LCD12864显示实时时钟例程可运行

DS1302是美国DALLAS公司推出的一种高性能、低功耗的实时时钟芯片，附加31字节静态RAM，采用SPI三线接口与CPU进行同步通信，并可采用突发方式一次传送多个字节的时钟信号和RAM数据。

实时时钟可提供秒、分、时、日、星期、月和年，一个月小与31天时可以自动调整，且具有闰年补偿功能。

FPGA实现12864液晶的静-动态显示

FPGA实现12864液晶的静\动态显示摘要本文使用FPGA技术实现,通过控制液晶屏的地址,将汉字、字符或图形输入到液晶屏上,通过连续几屏显示实现动态效果。

关键词FPGA;12864lcd;静态显示;动态显示1 芯片和液晶屏介绍本实验所用芯片为ALTERA公司开发的EP1C6Q240C8芯片,cyclone系列,具有240个引脚,工作时最多可同时处理10路控制信号,工作电压为1.4V~3.6V。

液晶屏为12864,显示类型STN ,点阵格式128 x 64 ,点尺寸0.48 x 0.48mm 。

软件编程环境:Altera的Quartus II。

2 焊接板子,原理图如下左侧为EP1C6Q240C8芯片:共有240个引脚,相当于把4块芯片联系在一起,备选的引脚比较多。

右侧为液晶屏引脚,本液晶屏内置汉字库(通过查汉字编码库,得到代码)。

3 静态显示的设计3.1 给data_buffer赋内容constant data_buf0:data_buffer:=(x”a3”,x”c6”,x”a3”,x”d0”,//显示:fpgax”a3”,x”c7”,x”a3”,x”c1”,”x”20”,x”20”,x”20”,x”20”,x”20”,x”20”,x”20”,x”20”);// x”20”代表空格constant data_buf1:data_buffer:=(x”cd”,x”f5”,x”cf”,x”d4”,//显示:王显03x”a3”,x”b0”,x”a3”,x”b3”,x”20”,x”20”,x”20”,x”20” ,x”20”,x”20”,x”20”,x”20”);constant data_buf2与constant data_buf3所赋值均为x”20”,由图片可知,后两行并未输出内容。

x”20”代表空格,即此处不输入内容。

也可根据需要,通过查汉字编码表输入内容。

3.2 分频部分process(clk) //使用晶振为50MHZvariable cnt:integer range 0 to 499;//100k分频我们静态显示的频率是100kbeginif clk=‘1’ and clk’event thenif cnttemp=499 then cnttemp:=0;elseif cnttemprwcnt_1:=cnt_1+1;//此部分也是对液晶初始化。

12864液晶电子时钟+温度显示

12864液晶电子时钟+温度显示上午花了一上午时间，用12864 液晶写了一个电子时钟加温度传感器程序，先说一下程序的功能，可以实现显示年月日时间和温度，年月日和时间是可通过按键调节的，调节相应的选项时，该选项会闪烁，并停止走时，当调节完毕后时钟恢复走时。

现在将程序和思路写下来，以便日后查看和与大家探讨改进，欢迎高手提出宝贵意见。

我使用的是HJ12864M-1 带字库液晶，所以在显示上稍微方便一点。

下面先来说一下我的编程思路。

时间更新用的是单片机自带的定时器，液晶要显示数字必需将它转换成ASCii 码的形式，数字0-9 的ASCii 码与数字之间有一个定量的关系，当数字加上0x30 之后便得到该数字的ASCii 码，这样以来液晶更新数据就变得简单了。

