STM32双极性步进电机驱动的源代码，完整的功能，库文件。 KEIL下运行-Main function: HAL generic update Fix flag clear procedure: use atomic write operation = instead of ready-modify-write operation |= or &= Fix on Timeout management, Timeout value set to 0 pas

采用C++来封装下STM32的库函数，目前封装了GPIO，UART，TIM Base，SPI等几个外设。-use C++ to encapsulate the STM32 library function, the current package of GPIO, UART, Base, SPI, TIM and several other peripherals
