用气泡法对数字进行排序。这个程序介绍了一种基于气泡法的数字排序方法。首先比较前两个数字，如果第一个数字更多，他就和第二个数字换位，以此类推。一旦正确的号码到位。重复此过程，直到完成排序。

实现STM8L152串口3数据的收发，亲测可以正常使用(STM8L152 serial port to achieve 3 data transceiver, pro test can be used normally.)

交通灯的设计开发，实现道路交通的智能控制，可以根据道路实际情况改变通行时间(The design and development of traffic lights can realize the intelligent control of road traffic, and change the passage time according to the actual situation of the road)

说明：  转 VF算法控制三相无刷电机，开环控制，无传感器(VF controlled three-phase brushless motor) 包含FOC 核心算 clark park ipark svpwm IQ格式的计算，值得参考。只要设定电压与频率比就能让电机，属于开环控制，很好验证硬件与软件的程序。(VF controlled three-phase brushless motor is controlled by VF algorithm and open-loop control. The calculation of Clark Park Ipark SVPWM IQ format is included in VF controlled three-phase brush motor. As long as the voltage to frequency ratio is set, the motor belongs to open-loop control, which can verify the hardware and software program well.)

说明：  三相对称短路计算用于生成节点导纳矩阵以及节点阻抗矩阵，进行短路电流、节点电压的计算(Three phase short circuit calculation used to generate the nodal admittance matrix and the node impedance matrix, the short circuit current, node voltage calculation)
