以MPS430F149为硬件平台，利用I/O口模拟I2C总线协议，对日精的时钟芯片S35390A_C做了初始化子程序、读时钟子程序、写时间子程序、脉冲为1赫兹输出子程序。-To MPS430F149 for the hardware platform, the use of I/O port simulation I2C bus protocol on-chip clock nissei S35390A_C done initialization subroutine, read subroutine clock, the time to write subroutines, pulse for 1 Hz output subroutine.

算24点”作为一种扑克牌智力游戏，游戏内容为从一副牌中抽去大小王2张，任意抽取4张牌（称牌组），用加、减、乘、除（可加括号）把牌面上的数算成24，每张牌必须用一次且只能用一次。我们可以人工计算，当然也可以用计算机来处理。本程序主要是借助计算机利用设计好的算法来计算24点问题。 该24点游戏程序内容主要包括界面显示，自动运算24点以及手动计算24点三部分，采用模块化开发方法，并汇编语言编写程序代码。-Count 24 points " as a mental poker game, a game content license from the King of removing the size 2, 4 samples of arbitrary license (a license that group), with add, subtract, multiply, divide (which can be bracketed ) to the surface of the card count as 24, each card must be used once and only once. We can manually, of course, can also be used to deal with the computer. This procedure is the use of the use of computer algorithms designed to calculate the 24 points. The 24-point games, including the contents of the main screen, automatic operation and manual calculation of 24 points, 24 points, three-part, modular development methodology, and assembly language programming code.
