AVR系列單片機(jī)C語(yǔ)言編程與應(yīng)用實(shí)例

本書(shū)針對(duì)Atmel公司的AVR系列單片機(jī)和ImageCraft公司的ICC AVR開(kāi)發(fā)環(huán)境，詳細(xì)地介紹了AT90LS8535的C語(yǔ)言程序設(shè)計(jì)。全書(shū)共有13章，其內(nèi)容既涉及到了單片機(jī)的結(jié)構(gòu)原理、指令系統(tǒng)、內(nèi)容資源和外部功能擴(kuò)展，又包含了單片機(jī)的編程工具——ICC AVR C編程器的數(shù)據(jù)類型、控制流、函數(shù)和指針等。本書(shū)的特點(diǎn)是：深入淺出，從最基本的概念開(kāi)始，循序漸進(jìn)地講解單片機(jī)的應(yīng)用開(kāi)發(fā)；列舉了大量實(shí)例，使讀者能從實(shí)際應(yīng)用中掌握單片機(jī)的開(kāi)發(fā)與應(yīng)用技術(shù)。本書(shū)適合作為從事單片機(jī)開(kāi)發(fā)人員的參考用書(shū)。書(shū)中先后講解了C語(yǔ)言基礎(chǔ)、AVR單片機(jī)基礎(chǔ)，并舉了一些簡(jiǎn)單的實(shí)例。本書(shū)非常適合初學(xué)者。【目錄信息】第1章單片機(jī)系統(tǒng)概述

也可完成圖形顯示.低電壓低功耗是其又一顯著特點(diǎn)。由該模塊構(gòu)成的液晶顯示方案與同類型的圖形點(diǎn)陣液晶顯示模塊相比，不論硬件電路結(jié)構(gòu)或顯示程序都要簡(jiǎn)潔得多，且該模塊的價(jià)格也略低于相同點(diǎn)陣的圖形液晶模塊。基本特性: 低電源電壓（VDD:+3.0--+5.5V）顯示分辨率:128×64點(diǎn) 內(nèi)置漢字字庫(kù)，提供8192個(gè)16×16點(diǎn)陣漢字(簡(jiǎn)繁體可選) 內(nèi)置 128個(gè)16×8點(diǎn)陣字符 2MHZ時(shí)鐘頻率顯示方式：STN、半透、正顯驅(qū)動(dòng)方式：1/32DUTY，1/5BIAS 視角方向：6點(diǎn) 背光方式：側(cè)部高亮白色LED，功耗僅為普通LED的1/5—1/10 通訊方式：串行、并口可選內(nèi)置DC-DC轉(zhuǎn)換電路，無(wú)需外加負(fù)壓無(wú)需片選信號(hào)，簡(jiǎn)化軟件設(shè)計(jì) 工作溫度: 0℃ - +55℃ ,存儲(chǔ)溫度: -20℃ - +60℃ 12864（帶字庫(kù)漢字顯示演示程序）

