基于STM32平台GRBL V1.1F源代码IAR工程文件，效果非常棒，比AVR328和2560效果好多了，用机器实际测试过，可以直接使用。
单片机源程序如下:

- 之前在github上看到了grbl-0.9j在stm32上的移植，于是照猫画老虎，移植了grbl1.1f-20170131，
- 增加了USB虚拟串口，不再需要外接转换芯片，但其他功能都没有调试，存在严重问题。此次移植了
- grbl1.1f-20170801，同时进行了少许调试，目前通讯正常，步进电机接口、冷却和主轴正常，同时
- 加入了四相五线步进接口（x和y），这些在cpu_map.h中有相应定义。但手头没有机器，尚未实机测
- 试，慎用！
