uart
- 采用软件方法来实现单片机的通用串口引脚来模拟UART。根据要求采用P1.0作为发送端(TXD),P1.1做为数据接受端(RXD),并采用全双工通信模式。由于MAX232电平转换芯片除了做UART的几个引脚后,还剩余T2IN,T2OUT,R2IN,R2OUT.所以采用模仿UART的接法.每次通信,发送的数据加1,接收的数据加2.用51系列单片机。-The use of software methods to achieve single-chip Universal Serial pin to s

- 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,
