摘要

隨著人們物質(zhì)生活水平的提高，人們對(duì)精神生活的追求也愈加猛烈，對(duì)信息的渴求已成為了人們必不可少的需要，更加簡(jiǎn)捷與別致的信息傳遞方式無疑會(huì)給人們帶來耳目一新的感受。而現(xiàn)代工具務(wù)求簡(jiǎn)捷化、便攜化，因此，搖動(dòng)顯示裝置的到來，必將會(huì)給人們帶來一種新的便利的文化傳遞方式。

“搖動(dòng)顯示裝置〞，俗稱“搖搖棒〞，是基于人的視覺暫留原理的，通過分時(shí)刷新16個(gè)發(fā)光二極管來顯示輸出文字或圖案等信息的顯示裝置。輸出信號(hào)頻率的控制通過單片機(jī)來實(shí)現(xiàn)，用搖動(dòng)傳感器檢測(cè)當(dāng)前搖動(dòng)狀態(tài)。當(dāng)進(jìn)行搖動(dòng)時(shí)，由于人的視覺暫留原理，會(huì)在發(fā)光二極管搖動(dòng)區(qū)域產(chǎn)生一個(gè)視覺平面，在視覺平面內(nèi)的二極管通過不同頻率的刷新，會(huì)在搖動(dòng)區(qū)域內(nèi)產(chǎn)生圖像，從而達(dá)到在該視覺平面上傳達(dá)信息的作用。本文以傳感器和單片機(jī)的實(shí)際應(yīng)用為背景，介紹了以單片機(jī)和傳感器為核心系統(tǒng)搖動(dòng)傳感器和顯示設(shè)計(jì)的基本結(jié)構(gòu)和基本原理。單片機(jī)發(fā)光二極管傳感器

引言

單片機(jī)是隨著大規(guī)模集成電路的出現(xiàn)極其發(fā)展，將計(jì)算機(jī)的CPU，RAM，ROM，定時(shí)/計(jì)數(shù)器和多種I/O接口集成在一片芯片上，形成了芯片級(jí)的計(jì)算機(jī)，因此單片機(jī)早期的含義稱為單片微型計(jì)算機(jī)(singlechipmicrocomputer).它擁有優(yōu)異的性價(jià)比、集成度高、體積小、可靠性高、控制功能強(qiáng)、低電壓、低功耗的顯著優(yōu)點(diǎn).主要應(yīng)用于智能儀器儀表、工業(yè)檢測(cè)控制、機(jī)電一體化等方面,并且取得了顯著的成果.單片機(jī)應(yīng)用系統(tǒng)可以分為:（1）最小應(yīng)用系統(tǒng)是指能維持單片機(jī)運(yùn)行的最簡(jiǎn)單配置的系統(tǒng)。這種系統(tǒng)成本低廉,結(jié)構(gòu)簡(jiǎn)單，常構(gòu)成一些簡(jiǎn)單的控制系統(tǒng)，如開關(guān)狀態(tài)的輸入/輸出控制等。片內(nèi)有ROM/EPROM的單片機(jī)，其最小應(yīng)用系統(tǒng)即為配有晶振，復(fù)位電路，電源的單個(gè)單片機(jī).片內(nèi)無ROM/EPROM的單片機(jī)，其最小應(yīng)用系統(tǒng)除了外部配置晶振，復(fù)位電路，電源外，還應(yīng)外接EPROM或EEPROM作為程序存儲(chǔ)器用.（2）最小功耗應(yīng)用系統(tǒng)是指為了保證正常運(yùn)行，系統(tǒng)的功耗最小.（3）典型應(yīng)用系統(tǒng)是指單片機(jī)要完成工業(yè)測(cè)控功能所必需的硬件結(jié)構(gòu)系統(tǒng)。

本文將使用單片機(jī)對(duì)搖動(dòng)顯示進(jìn)行實(shí)例化，設(shè)計(jì)一個(gè)LED搖動(dòng)顯示器來顯示文字、圖像等信息。把握利用8051型單片機(jī)對(duì)發(fā)光二極管陣列進(jìn)行搖動(dòng)控制的方法。輸出信號(hào)頻率的控制通過單片機(jī)來實(shí)現(xiàn)，用搖動(dòng)傳感器檢測(cè)當(dāng)前搖動(dòng)狀態(tài)，用16個(gè)發(fā)光二極管進(jìn)行不同頻率的亮滅刷新，通過手動(dòng)搖動(dòng)可顯示輸出文字及圖案等信息。當(dāng)進(jìn)行搖動(dòng)時(shí)，由于人的視覺暫留原理，會(huì)在發(fā)光二極管搖動(dòng)區(qū)域產(chǎn)生一個(gè)視覺平面，在視覺平面內(nèi)的二極管通過不同頻率的刷新，會(huì)在搖動(dòng)區(qū)域內(nèi)產(chǎn)生圖像，從而達(dá)到在該視覺平面上傳達(dá)信息的作用。LED顯示棒，又稱搖搖棒，是一種利用視覺暫留效應(yīng)制作的“高科技〞玩具?？梢杂谩办o如處子，動(dòng)如脫兔〞來形容它，即當(dāng)靜止時(shí)，它只是幾個(gè)LED發(fā)光二極管（后簡(jiǎn)稱LED），而一旦依照一定的頻率去晃動(dòng)它，它就會(huì)隨著位置的變化而變化（亮或滅），最終顯示一幅圖片或字符串。
