八:指令说明
1. 指令表

2. 基本指令详解 (1).概述 此款中文液晶显示模块是一个中英文文字与绘图模式的点矩阵液晶显示模块,内建 512KByte 的 ROM 字形码, 可以显示中文字型、 数字符号、 英日欧文等字母, 并且内建双图层(Two Page) 的显示内存。在文字模式中,可接收标准中文文字内码直接显示中文,而不需要进入绘图模式 以绘图方式描绘中文,可以节省许多微处理器时间,提升液晶显示中文之处理效率。 支持文字与绘图两种混和显示模式支持 2 Page 显示模式(And, Or, Nor, Xor),内建两个 4.8K / 9.6 K(15x20D) Byte 的显示 RAM (Display DataRAM),共 9.6K / 19.2 K(15x20D) Byte RAM,并且可做成 4 阶的显示效果。内建 512KByte ROM,控制 IC 分带繁体字库 IC 和带简体字库 IC,其中标准体中文 BIG5 码,包含 13,094 个常用与次常用字型、408 个特 殊字与两组 ASCII CODE,简体字库储存 7602 个标准 GB 码的简体中文。 提供全角(16x16)与半角(8x16)文字显示模式 支持 4/8 位之 6800/8080 MCU 接口 带光标、反白、闪烁功能,且光标高度与宽度可调 支持屏幕水平卷动及垂直卷动功能 内建 512Byte SRAM 可自行造字 提供中/英文文字对齐功能 显示字型可放大到 32x32、48x48 或 64x64,以及混合显示模式 支持可将字型由 ROM 直接读出使用 内建粗体字形与行距设定 (2).功能应用介绍 2.1 Wakeup 的程序 当 REG[00]之 bit7-6 为”00”,则进入关闭模式(OFF MODE),若是要做唤醒的动作(Wake-UP), 此时可使用三种方式,将中文液晶显示模块唤醒。 1,利用 MCU 将缓存器[00]的 bit7-6 再设定为”11”,就可回到正常模式(Normal Mode) 。 2.Touch Panel 中断功能(OCMJ4X15D 与 OCMJ5X10D 已屏蔽此功能): 设定缓存器[A0]的 bit2 为”1”及缓存器[C0]的 bit3=”1”,当整个系统进入 OFF-mode 之后,若此 时有任何触控屏幕的动作,则模块将产生中断讯号 INT 由”0”到”1”的变化,此控制讯号可连接 至微处理机做其它动作的延续。缓存器设定方法可参考下面程序 unsigned char intr= Lcd_regread (0xA0) | 0x04 ; unsigned char tpcr= Lcd_regread (0xC0) & 0xf8 ; tpcr |= 0x80; Lcd_regwrite (0xA0,intr); // REG[A0]:bit2=1 Lcd_regwrite (0xC0,tpcr); // REG[C0]:bit[3..0]=1000 : : 2.2 文字模式功能

此款中文液晶显示模块的文字模式可以支持全角(中文或英文)及半角(英文)的显示,全角文字 是以 16x16 的点矩阵组成,半角文字是 8x16 的点矩阵组成,如图 1-1 所示,而图 1-2 是全 角(中文)及半角(英文)文字的混和显示:

图 1-1:全角与半角文字

图 1-2:全角与半角文字的混合显示 此款中文液晶显示模块的中文显示方式与一般的模块不同,一般的模块是在绘图模式下,以 Bit-Map 的方式去绘出中文,此款中文液晶显示模块的中文显示方式则是在文字模式,直接输 入中文字码(GB 或BIG5码) ,就可以在光标所在位置显示中文。因为中文字码占两个Byte,所 以如果MCU 接口是8-Bit, 则MCU 必须分两次将中文字码的High Byte & Low Byte)写入此款中 文液晶显示模块,而英文或数字码只占一个Byte,因此只要将内码一次写入此款中文液晶显示 模块既可。表1-1为图1-2 所示之全角(中文)与半角文字的字型码,下面例题程序就是说明如何 显示图5-2 的画面。 表 1-1:文字码的对照表(BIG5)

