數(shù)字電壓表 AD芯片： 采用8位串行A/D轉(zhuǎn)換器ADC0832。 ● 8位分辨率，逐次逼近型，基準(zhǔn)電壓為 5V ● 5V單電源供電 ● 輸入模擬信號(hào)電壓范圍為 0～5V ● 有兩個(gè)可供選擇的模擬輸入通道 顯示： 使用三個(gè)數(shù)碼管。 顯示范圍： 0.00 － 5.10 （單位：V） 連接方式： AD_CLK → P1.0 AD_DAT → P1.1 AD_CS → P3.4 模擬輸入 → CH0 (AD_DAT = DO + Di) ADC0832輸出最大轉(zhuǎn)換值＝FFH (255) 設(shè)定最大測(cè)量值＝5.1V 255X=5.1 X=0.02 即先乘2再除以100 （小數(shù)點(diǎn)放在第三位數(shù)碼管）

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.

簡(jiǎn)單的floyd運(yùn)用 第一行輸入一個(gè)整數(shù)C。C是測(cè)試的情況（0< C <=30）.第二行一個(gè)正整數(shù)N( 0< N <=100),表示道路的總數(shù).緊接N行，每一行包含兩個(gè)字符串， Si,，Ti，和一個(gè)整數(shù)Di,代表從Si到Ti的距離(0<= Di <=150)。最后一行有兩個(gè)字符串，S 和 T，你得找出從S 到 T的最短的距離。地名是不超過(guò)120個(gè)小寫字符的串（從‘a(chǎn)’到‘z’)。假設(shè)這里最多有100條直接連通兩個(gè)地方的路。 Output 輸出包含C行，每一行對(duì)一種測(cè)試情況。對(duì)每一種測(cè)試情況，輸出包含一個(gè)整數(shù)，假如S 到 T存在一條最短的路,輸出從S到T的最短距離,否則輸出“-1”.
