在单片机与PC机通讯的时候,存在一个单片机有一个全双工的串行通讯口,所以单片机和电脑之间可以方便地进行串口通讯。进行串行通讯时要满足一定的条件,比如电脑的串口是RS232电平的,而单片机的串口是TTL电平的,两者之间必须有一个电平转换电路,我们采用了专用芯片MAX232进行转换,这个是专门为电平转换芯片,其集成度高,外接电路简单,使用十分方便。

In Chanpianji communication with PC machines, the existence of a serial communications Quanshuanggong Chanpianji a mouth, so Chanpianji between computers and can be conveniently carried out Chuankou communications. For serial communication to meet certain conditions, such as computer Chuankou is RS232 call ping, and the Chuankou Chanpianji is TTL(电平), between the need for a call ping conversion circuit, we used a dedicated chip MAX232 conversion, this is specifically for the conversion of chip-ping, the master degrees high, external hard disks circuit simple. very convenient to use.
