流行的实时时钟芯片操作源代码，包括各个基本操作-Popular real-time clock chip to operate the source code, including all the basic operation

电子钟的单片机实现,这里配合时钟芯片令时间更加准确,LCD界面更加人性化-Realize the single-chip electronic bell, where the time clock chip with a more accurate, LCD interface more user-friendly

设计要求： 出于不同目的的旅客对交通工具有不同的要求.例如,因公出差的旅客希望在旅途中的时间尽可能短,出门旅游的游客则期望旅费尽可能省,而老年旅客则要求中转次数最少.编制一个全国城市间的交通咨询程序,为旅客提供两种或三种最优决策的交通咨询. //请保留此信息，谢谢 1.需求分析: (1)提供对城市信息进行编辑(如添加或删除)的功能. (2)城市之间有两种交通工具:火车和飞机.提供对列车时刻表和飞机航班进行编辑(增设或删除)的功能. (3)提供两种最优决策:最快到达或最省钱到达.全程只考虑一种交通工具. -design requirements : For different purposes to transport passengers have different requirements. For example, on official business travelers in the journey time as short as possible away tourists expect possible travel provinces, and elderly passengers asked the least number of transit. establishment of a national inter-city traffic advisory proceedings, for the visitors two or three best decision of the Transport Advisory.// Please keep this information, I would like to thank one. demand analysis : (1) to provide information on the city for editing (such as add or delete) function. (2) Town between the two modes : Train and aircraft. Schedules for the train and flights for editing (created or deleted) function. (3)

汇编语言写的菜单程序，类似于DOS下的EDIT功能，编辑功能未实现。-Menu Programs written in assembly language, similar to DOS under the EDIT function, edit function is not implemented.

从键盘读入一个四位的十六进制数，CRT显示等值的二进制数. 由于每个十六进制数位对应4个二进制，所以每读入一个十六进制位后，即可将其对应的4个二进制位依次输出。由于数字‘０’~ ‘９’的ASCⅡ码为30H～39H,字母‘a’～‘f’与 ‘A’～‘F’的ASCⅡ码为61H～66H 与41H～46H ，因此，如果输入的字母为数字‘０’～‘９’，则其低４位即为对应的二进制位；如果输入的字符为字母‘ａ’～‘ｆ’或‘Ａ’～‘Ｆ’，则需要减７，然后通过移位将低４位依次输出。 -Reading from the keyboard into a 4 hexadecimal number, CRT display equivalent binary number. Since each hexadecimal number of the corresponding 4-bit binary, so every time into a hexadecimal places, can be its corresponding 4-bit binary sequence output. Due to the number

对图像做了简单处理，最后一段代码段实现4各功能，汇编运算较多-Do a simple image processing, the realization of the last paragraph of the code segment 4 of the function, the compilation of more computing

这个程序我花了好久才写出来的,非常的好,它可以产生很高性能的三角波,一般程序不易产生如此好的波形.-this process I have spent a long time before the writing, very good, and it can produce a very high-performance triangular wave, the general procedures have not been so good waveform.

汇编语言编写的类似俄罗斯方块的游戏程序-compiled languages like Tetris game procedures

硬件可以捕获三轴的值，然后进行rfid计算
