说明：  非常详细的基于stm32的ATT7022驱动程序！除了读取各个计量参数外还包含电压、电流、功率以及相位角的校正和温度系数补偿。该程序是本人参考官方手册所写且经过实际测试已用于项目中，里面每个函数都有详细的注释，对新手具有很大的参考价值(Very detailed STM32 based ATT7022 driver! In addition to reading each measurement parameter, it also includes voltage, current, power and phase angle correction and temperature coefficient compensation. This program is written by myself with reference to the official manual and has been used in the project after actual test. Each function in it has detailed comments, which is of great reference value to novices)

说明：  应用于粗糙表面线接触弹流润滑计算，自动生成随机分布的表面粗糙度程序。(It is applied to the calculation of linear contact elastohydrodynamic lubrication on rough surface to automatically generate randomly distributed surface roughness program.)

ANCF的有限元说明文件，里面有ANCF附有代码程序及ANCF的实现方法。(ANCF finite element description document, which contains ANCF with code procedures and ANCF implementation methods.)

相电流重构的详细分析说明，可以帮助初学者，理解电机控制中的这个关键点(phase current reconstruct)