例题: MOV A,#A4H ; 写入“中” 的字型码 High Byte CALL DDR_WRITE MOV A,#A4H ; 写入“中” 的字型码 Low Byte CALL DDR_WRITE ; 在光标所在位置会显示“中” MOV A,#A4H ; 写入“文” 的字型码 High Byte CALL DDR_WRITE MOV A,#E5H ; 写入“文” 的字型码 Low Byte CALL DDR_WRITE ; 在光标所在位置会显示“文” : : 2.3 粗体字之显示功能 此款中文液晶显示模块的中英文显示都可以秀出粗体字的显示效果,设定缓存器[10]的 bit4 为”1”就可以显示粗体文字。

2.4 绘图模式设定 此款中文液晶显示模块的绘图模式是以字符映像(bit map)方式填入图形资料在Display RAM 上, 图1-3 说明进入绘图模式时,缓存器要如何设定:

图1-3:绘图模式的显示

当此款中文液晶显示模块在显示图形的时候,是以字符映像(Bit Map)的方式写入DDRAM,若 DDRAM 的某个位置被填满为‘1’ 时, 相对于LCD 面板的位置会被显示出亮点, 由图1-4 可看出, 在DDRAM 上所储存之像素资料,会对应到显示屏幕(LCD)上,而构成文字、符号或图形之显示 效果。

图1-4:Display Data 到LCD 显示的映射 以下程序就是以图5-4 做例子,用绘图模式在LCD 的左上角秀出图形: 例题:(8051-ASM) MOV A, #60h ; 选择光标设定缓存器(CPXR) CALL REG_WR MOV A, #00h ; 设定坐标X=0 CALL REG_WR MOV A, #70h ; 选择光标设定缓存器(CPYR) CALL REG_WR MOV A, #00h ; 设定坐标Y=0 CALL REG_WR ; 设定光标位置为(0,0) MOV A,#E6H ;在LCD 的左上角秀出“E6” 的图形

CALL DDR_WRITE 例题:(8051-C) Lcd_regwrite(0x60,0x00); // 设定坐标X=0 Lcd_regwrite(0x70,0x00); // 设定坐标Y=0 Lcd_datawrite(0xE6); //在LCD 的左上角秀出“E6” 的图形 在绘图模式下, 缓存器[12h]的Bit7 用来选择光标的移动是先水平移动再垂直移动或是先垂直移动再 水平移动, 如图1-5。

图1-5:选择光标的移动 图1-6 范例: MOV A, #12h ; 选择缓存器 [12h] (MAMR) CALL REG_WR MOV A, #91h ; Bit7=1, 先水平移动再垂直移动 CALL REG_WR MOV A,#11H ;在LCD Panel 的左上角秀出 “11” 的图形Pattern CALL DDR_WRITE MOV A,#22H ;在LCD Panel 的左上角秀出 “22” 的图形Pattern CALL DDR_WRITE MOV A,#33H ;在LCD Panel 的左上角秀出 “33” 的图形Pattern CALL DDR_WRITE MOV A,#44H ;在LCD Panel 的左上角秀出 “44” 的图形Pattern CALL DDR_WRITE

图1-6:光标先水平移动再垂直移动 图1-7 范例: MOV A, #12h ; 选择缓存器 [12h] (MAMR) CALL REG_WR MOV A, #11h ; Bit7=0, 先垂直移动再水平移动 CALL REG_WR MOV A,#11H ;在LCD Panel 的左上角秀出 “11” 的图形Pattern CALL DDR_WRITE MOV A,#22H ;在LCD Panel 的左上角秀出 “22” 的图形Pattern CALL DDR_WRITE MOV A,#33H ;在LCD Panel 的左上角秀出 “33” 的图形Pattern CALL DDR_WRITE MOV A,#44H ;在LCD Panel 的左上角秀出 “44” 的图形Pattern CALL DDR_WRITE

