实现的模拟键盘代码，模拟ps2协议，可以与计算机相连实现键盘的功能，在keil c下开发的。-89s51 achieved through keyboard simulation code, simulation ps2 agreement with the computer keyboard connected to the functions of the c Keil under development(Realize analog keyboard code, analog ps2 agreement, can realize the computer connected to the keyboard functions in keil c developed.-89s51 achieved through keyboard simulation code, simulation ps2 agreement with the computer keyboard connected to the functions of the c Keil under development)

点菜 能实现结账买卖等功能 结账份数能累加 是一个简单的工程(Order to achieve balance sheet transactions and other functions can check out copies of the works is a simple additive)

有五个学生，每个学生有3门课的成绩，从键盘输入以上数据（包括学生号，姓名，三门课成绩），计算出平均成绩，况原有的数据和计算出的平均分数存放在磁盘文件"stud"中。(There are five students, each student has three classes of results, more than from the keyboard input data (including student number, name, class 3 results), calculated the average performance, the status of the original data and calculated the average score placed disk file in the " stud" in.)

单片机汇编程序，来自xll200user，可以供初学者使用(MCU assembler)

微机课程及详细PPT，及各个实验如汇编程序、中断系统等程序，及个实验教材(Computer programs and PPT, and various experiments such as assembler, interrupt system and procedures, and experimental teaching materials)

简单的电子钟程序,用汇编语言编写，用单片机的三个接口(a simple electronic clock which can be used in c8051)

万年历查询及打印系统代码,能查询日历 并输出选定日期的日历，月历，年历(Calendar inquiries and printing system code, can query and output the selected date calendar calendar calendar calendar)

真正的流水灯：（1）第1，3，5，7个灯半亮，其余的全亮。 （2）第1个亮1/8,第2个亮2/8,第3个亮3/8,第4个亮4/8,第5个亮5/8,第6个亮6/8,第7个亮7/8,第8个全亮。 （3）来点小难的，所有的灯逐渐从暗到全亮，再由全亮到暗。 （4）最难的：8个灯从第一个开始依次渐亮，直到最后一个。再从最后一个起渐暗，直到第一个。如此循环往复。这才是真正的流水灯。 (The real light of the water: (1), paragraphs 1, 3, 5, 7 semi-bright lights, the rest of the bright. (2) a bright 1/8, 2 bright 2/8, 3 bright 3/8, 4 bright 4/8, 5 bright 5/8, 6 bright 6/8 7 bright 7/8, 8 full-bright. (3) to a little difficult, all the lights gradually from dark to full brightness, and then from full bright to dark. (4) the hardest: 8 light from the first start in turn gradually brighter, until the last one. From the last one from the dark, until the first. So on ad infinitum. This is true of light water.)

说明：  汇编与c语言的混合编程，很不错的资料，值得一看(Mixed assembly language programming with c, very good information, worth a visit)
