LCD1602数据手册LCD16...

LCD1602数据手册1602采用标准的16脚接口,其中:第1脚:VSS为地电源第2脚:VDD接5V正电源第3脚:V0为液晶显示器对比度调整端,接正电源时对比度最弱,接地电源时对比度最高,对比度过高时会产生“鬼影”,使用时可以通过一个10K的电位器调整对比度第4脚:RS为寄存器选择,高电平时选择数据寄存器、低电平时选择指令寄存器。
第5脚:RW为读写信号线,高电平时进行读操作,低电平时进行写操作。
当RS和RW共同为低电平时可以写入指令或者显示地址,当RS为低电平RW为高电平时可以读忙信号,当RS为高电平RW为低电平时可以写入数据。
第6脚:E端为使能端,当E端由高电平跳变成低电平时,液晶模块执行命令。
第7~14脚:D0~D7为8位双向数据线。
第15~16脚:空脚1602液晶模块内部的字符发生存储器(CGROM)已经存储了160个不同的点阵字符图形,如表1所示,这些字符有:阿拉伯数字、英文字母的大小写、常用的符号、和日文假名等,每一个字符都有一个固定的代码,比如大写的英文字母“A”的代码是01000001B(41H),显示时模块把地址41H中的点阵字符图形显示出来,我们就能看到字母“A”1602液晶模块内部的控制器共有11条控制指令,如表2所示,它的读写操作、屏幕和光标的操作都是通过指令编程来实现的。
(说明:1为高电平、0为低电平)指令1:清显示,指令码01H,光标复位到地址00H位置指令2:光标复位,光标返回到地址00H指令3:光标和显示模式设置 I/D:光标移动方向,高电平右移,低电平左移 S:屏幕上所有文字是否左移或者右移。
高电平表示有效,低电平则无效指令4:显示开关控制。
D:控制整体显示的开与关,高电平表示开显示,低电平表示关显示 C:控制光标的开与关,高电平表示有光标,低电平表示无光标 B:控制光标是否闪烁,高电平闪烁,低电平不闪烁指令5:光标或显示移位 S/C:高电平时移动显示的文字,低电平时移动光标指令6:功能设置命令 DL:高电平时为4位总线,低电平时为8位总线 N:低电平时为单行显示,高电平时双行显示 F: 低电平时显示5x7的点阵字符,高电平时显示5x10的点阵字符指令7:字符发生器RAM地址设置指令8:DDRAM地址设置指令9:读忙信号和光标地址 BF:为忙标志位,高电平表示忙,此时模块不能接收命令或者数据,如果为低电平表示不忙。