图1-7:光标先垂直移动再水平移动 在绘图模式下,若要读取Display RAM 的数据时,也是由缓存器[12h]的Bit7 用来选择光标的移动 是先水平移动再垂直移动或是先垂直移动再水平移动,如图1-5。不论写入或读取Display RAM 的

数据都必须注意光标的设定是否有自动加一的功能, 也就是缓存器[10h]的Bit7 与Bit3。 如图1-8 是 代表缓存器[12h]Bit7=1( 先水平移动再垂直移动)时Display RAM 数据的读取方向。

图1-8:图形模式时资料读取方向 2.5 闪烁与反白显示 2.5.1 闪烁显示 图 1-9 说明要闪烁显示时,缓存器要如何设定

图 1-9:屏幕闪烁

2.5.2 屏幕反白 如果要将 LCD 画面全部反白只要设定缓存器[00h] 的 Bit0 既可。

2.5.3 文字反白 如果要将LCD 画面秀出反白的字体只要设定缓存器[10h]的Bit5 既可, 图1-10 说明要反白显示时, 缓存器要如何设定:

(a) 1. 设定缓存器[10h] bit5=0 2. 写入"中文文字/圖形LCD 控制器"的BIG5 码,然后可显示出"中文文字/圖形LCD 控制器" (b) 3. Hold on (a) 4. 设定缓存器[10h] bit5=1

5. 写入"文字"的BIG5 码,LCD 就可显示出"文字" 6. Hold on 7. 设定缓存器[10h] bit5=0 8. 写入"反白"的BIG5 码,LCD 就可显示出"反白" 9. Hold on 10. 设定缓存器[10h] bit5=1 11. 写入"功能”的BIG5 码,LCD 就可显示出"功能"

2.6 中/英文文字对齐 由于英文字体与中文字体所占的宽度不一样, 因此在显示中文英文都有的画面时必须考虑整体显示效 果,此款中文液晶显示模块可以设定中文英文显示时不同行的显示效果以决定文字是否对齐,图1-11 说明要表现出中英文文字“对齐” 之情形时,缓存器要如何设定: 1. 设定REG[10h] bit6 = 1 2. 写入“中文文字/圖形LCD 控制器” 两次,则屏幕会秀出” 中文文字/圖形LCD 控制器” ――上下两行文字对齐

图1-11:文字对齐的显示范例

图1-12 说明要表现出中英文文字“不对齐” 之情形时,缓存器要如何设定: 1. 设定REG[10h] bit6 = 1 2. 写入“中文文字/圖形LCD 控制器” 3. 设定REG[10h] bit6 = 0 4. 写入“中文文字/圖形LCD 控制器” ――上下两行文字没对齐

图1-12:文字不对齐的显示范例 2.7 LCD 屏幕显示 On/Off 设定

2.8 光标 On/Off 设定

2.9 光标位置与移位设定 2.9.1 光标位置 缓存器[60h]CPXR 的Bit[5..0]用来设定光标的Segment 地址,光标的Segment 地址是以每 8-Bit 为单位, 例如, 想在屏幕的左上角秀出“控” , 则必须设定光标缓存器CPXR = 00h, CPYR = 00h,又例如想在屏幕的左上角第三个全角位置秀出“制” ,则必须设定光标缓存器CPXR = 04h,CPYR = 00h,同理,想在屏幕的左上角第二行第一个全角位置秀出“器” ,则必须设定 光标缓存器CPXR = 00h,CPYR = 10h,请参考图1-13。

图1-13:光标位置设定的显示范例

不论文字或是绘图模式,都是使用缓存器[60h]CPXR 与[70h]CPYR 来设定光标的地址。缓 存器[60h]CPXR 与[70h]CPYR 的光标地址是属于绝对地址,不会因工作窗口大小而改变,也 就是(0 ,0)始终是在屏幕的左上角。 2.9.2 光标移位

