电路图和程序是正确的。如果问题可以去我的博客吨..

与终端的通讯 1.1 采用标准的UART通讯协议，波特率为9600，没有校验位，一个停止位。 1.2 通讯的过程是主从式半双工的。 1.3 详细的通讯协议参见芮鹤龄的文档。 -2051

此包包括以HD4478位控制器的LCD说明，另外有一89c51为例，采用直连方式编写的lcd驱动程序，效果为将要显示字符以左滚动方式双行显示，难度不大，但体现部分原理，水平不高，共同进步！-HD4478 to the LCD controller note, another example of a 89c51, with Direct Connect approach to the preparation of the LCD driver and the results will be revealed for the characters to the left of double rolling basis, not more difficult, but embodies some principles, the level is not high, and common progress!

MCS51外部中断1和定时器T0的应用，外部中断1连接一个按键，通过调节按键改变定时器的值，定时器输出连接一个蜂鸣器-MCS51 and one external interrupt timer T0 applications, external interrupt 1 to connect a button, through the adjustment button to change the timer value, the timer output to connect a buzzer

pic单片机c口的控制 单片机相应的I/O口设置为输出口，输出高电平时LED点亮，反之，LED不亮。利用软件延时的办法实现05S延时，实现LED流水灯的效果。-pic Singlechip c I control the corresponding single-chip I/O port set to output, the output high when the LED light, on the contrary, LED does not shine. Approach to the use of software latency delay 05S realize, realize LED lights flowing effect.