PRECAUTIONS FOR USING LCD MODULES9.1 PrecautionTo our module ,we have made accurately assembly and debugging .So customer should do as follows: (1)Modules use LCD elements, so we must be treated as such avoid intense shock 、impact 、 extrusion and falls from a height. (2)Avoid to twist and disassemble module’s buckle legs. (3)Avoid to operate modules on the table if it's surface have printed circuit (4)Avoid to touch 、adjust and modify the rubber that connects LCD and PCB. (5)Avoid to add DC(direct current) in module. (6)Liquid crystal is harmful Substances .When liquid crystal leaked out and contacted to your hand、body or clothes ,you must wash it immediately with soap.9.2 Caution Of MountingThe panel of the LCD module consists of two thin glass plates with polarizes which easily get damaged since the module is fixed by utilizing fitting holes in the printed circuit board. Extreme care should be taken when handling the LCD modules.9.3 Caution Of LCD Handling & CleaningWhen cleaning the display surface. Use soft cloth with solvent (recommended below) and wipe lightly. -Isopropyl alcohol -Ethyl alcohol Do not wipe the display surface with dry or hard materials that will damage the polarizes surface. Do not use the following solvent: -Water -Ketone - 27 -TSINGTEK DISPLAY CO.,LTDREV . BHC1624-B-LWH- Aromatics9.4 Caution Against Static ChargeThe LCD modules use COMS LSI drivers. So we recommend that you connect any unused input terminal to Vdd or Vss, do not input any signals before power is turned on and ground your body. work/assembly table. And assembly equipment to protect against static electricity. the following ways are recommended. (1) If you doesn't intend to mount,please don't take module from bag.The module's packaging bag is handled by antistatic technology. (2) If you intend to operate module that you must make sure your body is good grounding , keeping your body and module at the same level. (3) The operating equipment requires to good grounding , especially the driver .In order to avoid interference we must make sure good grounding and no leakage. (4) Each module have a protective film .It is used to avoid the polaroid LCD is scratched or polluted .Please peel off the Protective Film slowly ,or else will produce static . (5) The humidity range at workshop: 50 ~ 60% RH9.5 Current Protection DevicesModule was not equipped with current protection devices, so we must prepared the current protection devices for using.The proportion of DC voltage is as small as possible ,preferably no more than 50mV.Or else it will cause electrochemical reaction after a time .9.6Caution For Operation-It is indispensable to drive LCM within the specified voltage limit since the higher voltage than the limit shortens LCM life. -Response time will be extremely delayed at lower temperature than the operating temperature range and on the other hand at higher temperature LCD show dark color in them. However those phenomena do not mean malfunction or out of order with LCD, which will come back in the specified operating temperature range. -If the display area is pushed hard during operation. Some font will be abnormally displayed but it resumes normal condition after turning off once. -A slight dew depositing on terminals is a cause for Electro-chemical reaction resulting in terminal open circuit. Under the maximum operating temperature, 50%RH or less is required9.7 Caution For SolderingIf need soldering,we must notice as follows: ※ Except the connect position of INPUT and OUTPUT doesn’t allow to soldering. ※ Soldering iron required to be insulated. (1)Soldering Conditions: Iron Temperature : 280℃±10℃ Soldering Time: ﹤3-4S Soldering Materials: Low melting point, can be fully molten solder - 28 -TSINGTEK DISPLAY CO.,LTDREV . BHC1624-B-LWH(2)Caution for repeat soldering: Because connect line is through module's pad connected to module. Removing the line we must wait until the solder is completely melted . If solder doesn't completely melted , it is easily lead to the pad damage or ing “ XI QIANG” is the best way to remove the connect line .Besides, we must notice that repeat soldering doesn’t allow more than three time.9.8 Packaging And StorageWhen module needs to store a long time ,we should do as follows.If storage method is improper,it will have an effect on the Polaroid ,causing display not good.Meanwhile pads are easily oxidized lead to soldering didn't easily . (1)As far as possible to use the original packaging bag. (2)If we intend to store bulk modules ,we should put them in anti-static bag and sealing . (3)To prevent modules from degradation, do not operate or store them exposed directly to sunshine or high temperature/humidity. (4)The reasonable storage method is low humidity, temperature in 0℃ to 35℃ (5)Storing with no touch on polarizes surface by the anythingelse.10.PRECAUTIONS FOR CUSTOMER(1)A limit sample should be provided by the both parties on an occasion when the both parties agree its necessity.Judgement by a limit sample shall take effect after the limit sample has been established and confirmed by the both parties. (2) On the following occasions, the handling of problem should be decided through discussion and agreement between representative of the both parties. -When a question is arisen in this specification. -When a new problem is arisen which is not specified in this specifications. -When an inspection specification change or operating condition change in customer is reported to TSINGTEK, and some problem is arisen in this specification due to the change. -When a new problem is arisen at the customer’s operating set for sample evaluation in the customer size.- 29 -。
LCD1602帮助手册

