显示模块的程序，有数码管显示功能和按键功能，灯的功能，能方便的大家学习数码管。当数码管特定的段加上电压后，这些特定的段就会发亮，以形成我们眼睛看到的字样了。如：显示一个“2”字，那么应当是a亮b亮g亮e亮d亮f不亮c不亮dp不亮。LED数码管有一般亮和超亮等不同之分，也有0.5寸、1寸等不同的尺寸。小尺寸数码管的显示笔画常用一个发光二极管组成，而大尺寸的数码管由二个或多个发光二极管组成，一般情况下，单个发光二极管的管压降为1.8V左右，电流不超过30mA。发光二极管的阳极连接到一起连接到电源正极的称为共阳数码管，发光二极管的阴极连接到一起连接到电源负极的称为共阴数码管。常用LED数码管显示的数字和字符是0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F。

这个例子如果运行,将在仿真的PC窗口中的第1,2,3行显示一些信息后,在随机位置显示 1 ~ 5 .由于keil c51默认不支持重入函数,它的重入函数使用仿真的重入栈而不使用系统栈,而Small RTOS 51没有进行重入栈管理,所以在TaskA~TaskE虽然及其相似,但不能合并. (2)编译时会有5个警告,其中一个是因为没有使用一个系统函数OSSendSignal引起,它可以忽略.另4个是禁止任务间变量覆盖分析引起,必须忽略.感谢网友John X. Liu,在这个例子中我使用了他编写的仿真(dllPc51Emu.dll),这个dll原来是为他移植的Ucos-ii for keil c51的例子编写.-If you are running this example, will the PC emulation window, the first 1,2,3-line display some information, at random locations show " 1 " ~ " 5" . Keil c51 as the default does not support the re-entry function, which re- into the function of the weight stack instead of using the simulation using the system stack, while the Small RTOS 51 not been re-stack management, and so TaskA ~ TaskE though its similar, but not combined. (2) compile-time there will be five warnings, One of them is because there is no cause to use a system function OSSendSignal, it can be ignored. The other four are prohibited between the variables covered analyze the task to be ignored. thank User
