串口调试程序

1. 发送过程：在发送时必须保证TI=1:即发送缓冲器为空，否则将导致数据发不出去，如果想强制发送可以用：TI=1.具体发送数据：利用printf(“akjdfaklfj”) 函数直接发送即可。



2. 接收过程：在接收时多选用中断方式，这样可以节约CPU的时间，提高效率，

-1 serial port debugger. Send process: to be sent to ensure that TI = 1: that is, send buffer is empty, otherwise they would be unable to lead to the data, if you want to send can be mandatory: TI = 1. Specific send data: Using printf (　akjdfaklfj ) function can be sent directly. 2. Receiving process: when in the receiving mode selection interruption, thus saving CPU time, improve efficiency,