LCD1602帮助手册正面图背面图正面图为第一图,管脚应排列在左上方,左边第一脚为管脚1,向右依次为2,3,4………15,16。
背面一般也有标注,并且附带了管脚对应的作用。
其中第三脚VO为对比度调节脚,一般外接滑动变阻器,调节输入的电压,来调节明暗度(可以直接接地,不过直接接地,需要斜着屏幕,才能看见LCD是否显示字符,正面看都是黑黑的一格一格的)。
15,16角一般为背光LED灯源,一个接VCC(一般为15脚),一个接GND(一般为16脚),最好接入限流电阻,不接也可使用,不过会缩短寿命,这两角可以不接,如果不接,在黑暗的室内,显示效果欠佳。
管脚编号如下图所示:管脚对应符号对LCD的操作,有四种操作,分别为:读状态,读数据,写指令和写数据,一般常用的为读状态,写指令和写数据。
操作图如下:当RS端为低电平,RW端为高电平,E为高电平是,对LCD1602的操作为读状态操作,这时,可以对LCD的状态进行读取,读取通过D0~D7的端口读取。
其他操作相似,对照图,即可完成,但是有个读写时序的要求,时序图见下图:读操作时序对LCD进行读操作时,先将RS置为低电平(0V),然后将RW样置为高电平(+5V),然后有个tsp1的延迟(但是一般这个延迟为ns级,一个单片机的指令周期通常都为us级,一般不需要特别延迟,如果程序有一定错误的时候,可以稍微延迟一下),然后再将E置为1,然后延迟td时间(td一般也为ns级,可以适当延迟一点点),然后读取D0~D7的数据。
写操作也是类似的,将RS,RW,E端口进行相应操作即可完成,写数据和写命令的操作,延迟的时间都很短,程序不稳定的话,可以延迟个1us,一般就可以了。
LCD1602的指令有11条,如下图:(指令表)从之前的操作来看,对照此表,不难看出,指令表的前8条都是命令指令,RS,RW都为0,所以操作时,都是写命令操作,D7~D0的数值的不同,代表了操作的不同,比如D0~D7为0x01时,对LCD的操作命令就为清屏显示,第二条指令为光标返回指令,在D0处有个※标记,这表示,不论此位的数据为1还是为0,对此命令都无效,即D0~D7端口写入0x20为光标返回指令,D0~D7端口写入0x03,此命令也为光标返回指令。

1602LCD主要技术参数:
显示容量:16*2个字符
芯片工作电压:4.5——5.5v
工作电流:2.0mA(5.0V)
模块最佳工作电压:5.0V
字符尺寸:2.95*4.35(W*H)mm
引脚功能说名
1602LCD采用标准的14脚(无背光)或16脚(带背光)接口,各引脚接口功能说明如下:编号符号引脚说明编号符号引脚说明、
1 VSS 电源地9 D
2 数据
2 VDD 电源正极10 D
3 数据
3 VL 液晶显示偏压11 D
4 数据
4 RS 数据/命令选择12 D
5 数据
5 R/W 读/写选择13 D
6 数据
6 E 使能信号14 D
7 数据
7 D0 数据15 BLA 背光源正极
8 D1 数据16 BLK 背光源负极
表10-13:引脚接口说明表
第1脚:VSS为地电源。
第2脚:VDD接5V正电源。
第3脚:VL为液晶显示器对比度调整端,接正电源时对比度最弱,接地时对比度最高,对比度过高时会产生“鬼影”,使用时可以通过一个10K的电位器调整对比度。
第4脚:RS为寄存器选择,高电平时选择数据寄存器、低电平时选择指令寄存器。
第5脚:R/W为读写信号线,高电平时进行读操作,低电平时进行写操作。
当RS和R/W 共同为低电平时可以写入指令或者显示地址,当RS为低电平R/W为高电平时可以读忙信号,当RS为高电平R/W为低电平时可以写入数据。
第6脚:E端为使能端,当E端由高电平跳变成低电平时,液晶模块执行命令。
第7~14脚:D0~D7为8位双向数据线。
第15脚:背光源正极。
第16脚:背光源负极。
1602LCD的指令说明及时序
1602液晶模块内部的控制器共有11条控制指令,如表10-14所示:

表10-14:控制命令表
1602液晶模块的读写操作、屏幕和光标的操作都是通过指令编程来实现的。
(说明:1为高电平、0为低电平)
指令1:清显示,指令码01H,光标复位到地址00H位置。
指令2:光标复位,光标返回到地址00H。
指令3:光标和显示模式设置I/D:光标移动方向,高电平右移,低电平左移S:屏幕上所有文字是否左移或者右移。
高电平表示有效,低电平则无效。
指令4:显示开关控制。
D:控制整体显示的开与关,高电平表示开显示,低电平表示关显示C:控制光标的开与关,高电平表示有光标,低电平表示无光标B:控制光标是否闪烁,高电平闪烁,低电平不闪烁。
指令5:光标或显示移位S/C:高电平时移动显示的文字,低电平时移动光标。
指令6:功能设置命令DL:高电平时为4位总线,低电平时为8位总线N:低电平时为单行显示,高电平时双行显示F: 低电平时显示5x7的点阵字符,高电平时显示5x10的点阵字符。
指令7:字符发生器RAM地址设置。
指令8:DDRAM地址设置。
指令9:读忙信号和光标地址BF:为忙标志位,高电平表示忙,此时模块不能接收命令或者数据,如果为低电平表示不忙。
指令10:写数据。
指令11:读数据。
