2、E信號(hào) | E狀態(tài) | | | | | 配合R/W進(jìn)行寫數(shù)據(jù)或指令 | | | 配合R進(jìn)行讀數(shù)據(jù)或指令 | | | |
● 忙標(biāo)志:BF BF標(biāo)志提供內(nèi)部工作情況.BF=1表示模塊在進(jìn)行內(nèi)部操作,此時(shí)模塊不接受外部指令和數(shù)據(jù).BF=0時(shí),模塊為準(zhǔn)備狀態(tài),隨時(shí)可接受外部指令和數(shù)據(jù). 利用STATUS RD 指令,可以將BF讀到DB7總線,從而檢驗(yàn)?zāi)K之工作狀態(tài). ● 字型產(chǎn)生ROM（CGROM） 字型產(chǎn)生ROM（CGROM）提供8192個(gè)此觸發(fā)器是用于模塊屏幕顯示開(kāi)和關(guān)的控制。DFF=1為開(kāi)顯示（DISPLAY ON),DDRAM 的內(nèi)容就顯示在屏幕上，DFF=0為關(guān)顯示（DISPLAY OFF)。 DFF的狀態(tài)是指令DISPLAY ON/OFF和RST信號(hào)控制的。 ● 顯示數(shù)據(jù)RAM（DDRAM） 模塊內(nèi)部顯示數(shù)據(jù)RAM提供64×2個(gè)位元組的空間，最多可控制4行16字（64個(gè)字）的中文字型顯示，當(dāng)寫入顯示數(shù)據(jù)RAM時(shí)，可分別顯示CGROM與CGRAM的字型；此模塊可顯示三種字型，分別是半角英數(shù)字型(16*8)、CGRAM字型及CGROM的中文字型，三種字型的選擇，由在DDRAM中寫入的編碼選擇，在0000H—0006H的編碼中（其代碼分別是0000、0002、0004、0006共4個(gè)）將選擇CGRAM的自定義字型，02H—7FH的編碼中將選擇半角英數(shù)字的字型，至于A1以上的編碼將自動(dòng)的結(jié)合下一個(gè)位元組，組成兩個(gè)位元組的編碼形成中文字型的編碼BIG5（A140—D75F），GB（A1A0-F7FFH）。 ● 字型產(chǎn)生RAM(CGRAM) 字型產(chǎn)生RAM提供圖象定義(造字)功能, 可以提供四組16×16點(diǎn)的自定義圖象空間，使用者可以將內(nèi)部字型沒(méi)有提供的圖象字型自行定義到CGRAM中，便可和CGROM中的定義一樣地通過(guò)DDRAM顯示在屏幕中。 ● 地址計(jì)數(shù)器AC 地址計(jì)數(shù)器是用來(lái)貯存DDRAM/CGRAM之一的地址,它可由設(shè)定指令暫存器來(lái)改變，之后只要讀取或是寫入DDRAM/CGRAM的值時(shí)，地址計(jì)數(shù)器的值就會(huì)自動(dòng)加一，當(dāng)RS為“0”時(shí)而R/W為“1”時(shí)，地址計(jì)數(shù)器的值會(huì)被讀取到DB6——DB0中。 ● ● 光標(biāo)/閃爍控制電路 此模塊提供硬體光標(biāo)及閃爍控制電路，由地址計(jì)數(shù)器的值來(lái)指定DDRAM中的光標(biāo)或閃爍位置。 五、指令說(shuō)明 模塊控制芯片提供兩套控制命令，基本指令和擴(kuò)充指令如下： 指令表1：（RE=0：基本指令） | | | | | | | | | | | | | | | | | | | | | | | | | | 將DDRAM填滿"20H",并且設(shè)定DDRAM的地址計(jì)數(shù)器(AC)到"00H" | | | | | | | | | | | | 設(shè)定DDRAM的地址計(jì)數(shù)器(AC)到"00H",并且將游標(biāo)移到開(kāi)頭原點(diǎn)位置;這個(gè)指令不改變DDRAM 的內(nèi)容 | | | | | | | | | | | | D=1: 整體顯示 ON C=1: 游標(biāo)ON B=1:游標(biāo)位置反白允許 | | | | | | | | | | | | 指定在數(shù)據(jù)的讀取與寫入時(shí),設(shè)定游標(biāo)的移動(dòng)方向及指定顯示的移位 | | | | | | | | | | | | 設(shè)定游標(biāo)的移動(dòng)與顯示的移位控制位;這個(gè)指令不改變DDRAM 的內(nèi)容 | | | | | | | | | | | | DL=0/1：4/8位數(shù)據(jù) RE=1: 擴(kuò)充指令操作 RE=0: 基本指令操作 | | | | | | | | | | | | | | | | | | | | | | | | 設(shè)定DDRAM 地址（顯示位址） 第一行：80H－87H 第二行：90H－97H | | | | | | | | | | | | 讀取忙標(biāo)志(BF)可以確認(rèn)內(nèi)部動(dòng)作是否完成,同時(shí)可以讀出地址計(jì)數(shù)器(AC)的值 | | | | | 將數(shù)據(jù)D7——D0寫入到內(nèi)部的RAM (DDRAM/CGRAM/IRAM/GRAM) | | | | | 從內(nèi)部RAM讀取數(shù)據(jù)D7——D0 (DDRAM/CGRAM/IRAM/GRAM) |
