基于freescalehcs12系列單片機(jī)設(shè)計(jì)和實(shí)現(xiàn)搶答器外文翻譯(存儲(chǔ)版)
【正文】 difficulty of the question and so on. These issues will remain to be addressed in future development.4外文資料譯文基于Freescale HCS12系列單片機(jī)設(shè)計(jì)和實(shí)現(xiàn)搶答器搶答器也被稱(chēng)為第一信號(hào)鑒別器，它被廣泛應(yīng)用于各種比賽。此外，如果有人得到機(jī)會(huì)來(lái)回答這個(gè)問(wèn)題，但在允許的時(shí)間之前沒(méi)有給出正確的結(jié)果，他或她不會(huì)得到分?jǐn)?shù)，加班的信號(hào)也會(huì)被發(fā)送，主機(jī)將宣布正確答案。與此同時(shí)，定時(shí)電路開(kāi)始工作，如果沒(méi)有人得到機(jī)會(huì)允許的時(shí)間內(nèi)回答問(wèn)題，微控制器會(huì)發(fā)出單詞“超市”到PC電腦，如果有人按下指定時(shí)間內(nèi)競(jìng)爭(zhēng)的關(guān)鍵，單片機(jī)將送他或她的編號(hào)。該開(kāi)發(fā)板采用MC9S12DG128為核心，采用模塊化設(shè)計(jì)方法，它提取的I / O資源的一部分，而且還提供了每個(gè)模塊有相應(yīng)的接口電路。在完成初始化后，系統(tǒng)已經(jīng)等待了比賽開(kāi)始的信號(hào)與圓形模式，直到信號(hào)到來(lái)。然而，由于開(kāi)發(fā)板的硬件限制，有些功能未能實(shí)現(xiàn)，如開(kāi)發(fā)板沒(méi)有足夠的LED數(shù)碼管同時(shí)顯示所有選手的分?jǐn)?shù)，主機(jī)可以根據(jù)問(wèn)題的難度不會(huì)調(diào)整答題時(shí)間等。主程序的主體是一個(gè)環(huán)結(jié)構(gòu)。搶答器的硬件首先設(shè)計(jì)。設(shè)計(jì)也是必要的。搶答器應(yīng)具有較強(qiáng)的分辨能力的選手在動(dòng)作來(lái)回答，其分辨率達(dá)到至少幾毫秒后響應(yīng)方的要求和功能進(jìn)行了分析，下面的電路是必需的，一般：搶答器電路該電路有兩個(gè)功能：一個(gè)是確定誰(shuí)按下按鈕，播放器的數(shù)量，并保存號(hào)碼，另一種是從扣扣禁止的其他選手或作出其他按鈕不可用2時(shí)序電路主機(jī)可以設(shè)置比賽時(shí)間和時(shí)間預(yù)先設(shè)定電路答題時(shí)間。在本文中，飛思卡爾的HCS12 [ 13 ]被設(shè)計(jì)成一個(gè)核心組成部分，實(shí)現(xiàn)了智能數(shù)字搶答器與8通道[ 48 ] ，但對(duì)技術(shù)，功能等方面有所突破，與過(guò)去相比響應(yīng)。s input channel is turned off. To be noted that, if the petition flag is 1, it should be cleared Responder is one of the essential devices in various knowledge and intellectual contests, the development of better and more intelligent digital responder is very significant. Responder designed in this paper can achieve a responder39。s number。t get the score, the overtime signal will be also send, the host will declare the right answer. Freescale HCS12 contains timer module, the timer module can be directly used.Overtime circuit HCS12 will send overtime signal when time goes beyond the set time, this signal will be transferred to the PC puter by the serial port. The next question will be proceeded to answer.Scores count and display circuit. When host presses the answer key, it is time to start to answer, if one player presses the answer key, his or her number will be recorded, his or her score will be counted and displayed on the LED digital tubes. Bedside the circuits designed above, some necessary logicdesigns are also necessary. The logic designs are as following:First, the host will read the question which will show in the LCD。它可以判斷一個(gè)選手的數(shù)量準(zhǔn)確，公正，直觀。飛思