2.10

光标闪烁设定

如果Frame Rate = 60Hz,则1/Frame_Rate = 1/60Hz = 1.67ms,光标闪烁时间= REG[80h] x1.67ms,例如设定REG[80h] = 35h = 53(十进制),因此光标闪烁时间= 53 x 16.7ms = 885ms。 2.11 光标高度与宽度设定 2.11.1 光标高度 此款中文液晶显示模块在做文字显示时,有提供光标高度的设定,在正常显示文字时,光标的 高度为一个点阵行的高度,但依不同使用者的需要,提供了光标的高度设定,光标的高度设定 范围为(1~16)点阵行,使用者可依需求来决定光标的高度大小。 注:光标的底端是在文字的下一点阵行,当光标的高度设为 1 时,最后那行文字会没光标。

2.11.2 光标宽度 此款中文液晶显示模块在做文字显示时, 有提供两种光标宽度的设定。 第一种为REG[10h] bit0=0 时,光标的宽度将会固定为1 个Byte 的宽度(也就是8 个点阵列)。第二种为REG[10h] bit0=1 时,光标的宽度会随着所输入文字来做变化,例如当输入一个全角字时,文字后面的光标宽度会

自动变为2 个Byte(也就是16 个点阵列)。当输入一个半角字时,文字后面的光标宽度会自动变 为1 个Byte。

2.12 工作及显示窗口大小设定 此款中文液晶显示模块供使用者有两种窗口选择。一个是显示窗口(Display Window),一个是 工作窗口(ActiveWindow)。显示窗口(Display Window)是实际LCD 面板的大小,而工作窗口 (Active Window)是在实际的显示窗口(Display Window)内设定比显示窗口小的子窗口。例如面板 大小为240x64,而它的显示窗口就为240x64。在显示窗口(240x64) 内可依使用者需要,来设定 工作窗口的大小,也就是子窗口的大小,子窗口也可在显示窗口内任意调整所要放置的地方。以 下是相关的缓存器说明:

注:光标地址应设定在显示窗口的范围内,因此缓存器[60h, 70h]、[B0h, B1h]与[21h, 31h, 41h

, 51h]的设定必须遵照以下的规范: 1. AWRR≧CPXR≧AWLR, AWRR≧INTX≧AWLR 2. AWBR≧CPYR≧AWTR, AWBR≧INTY≧AWTR

注:REG [20h, 30h, 40h, 50h] 可作为换行/换页的功能,可让使用者利用这4 个Register 自行 设定一个区块为工作窗口(Active Window)。当资料超过窗口的右边界REG [20h, 30h, 40h, 50h] 所设定的值,光标会自动换行(也就是光标移到工作窗口的左边界REG[40h]所设定的值),继续 将资料写入。当资料写入到工作窗口的右下角时(REG[20h]与[30h]所设定的值),会自动把光 标移到工作窗口的的左上角(REG[40h, 50h]所设设定完工作窗口后, 光标地址不会自动移到工作 窗口的范围内, 因为缓存器[60h]CPXR 与[70h]CPYR 的光标地址是属于绝对地址, 不会因工作 窗口大小而改变,也就是(0 ,0)始终是在屏幕的左上角,因此设定完工作窗口后想要进行秀字, 必须先将光标地址设定在工作窗口的范围内,之后光标地址就只会在工作窗口的范围内移动。 2.13 行距设定 此款中文液晶显示模块在做文字显示时,提供了行距设定的功能,尤其是做中文显示时,每一行 如果有适当的间隔,LCD的显示画面看起来会比较舒适。行与行相隔的间距设定范围为1~16点 阵行,使用者可依需求来决定行与行间距的大小,一旦设定后,当每填完一行的中文字,跳到下 一行时,其行距会依照先前所设定的间距来显示。