指令表2：（RE=1：擴(kuò)充指令） | | | | | | | | | | | | | | | | | | | | | | | | | | 進(jìn)入待命模式,執(zhí)行其他指令都棵終止 待命模式 | 卷動(dòng)地址開(kāi)關(guān)開(kāi)啟 | | | | | | | | | | | SR=1：允許輸入垂直卷動(dòng)地址 SR=0：允許輸入IRAM和CGRAM地址 | | | | | | | | | | | | 選擇2行中的任一行作反白顯示，并可決定反白與否。初始值R1R0＝00，第一次設(shè)定為反白顯示，再次設(shè)定變回正常 | | | | | | | | | | | | SL=0：進(jìn)入睡眠模式 SL=1：脫離睡眠模式 | | | | | | | | | | | | CL=0/1：4/8位數(shù)據(jù) RE=1: 擴(kuò)充指令操作 RE=0: 基本指令操作 G=1/0：繪圖開(kāi)關(guān) | | | | | | | | | | | | 設(shè)定繪圖RAM 先設(shè)定垂直(列)地址AC6AC5…AC0 再設(shè)定水平(行)地址AC3AC2AC1AC0 將以上16位地址連續(xù)寫入即可 |
備注;當(dāng)IC1在接受指令前,微處理器必須先確認(rèn)其內(nèi)部處于非忙碌狀態(tài),即讀取BF標(biāo)志時(shí),BF需為零,方可接受新的指令;如果在送出一個(gè)指令前并不檢查BF標(biāo)志,那么在前一個(gè)指令和這個(gè)指令中間必須延長(zhǎng)一段較長(zhǎng)的時(shí)間,即是等待前一個(gè)指令確實(shí)執(zhí)行完成。

25oC, VDD = 4.5 V - 5.5 V） 八、軟件初始化 file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image010.gif file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image011.gif 九．應(yīng)用舉例： 1 、使用前的準(zhǔn)備 先給模塊加上工作電壓，再按照下圖的連接方法調(diào)節(jié)LCD的對(duì)比度，使其顯示出黑色的底影。 此過(guò)程亦可以初步檢測(cè)LCD有無(wú)缺段現(xiàn)象。 2、字符顯示 12864C-1每屏可顯示4行8列共32個(gè)16×16點(diǎn)陣的漢字，每個(gè)顯示RAM可顯示1個(gè)中 file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image012.jpg 文字符或2個(gè)16×8點(diǎn)陣全高ASCII碼字符，即每屏最多可實(shí)現(xiàn)32個(gè)中文字符或64個(gè)ASCII碼字符的顯示。12864C-1內(nèi)部提供128×2字節(jié)的字符顯示RAM緩沖區(qū)（DDRAM）。字符顯示是通過(guò)將字符顯示編碼寫入該字符顯示RAM實(shí)現(xiàn)的。根據(jù)寫入內(nèi)容的不同，可分別在液晶屏上顯示CGROM（中文字庫(kù)）、HCGROM（ASCII碼字庫(kù)）及CGRAM（自定義字形）的內(nèi)容。三種不同字符/字型的選擇編碼范圍為：0000～0006H（其代碼分別是0000、0002、0004、0006共4個(gè)）顯示自定義字型，02H～7FH顯示半寬ASCII碼字符，A1A0H～F7FFH顯示8192種GB2312中文字庫(kù)字形。字符顯示RAM在液晶模塊中的地址80H～9FH。字符顯示的RAM的地址與32個(gè)字符顯示區(qū)域有著一一對(duì)應(yīng)的關(guān)系，其對(duì)應(yīng)關(guān)系如下表所示。 3 、圖形顯示 先設(shè)垂直地址再設(shè)水平地址(連續(xù)寫入兩個(gè)字節(jié)的資料來(lái)完成垂直與水平的坐標(biāo)地址) 垂直地址范圍 AC5...AC0 水平地址范圍 AC3…AC0 繪圖RAM 的地址計(jì)數(shù)器（AC）只會(huì)對(duì)水平地址(X 軸)自動(dòng)加一,當(dāng)水平地址=0FH 時(shí)會(huì)重新設(shè)為00H 但并不會(huì)對(duì)垂直地址做進(jìn)位自動(dòng)加一，故當(dāng)連續(xù)寫入多筆資料時(shí)，程序需自行判斷垂直地址是否需重新設(shè)定。GDRAM的坐標(biāo)地址與資料排列順序如下圖 file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_image013.jpg 3、應(yīng)用說(shuō)明 用12864C-1顯示模塊時(shí)應(yīng)注意以下幾點(diǎn)： ①欲在某一個(gè)位置顯示中文字符時(shí)，應(yīng)先設(shè)定顯示字符位置，即先設(shè)定顯示地址，再寫入中文字符編碼。 ②顯示ASCII字符過(guò)程與顯示中文字符過(guò)程相同。不過(guò)在顯示連續(xù)字符時(shí)，只須設(shè)定一次顯示地址，由模塊自動(dòng)對(duì)地址加1指向下一個(gè)字符位置，否則，顯示的字符中將會(huì)有一個(gè)空ASCII字符位置。 ③當(dāng)字符編碼為2字節(jié)時(shí)，應(yīng)先寫入高位字節(jié)，再寫入低位字節(jié)。 ④模塊在接收指令前，向處理器必須先確認(rèn)模塊內(nèi)部處于非忙狀態(tài)，即讀取BF標(biāo)志時(shí)BF需為“0”，方可接受新的指令。如果在送出一個(gè)指令前不檢查BF標(biāo)志，則在前一個(gè)指令和這個(gè)指令中間必須延遲一段較長(zhǎng)的時(shí)間，即等待前一個(gè)指令確定執(zhí)行完成。指令執(zhí)行的時(shí)間請(qǐng)參考指令表中的指令執(zhí)行時(shí)間說(shuō)明。⑤“RE”為基本指令集與擴(kuò)充指令集的選擇控制位。當(dāng)變更“RE”后，以后的指令集將維持在最后的狀態(tài)，除非再次變更“RE”位，否則使用相同指令集時(shí)，無(wú)需每次均重設(shè)“RE”位。
