The RTT function practice of J-link

Sometimes use the serial port as the debug output, but sometimes the serial port of the hardware is not so much, inadvertently found can use J-link RTT function, with it no longer need to worry about the lack of debugging window. Specifically how to make reference to a Netizen's post: http://www.amobbs.com/thread-5595476-1-1.html. According to this post, I have a demo routine based on Stm32f103ze, which uses mdk4.7a,j-link4.98b, and the routines see Http://pan.baidu.com/s/1dDQA7gX.
