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)

STM32汇编LCD初始化
应用背景
本人原创STM32汇编实现LCD的显示,目前搜遍全球也没有STM32汇编实现LCD显示的代码。 编译器 ARM-NONE-EABI ,是在LINUX下编译的。
代码很复杂不容易看懂,我用了很长时间才写出来,大概有1000行汇编代码,写了半个多月才写出来,真是不容易啊。 程序包括IO设置 时钟初始化,NVIC中断设置,定时器,温度传感器等,红外遥控, 然后在LCD上显示
关键技术
初始化代码

本教程主要讲述计算机指令运行机制及汇编语言的相关知识,并用详实的例子来讲解如何使用O汇编语言来编写程序。汇编语言是计算机低级语言,它直接对应的是计算机机器指令,据有执行高效的特点,但由于它的底层性,指令浩繁复杂,如果你熟悉如MASM、FASM或者NASM等其它的汇编语言,那么你将能够很容易地学会使用O语言,它的内部机制与其它汇编语言是一致的;如果你没有接触过汇编语言,那么本教程将为你打开计算机语言的大门,深入细致地解剖聪明的计算机大脑的思考轨迹。如果你使用过C或者其它的计算机语言将对学习O语言有一定的帮助。-the handbook focuses on the operation of computer instructions and mechanisms related to the compilation of language knowledge, and the use of detailed examples to explain how to use the O Series language programming. Language is a compilation of computer low level language, which directly correspond to the computer machinery orders, according to the efficient implementation of the characteristics But since they are bottom, voluminous complex instructions, if you are familiar with such as Shape, FASM or Assemble the compilation and other languages, then you will be able to easily learn how to use O language, The internal mechanism and the other assembly language is unanimous; If you had any contact with assembly language. Then you ha
