数字电压表 AD芯片： 采用8位串行A/D转换器ADC0832。 ● 8位分辨率，逐次逼近型，基准电压为 5V ● 5V单电源供电 ● 输入模拟信号电压范围为 0～5V ● 有两个可供选择的模拟输入通道 显示： 使用三个数码管。 显示范围： 0.00 － 5.10 （单位：V） 连接方式： AD_CLK → P1.0 AD_DAT → P1.1 AD_CS → P3.4 模拟输入 → CH0 (AD_DAT = DO + Di) ADC0832输出最大转换值＝FFH (255) 设定最大测量值＝5.1V 255X=5.1 X=0.02 即先乘2再除以100 （小数点放在第三位数码管）

带有期限的作业排序问题：假定只能在一台机器上处理n个作业，每个作业均可在单位时间内完成；又假定每个作业i都有一个截止期限Di>0(它是整数)，当且仅当作业i在它的期限截止以前被完成时，则获得pi>0的效益。求具有最大效益值的可行解。 文件中包含详细的源代码和注释，以实现这个经典的问题。

Embedded computer systems permeate all aspects of our daily lives. Alarm clocks, coffee makers, Digital watches, cell phones, and automobiles are just a few of the devices that make use of embedded systems. The design and development of such systems is unique, because the design constraints are Different for each system. Essential to the development of an embedded system is an understanDing of the hardware and software used for development.

his paper provides a tutorial and survey of methods for parameterizing surfaces with a view to applications in geometric modelling and computer graphics. We gather various concepts from Di® erential geometry which are relevant to surface mapping and use them to understand the strengths and weaknesses of the many methods for parameterizing piecewise linear surfaces and their relationship to one another.

单片机RS232/RS485串行发送实验（双机通讯）。 实验步骤： （1），准备两台598K实验机，确定1号机为发送，2号机为接收； （2），当作RS232接口实验时，1号机和2号机的P3.0和P3.1交叉相连，且两机共地； （3），当作RS485接口实验时，1号机和2号机的A、B作对应连接，同时1,2号机的R/TEN接P1.0, P3.0接R0, P3.1接Di。 （4），先运行2号机，键入[27]-->[EV]使2号机处于接收状态P。，后运行1号机[26]-->[EV]使1号机处于发送状态,P。会闪烁，在1号机键盘上按动数字键，在2号机的数码管上应显示对应的数字键值。

简单的floyd运用 第一行输入一个整数C。C是测试的情况（0< C <=30）.第二行一个正整数N( 0< N <=100),表示道路的总数.紧接N行，每一行包含两个字符串， Si,，Ti，和一个整数Di,代表从Si到Ti的距离(0<= Di <=150)。最后一行有两个字符串，S 和 T，你得找出从S 到 T的最短的距离。地名是不超过120个小写字符的串（从‘a’到‘z’)。假设这里最多有100条直接连通两个地方的路。 Output 输出包含C行，每一行对一种测试情况。对每一种测试情况，输出包含一个整数，假如S 到 T存在一条最短的路,输出从S到T的最短距离,否则输出“-1”.