PIC16F877 單片機(jī)的鍵盤(pán)和LED 數(shù)碼顯示接口

PIC16F877 單片機(jī)的鍵盤(pán)和LED 數(shù)碼顯示接口 1 PIC16F877單片機(jī)與鍵盤(pán)和LED數(shù)碼顯示的硬件接口電路單片機(jī)的許多應(yīng)用都需要進(jìn)行人機(jī)對(duì)話，最簡(jiǎn)單的人機(jī)對(duì)話需要LED 數(shù)碼管顯示數(shù)字和少量字符；鍵盤(pán)是解決計(jì)算機(jī)輸入的簡(jiǎn)單手段；借此可以向計(jì)算機(jī)輸入程序、置數(shù)、送操作命令、控制程序的執(zhí)行等等，所以使用非常廣泛。圖1 鍵盤(pán)、LED數(shù)碼顯示與PIC16F877 單片機(jī)的接口電路本例中采用8 個(gè)按鍵組成的小鍵盤(pán)，4 只共陰極的LED 數(shù)碼管，采用4 片74LS373 驅(qū)動(dòng)數(shù)碼管，采用的驅(qū)動(dòng)方法是靜態(tài)方式。使用1 片74LS245 作為鍵盤(pán)的接口；這些外圍器件與PIC16F877 單片機(jī)的接口電路如圖1 所示，這種連接方法與51 系列的單片機(jī)連接方法一樣，其他的連接方法還有好幾種，PIC16F877 單片機(jī)的鍵盤(pán)輸入接法還有其他特殊而十分方便好用的方式。8 鍵鍵盤(pán)通過(guò)74LS245 與單片機(jī)相連，鍵盤(pán)按鍵狀態(tài)的數(shù)據(jù)輸入由RC3 輸出腳控制；當(dāng)RC3=“0”時(shí)，鍵盤(pán)狀態(tài)從74LS245 的A 端輸出到單片機(jī)的PORTB口，此時(shí)讀PORTB口的數(shù)據(jù)即為鍵盤(pán)狀態(tài)。為了及時(shí)地響應(yīng)鍵盤(pán)操作，需要經(jīng)常對(duì)鍵盤(pán)進(jìn)行掃描；掃描的方式有許多種，我們將鍵盤(pán)的掃描程序安排在主程序的循環(huán)執(zhí)行過(guò)程中的方式，并采用20ms延遲來(lái)消除按鍵的抖動(dòng)問(wèn)題，此外，為了實(shí)現(xiàn)每按鍵一次只響應(yīng)一次的功能，在執(zhí)行相應(yīng)的按鍵程序之前，必須確保按鍵已經(jīng)松開(kāi)；在本例中這一措施有效的防止了數(shù)據(jù)抖動(dòng)過(guò)快的問(wèn)題。LED 數(shù)碼顯示有動(dòng)態(tài)掃描和靜態(tài)顯示兩種方式（圖1 采取的方式為靜態(tài)方式），在動(dòng)態(tài)掃描方式中，各數(shù)碼顯示是輪流點(diǎn)亮的，即控制數(shù)碼顯示的位選信號(hào)和相應(yīng)的要顯示的數(shù)碼的字形代碼同時(shí)逐一送出，反復(fù)不已，由于視覺(jué)的暫留現(xiàn)象，卻好象全都點(diǎn)亮著，這種電路的接法以后再介紹。在靜態(tài)方式中，只要將數(shù)據(jù)送出鎖存以后，各數(shù)碼顯示的數(shù)據(jù)不需要刷新，只要數(shù)據(jù)不需改變，就可以不去管他，所以稱為靜態(tài)顯示。在圖1 電路中，輸出顯示的操作簡(jiǎn)化為對(duì)74LS373 的并口操作而已。由于靜態(tài)方式的工作原理比較簡(jiǎn)單，編程也比較直觀簡(jiǎn)單，程序間的相互關(guān)聯(lián)很少。因此編程容易，但要增加硬件，成本較高；與之相比，動(dòng)態(tài)掃描的編程雖然要復(fù)雜一些，但因其所用硬件少，成本低。由數(shù)碼轉(zhuǎn)化為字形代碼可采用軟件譯碼、硬件譯碼等兩種方式。軟件譯碼是將各數(shù)碼的字形代碼構(gòu)成一個(gè)表格存儲(chǔ)于內(nèi)存之中，在顯示數(shù)碼時(shí)，通過(guò)執(zhí)行查表程序而得到相應(yīng)的字形代碼，再將之送入數(shù)碼顯示輸出電路進(jìn)行顯示，本例即采用這種方式，這種方式的編程與單片機(jī)有關(guān)，在程序中給出了PIC16F877 的編程例程，對(duì)需要熟悉PIC16F877 單片機(jī)的人員有一定的參考價(jià)值。硬件譯碼則采用CD4511、74LS46、74LS47、74LS48、74LS49等BCD 碼—7段鎖存、譯碼、驅(qū)動(dòng)芯片直接譯出字形代碼，點(diǎn)亮LED。74LS373 由LE 端對(duì)要顯示的數(shù)據(jù)進(jìn)行鎖存控制，實(shí)現(xiàn)LED 的靜態(tài)顯示。采用了PIC16F877 的端口輸出操作，模擬74LS373 的數(shù)據(jù)鎖存時(shí)序，即由軟件實(shí)現(xiàn)數(shù)據(jù)鎖存，這種方法可以十分容易的改變時(shí)序和延遲長(zhǎng)短，使高速設(shè)備可以與低速設(shè)備聯(lián)系配合好，設(shè)計(jì)簡(jiǎn)單方便，不好的地方是編程較長(zhǎng)和稍微復(fù)雜一點(diǎn)。這種編程方法在下面的程序中有很好的體現(xiàn)。