2.14

自动填入资料到 DDRAM

2.15

屏幕更新频率设定

例: 若设定SCLK = 8MHZ SCCR = ( 8MHZ x 4 ) / ( 320 x 240 x70 ) = 6 2.16 建议设定 SCCR = 6 = 06H 中断(Interrupt)与忙碌(Busy)设定

2.17

省电模式

2.18 字型放大设定 此款中文液晶显示模块内建有512KByte 的中文显示字型ROM(Font ROM),全角16x16 中 文与8x16 的ASCII半型字型。除了内建的8x16 和16x16 的字号外,还提供字型放大的功能, 可利用REG[F1h]bit7~4 的设定,将显示字号放大到32x32 或48x48,64x64。下图是表示16x 16 的字型放大到32x32。

2.19 图层显示功能设定 此款中文液晶显示模块提供了双图层的功能,可经由缓存器REG[12h]来做设定,并提供4 种(OR,NOR,XOR和AND)图层显示模式,供使用者设定选用。实际的显示效果,请参考 图1-17。

图1-17:图层显示效果

2.20 灰阶显示 此款中文液晶显示模块可利用分时显示的原理达到灰阶显示的效果,灰阶模式需要同时使用 Page1 和Page2的图层,在此模式下LCD 每一个点的灰阶效果决定于Display RAM Page1 与Page2 的值。对LCD 的同一点来说,[Page1, Page2] 可以为[0,0]、[1,0]、[0,1]、或 [1,1], 如果它们的显示不同将会产生不同的灰度效果,由于是利用分时显示的原理,为了达到良好的 显示质量及避免闪烁必须将Frame Rate 或系统频率提高。

PNTR = 55h, AAh, 0Fh, F0h, CCh, 33h 或99h 皆表示缓存器Data 中 “1” 和 “0” 的数目一样, 那么灰阶Level2与Level3 的显示效果是一样的,如果设成这些值只能有3 阶的显示效果,必须 让 ”1” 的数目多于 “0” 的数目才能有4 灰阶显示的效果。图1-18 是在屏幕上秀出四灰阶的基本 概念,如果Display RAM 的Page1 上半部全部填”00”,下半部全部填”FF”,且Page2 的左半部 全部填”00”,右半部全部填”FF”,那么启动灰阶功能后可以在屏幕上秀出四个不同灰阶的方块。

2.21 屏幕水平移动及垂直卷动设定 在屏幕所显示的画面可以作水平卷动,须由缓存器[03h]来做设定。该项功能可达到左右的水平卷 动,每次移动的刻度为1 个Byte。另外,还可透过缓存器[71h, 72h]来设定屏幕的区块水平卷动

2.22 ASCII 区块选择设定 此款中文液晶显示模块内建四个ASCII 区块,包含许多文字、特殊符号或图形等,可供使用者 直接取用,此功能可以由缓存器[F0h]的bit[1..0]来设定。下面我们将介绍这四个区块的Pattern (如图1-22~1-25) 及选择方式。

十:使用注意事项
十分感谢您购买我公司的产品,在使用前请您首先仔细阅读以下注意事项,以免给您造成不必 要的损失,您在使用过程中遇到困难时,请拨打我们的服务电话,我们将尽力为您提供服务和帮助。 1.处理保护膜 在装好的模块成品表面贴有一层保护膜,以防在装配时沾污显示表面,在整机装配结束前不得撕去 以免弄脏或损坏表面。 2.加装衬垫 在模块和前面板之间最好加装一块约0.1 毫米左右的衬垫。面板还应保持平整,以免在装配后产生

