电场，考虑电导率，电流密度矢量关系式变化关系(Electric field, considering the electric conductivity, the current density variation of the relation vector)

程序是基于STM32F103ZET6实现舵机调试，源码可以实现用户给指定角度，然后舵机转到相应角度(Procedure is based servo STM32F103ZET6 achieve debugging, source code may be implemented for the user to specify the angle, and steering angle corresponding to)

STM8L101F3数码管显示_追梦效果_跑马灯——模拟SPI比如：数码管显示可以从0跑到9，也可以从9跑到0；可以在数码管外跑圈圈等等!实用于做实验等等

说明：  it`s a examples about Keil

0.我使用的是F103VET6，但软件IIC原理都是一样的，改引脚配置后可方便移植 1.连接引脚前，可以只连接VCC和GND查看模块当前地址：模块上的LED指示灯会渐亮，然后就是快闪(1)和慢闪(0)，将值记录下来，用计算器转换一下就是当前的地址值了(0. I use F103VET6, but the principle of software IIC is the same, pin configuration can be easily transplanted. 1. Before connecting pins, you can only connect VCC and GND to view the current address of the module: the LED light on the module will gradually light up, then flash (1) and slow flash (0), record the value, and convert it with a calculator to the current address value.)

说明：  单片机例程！不错啊！适合初学者的秘密武器！！(Single-chip routines! Ah well!)

国外SDI公司的石油钻井通讯协议，包括波特率，帧长，格式等(SDI' s overseas oil drilling communication protocols, including baud rate, frame size, format, etc.)

基于STM32的平衡小车源码(精简入门版)，可实现小车的直立平衡。(Balanced car source code based on STM32 (streamlined entry version) can achieve vertical balance of the car.)
