- 51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,虽然也可以用几个三极管进行模拟转换,但是还是用专用芯片更简单可靠。我们采用了三线制连接串口,也就是说和电脑的9针串口只连接其中的3根线:第5脚的GND、第2脚的RXD、第3脚的TXD。这是最简单的连接方法,但是对我们来说已经足够使用了,电路如下图所示,

- 所谓“串行通信”是指外设和计算机间使用一根数据信号线(另外需要地线,可能还需要控制线),数据在一根数据信号线上一位一位地进行传输,每一位数据都占据一个固定的时间长度。这种通信方式使用的数据线少,在远距离通信中可以节约通信成本。在简单的应用中, 只需要有3条线即可完成通信, 分别是 第二脚RXD , 第3脚TXD ,第5脚GND。串行通信与单片机之间的接口:由于串行通信的电平逻辑定义是+15V( 高电平1)-15V(低电平0) 而单片机中分别用5V ,0V 来表示1,0 它们之间必须通过电平转换才