扭曲,并可提高其抗振性能。 3.严防静电 模块中的控制、驱动电压是很低、微功耗的CMOS 电路,极易被静电击穿,静电击穿是一种不可修 复的损坏,而人体有时会产生高达几十伏或上百伏的静电,所以,在操作、装配以及使用中都应极 其小心,严防静电。为此: (1) 不要用手随意去摸外引线、电路板上的电路及金属框。 (2) 如必须直接接触时,应使人体与模块保持在同一电位,或使人体良好接地。 (3) 焊接使用的烙铁及装配使用的电动工具必须良好接地,没有漏电。 (4) 不得使用真空吸尘器进行清洁处理,因为它会产生很强的静电。 (5) 空气干燥也会产生静电,因此,工作间湿度应在RH60%以上。 (6) 取出或放回包装袋或移动位置时,也需小心,防止产生静电。不要随意更换包装或舍弃原包装。 4.装配操作时的注意事项 (1) 模块是经过精心设计组装而成的,请勿随意自行加工、修整。 (2) 金属框爪不得随意扭动、拆卸。 (3) 不要随意修改加工PCB 板外形、装配孔、线路及其部件。 (4) 不得修改导电胶条。 (5) 不得修改任何内部支架。 (6) 不要碰、摔、折曲、扭动模块。 5.焊接 在焊接外引线时,应按如下规程进行操作。 (1) 烙铁头温度小于280 度。 (2) 焊接时间不超过4 秒。 (3) 焊接材料:共晶型、低熔点。 (4) 不要使用酸性助焊剂。 (5) 重复焊接不要超过三次,且每次重复需间隔5 分钟。 6.模块的使用与保养 (1) 模块的外引线决不允许接错,在您想调试液晶模块时,请注意正确接线,尤其是正负电源的接 线不能接错,否则可能造成过流、过压烧电路上的芯片等对液晶模块元器件有损的现象。 (2) 模块在使用时,接入电源及断开电源,必须在正电源稳定接入以后才能输入信号电平。如在电 源稳定前或断开后输入信号电平,有可能损坏模块中的IC 及电路。 (3) 点阵液晶模块显示时的对比度、视角与温度、驱动电压的关系很大,所以,如果驱动电压过高,不 仅会影响显示效果,还会缩短模块的使用寿命。 (4) 因为液晶材料的物理特性,液晶的的对比度会随温度的变化而相应变化,所以,您加的负压也 应随温度作相应调整。大致是温度变化10 度,电压变化1 伏。为满足这一要求,您可以做一个温 度补偿电路,或者安排一个电位器,随温度调整负电压值。 (5) 不应在规定工作温度范围外使用,并且不应在超过存储极限温度的范围外存储。如果温度低于 结晶温度,液晶就会结晶,如果温度过高,液晶将变成各向同性的液晶,破坏分子取向,使器件报废。 (6) 用力按显示部分,会产生异常显示。这时切断电源,稍待片刻重新上电,即恢复正常。

(7) 液晶显示器件或模块表面结雾时,不要通电工作,因为这将引起电极化学反应,产生断线。 (8) 长期用于阳光及强光下时,被遮部分会产生残留现象。 7.模块的存储 若长期(如几年以上)存储,我们推荐以下方式: (1) 装入聚乙稀口袋(最好有防静电涂层)并将口封住 (2) 在-10°C --- +35°C 之间存储。 (3) 放在暗处,避强光。 (4) 决不能在表面压放任何物品。 (5) 严格避免在极限温度/湿度条件下存放。 保修是以上述注意事项未被忽视为先决条件的,典型的违反例子如下: (1)断裂的液晶显示屏玻璃。 (2)线路板孔修改或损坏。 (3)线路板布线损坏。 (4)电路修改,包括元件的增加。 (5)线路板随意研磨、雕刻或油漆。 (6)焊接或更改玻璃框。 模块维修将基于双方协议下列出给顾客的清单。模块必须与防静电包装和故障详细陈述一起送回。 顾客安装的连接器或电缆必须坏线路板孔,线路和引线端条件下全部移去在不破坏线路板孔,线路 和引线端条件下全部移去。
