到工业实用的要求，因此在移动机器人研制上也得到了广泛的应用。(Because of its strong directivity, slow energy consumption and long propagation distance in the medium, ultrasound is often used for distance measurement, such as range finder and level gauge, which can be achieved by ultrasound. Ultrasound detection is often fast, convenient, simple in calculation, easy to achieve real-time control, and can meet the requirements of industrial application in measurement accuracy, so it has been widely used in the development of mobile robots.)
