串口，这个程序很好啊啊 ，欢迎下载撒

通过8255查询键值，显示不同的数字。k1显示1，K2显示2，K1和K2显示3,如此类推。最多能显示7。-8,255 inquiries through the keys, show different figures. K1 shows a, K2 showed 2, K1 and K2 showed three, and so forth. The most that can be shown 7.

这个两个rar文件是关于定时器0使用的例子, 也是我第一次使用定时器0做的实验程序: 1. T0_ASM.rar, (带中文注释的C51语言例程), 利用定时器0中断实现LED灯的简单控制。 2. T0_C51.rar, (带中文注释的51汇编语言例程), 利用定时器0中断实现LED灯的简单控制。 两个同样功能的timer0中断程序都在MCU51-63K仿真器下通过实验, 小虾们可以试试看。 -Rar files that are both about the example of the use of Timer 0 is also the first to use my timer 0 of the experimental procedure to do: 1. T0_ASM.rar, (with English language routines C51 annotated), make use of the timer 0 interrupt implementation easy control of LED lights. 2. T0_C51.rar, (with English Notes 51 assembly language routines), use of the timer 0 interrupt achieve easy control of LED lights. Same function in both programs at timer0 interrupted MCU51-63K emulator through the experiment, shrimp can give it a try.
