说明：  在串口通信中，通过编写单片机程序知道，我们应对如下参数进行设置：波特率、数据位和停止位、奇偶校验位。如果自己编写上位机的时候，我们考虑的不能仅仅是这些了，下面介绍上位机开发过程中需要特别注意的知识点。 上位机快速开发教程
(In the serial communication, through the MCU is programmed to know, we should the following parameters settings: baud rate, data bits, and stop bits, parity bit. If you write the host computer, we should consider not just these, the following describes the process of development of the host computer need to pay special attention to the knowledge points.)
