grbl1.1f for stm32
依照github上的样例移植了grbl1.1，原项目为"https://github.com/MaxwellXyao/GRBL-0.9j-for-STM32".我所做的改动有： 1.版本号提示为1.1f. 2.修改了端口定义，需要注意! 3.将串口通讯改为usb虚拟串口，充分利用stm32f103的特性. 4.修复一些bug
有许多功能未验证，如限位等

On github there are some people doing the similar work.This project is based on "https://github.com/MaxwellXyao/GRBL-0.9j-for-STM32". Compared to their work,I changed some features: 1.GRBL version to 1.1f20170801. 2.CPU map changed,warning! 3.Changed UART to USB virtual COM port to make full use of stm32f10x. 4.Fix some bugs.
However there are some functions I did't transplant or test,such as limit,STEP_PULSE_DELAY and so on.
