说明：  STM32_SX1278实现LORA通信STM32F103完美实现(STM32_SX1278 achieves perfect implementation of LORA communication STM32F103)

该程序是本人用AVR ATtiny13写的的一个只用4个IO口驱动两相四线制步进电机的程序，还可以控制转动的上下限（祥见程序屏蔽部分）对使用两相四线步进电机的初学者来说无疑是一笔珍贵的学习资源，对要求以最低成本驱动两相四线步进电机的使用者来说，更是提供了一个有利的参考。推荐！(I use the program is written in AVR ATtiny13 a four IO only I drive two-phase four-wire stepper motor program, but also can control the rotation of the upper and lower limits (祥见shielding part of the procedure) on the use of two-phase four-step beginners into the motor is undoubtedly a valuable learning resource for the lowest cost drive requires two-phase four-wire stepper motor users are provided a favorable reference. Recommended!)
