Description: 平凡的单片机,MCS-51单片机教程 1、何谓单片机 一台能够工作的计算机要有这样几个部份构成:CPU(进行运算、控制)、RAM(数据存储)、ROM(程序存储)、输入/输出设备(例如:串行口、并行输出口等)。在个人计算机上这些部份被分成若干块芯片,安装一个称之为主板的印刷线路板上。而在单片机中,这些部份,全部被做到一块集成电路芯片中了,所以就称为单片(单芯片)机,而且有一些单片机中除了上述部份外,还集成了其它部份如A/D,D/A等。

[SCMucos51在KeilC51上仿真运行

Description: Demo程序经Keil701编译后,代码量为7-8K,可直接在KeilC51上仿真运行。 使用方法:解压后双击yy项目,点调试即可在串口仿真看到结果。 Demo程序创建了3个任务A、B、C优先级分别为2、3、4,A每秒显示一次,B每3秒显示一次,C每6秒显示一次。从显示结果看,显示3个A后显示1个B,显示6个A和2个B后显示1个C,结果显然正确。用户可以仿照范例运用更多系统API函数写出自己的程序。只要程序中有显示语句就可以用软件仿真器看结果。注意:系统提供的显示函数是并发的,他不是直接显示到串口,而是先输出到显存,用户不必担心IO慢速操作影响程序运行。串口输入也采用了同样的技术,他使得用户在CPU忙于处理其他任务时照样可以盲打输入命令。 将EXL2-shell目录下的文件覆盖yy目录下的同名文件,将word.c、yyshell.c、yyshellsub.c、mystring.c加入项目,删除yy1.c,编译后调试即可。输入help可得到在线帮助,具体命令用法见文章说明。 yangye网友推荐http://www.sics.se/~adam/lwip/网站学习TCPIP,该网站开放源代码的lwip是专为8bit和16bitMCU设计的TCPIP协议栈,已在多种CPU上移植成功,推荐大家下载。-Demo processes Keil701 compiler, code capacity of 7-8K to be directly in KeilC51 on simulation run.

Looking at the results from the show, a show three shows a B, showed six A and two B shows a C, the result is obviously correct. Users can use more modeled on the example of system API function to write their own procedures. As long as the procedures are shown on the statement can be used simulation software for the outcome.

Description: 1,消除按键的抖动问题 因为按键在闭合或断开过程中出现一段抖动期,主要由于按键的不稳定性引起的,这时会呈现一串页脉冲,时间的长短和开关的机械特性有关。一般在5ms~10ms之间。为保证CPU对键的一次闭合作一次处理,必须去抖动。在键的稳定闭合或断开时读键的状态。 2,据EICE51原理图编写并调试一个键输入子程序,其功能为判断键盘上有无键输入,若有键入,作去抖动处理后,计算输入键的键号送累加器A。-eliminate jitter button issues as keys or disconnect the closure process for some jitter period, mainly due to the instability of the keys to the cause, then it will result in a bunch of pages pulse, the duration and switches on the mechanical properties.
