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. Use : unpacked click yy, debugging points in the serial simulation can see the result. Demo procedures for the creation of three task A, B, C priority for 2,3,4, A second shows a B every three seconds a show, C every six seconds a show. 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. Note : the system provides display function is complicated, and he is not a direct indication of the serial port, but before the output

本设计主要由数字信号发生器和逻辑分析仪组成,其中数字信号发生器运用了89C51单片机系统,可以重复输出8路循环逻辑移位序列,逻辑分析仪用了89C55单片机系统,可以实现8路信号的采集和显示(时间域和空间域),3级触发字可调,有多种触发功能,可显示时标线,使逻辑分析仪能从大量的数据流中获得有分析意义的数据。-primarily by the design of digital signal generator and logic analyzer, composed of digital signal generator used 89C51 systems, which can output eight repeat cycle shift logic sequence, logic analyzer with the 89C55 microcontroller system, can achieve a 8-way signal acquisition and display (time Victoria and space domain), three adjustable trigger word, a number of trigger functions, can show that the time scale, so the logic analyzer from the large amounts of data flow has been analyzing the meaning of the data.

鉴于MCS-51系统只提供“二级中断嵌套”,提出扩展51系统中断优先级的纯软件方法。其利用51系统内建的中断允许寄存器IE和中断优先级寄存器IP,通过屏蔽字机制来实现;以C51的形式,给出这种扩展方法的函数库实现,为该方法的使用赋予友好、简洁的用户接口。-Given MCS-51 systems only provide "two interrupt nesting," expanded 51 priority system interruption of pure software. The use of 51 built-in system allows interruption Register IE and priority interrupt register IP, through word shielding mechanisms to achieve; C51 in the form of this expansion is the way to achieve functions, methods for the use of empowerment friendly, simple user interface.

模拟交通灯,并带有数字显示的程序。初始时全为红灯,显示“HELLO”字样。然后交通灯以“红绿、红黄、绿红、黄红”四种状态做循环,而且黄灯会闪烁,每种状态都带有到数记时。当按下P3_2时,变成“红红”状态,并显示“STOP”字样! -simulated traffic lights and figures with the procedure. When all of the initial red, shows that the "hello" words. Then traffic lights to the "black, red and yellow, green, red, yellow red" state to do four cycle, but the yellow light flashes, each state will have a few to remember when. When pressed P3_2, into a "red" state, and shows that the "STOP" word!