调节时间时对应选项闪烁，是通过不断的交替写入数据和空格实现的。

温度显示用的是DS18B20,,将测得的当前温度不断更新显示在液晶上。

调节时间用的是三个独立按键。

由于这个程序我使用模块化来写的，就只能将每个模块分别给出来，大家只要组装一下便可以使用。

如果需要完整程序的可以给我留言我发给你们。

传动系
传动系是将原动系的能量传至擒纵调速器的一组传动齿轮，它是由二轮(中心轮)、三轮 (过轮)、四轮(秒轮)和擒纵轮齿轴组成，其中轮片是主动齿轮，齿轴是从动齿轮。钟表传动系的齿形绝大部分是根据理论摆线的原理，经过修正而制作的修正摆线齿形。
擒纵调速器
擒纵调速器是由擒纵机构和振动系统两部分组成，它依靠振动系统的周期性震动，使擒纵机构保持精确和规律性的间歇运动，从而取得调速作用。叉瓦式擒纵机构是应用最广的一种擒纵机构。它由擒纵轮、擒纵叉、双圆盘和限位钉等组成。它的作用是把原动系的能量传递给振动系统，以便维持振动系统作等幅振动，并把振动系统的振动次数传递给指示机构，达到计量时间的目的。
振动系统主要由摆轮、摆轴、游丝、活动外桩环、快慢针等组成。游丝的内外端分别固定在摆轴和摆
夹板上；摆轮受外力偏离其平衡位置开始摆动时，游丝便被扭转而产生位能，称为恢复力矩。擒纵机构完成前述两动作的过程，振动系在游丝位能作用下，进行反方向摆动而完成另半个振动周期，这就是机械钟表在运转时擒纵调速器不断和重复循环工作的原理。

学习笔记-fpga设计电子时钟(12864显示)

fpga设计电子时钟（12864显示）设计心得：1，进行分块设计，类似调用函数，脉冲使能2，充分了解fpga的并行特性（c程序的串行特性，不能并行处理，线性：只有完成了当前任务，才能进行下一个任务）设计问题：1，似乎读有问题，在char_LR=1时，写的数据为汉字（程序中时间没有更改，主要为了调试看波形）实际板子验证时，将LCD_clk模块中的分频调为50到100kHz左右整体架构功能模块液晶初始化时序parameter Idle =8'b0000_0001,Basic_com =8'b0000_0010, //basic instruction:0x30Disp_set =8'b0000_0100, //set show curse blingDDRAM_clear =8'b0000_1000, //colunm address XWait_clear =8'b0001_0000,Point_set =8'b0010_0000,Show_on =8'b0100_0000,Stop=8'b1000_0000;写字符的时序由于字符属于半宽字形，且DDRAM形式下，每行只有8个地址，而字符可以写16个，因此用下面三个来表示写的地址：i nput [1:0] Y, //row 0-3i nput [2:0] X, //clunm 0-7i nput LR, //0/1因此当LR=0时，直接写地址，然后写一个字符编码即可LR=1时，先写地址，读出高位数据，然后写入两个字节（读出的数据，要写的数据）parameter Idle =8'b0000_0001,DDRAM =8'b0000_0010, //drawing modeW_addr =8'b0000_0100, //row address YDummy =8'b0000_1000, // not really readingR_data =8'b0001_0000, //reading high byte dataW0_data =8'b0010_0000,W1_data =8'b0100_0000,Stop =8'b1000_0000;# t1: 0 t2: 2305, T: 10,n_init: 38 # t1: 2305 t2: 2665, T: 10,n_char: 6 # t1: 2665 t2: 3265, T: 10,n_char: 10完成了上述工作，就可以设计一个简单的电子时钟，其要求如下：在屏幕上显示时间00：00：00要动态走（主要就是控制脉冲信号的产生）设计思路：100：00：0023LCD更新数据显示00:00:0100:01:591代码/*sign.v//creat the control signclock h:m:s*/module sign(//module LED(input lcd_clk, //100kHzinput sys_rst,output reg lcd_char_en,output reg lcd_init_en,output reg [7:0]char_data,output reg [2:0]char_X,output reg [1:0]char_Y,output reg char_LR);parameter T_w_char = 5,T_lcd_init = 40;reg [47:0] time_out;/* 1s */reg [16:0] cnt_s;reg [5:0] cnt0_clk;reg [3:0] cnt1_clk;reg [2:0] cnt_char;reg [5:0] sec,min;reg [4:0] hour;reg flag_s,flag_init;always @ (posedge lcd_clk or negedge sys_rst) begin //100kHz if(!sys_rst)begincnt_s <=0;cnt0_clk<=0;cnt1_clk<=0;cnt_char<=0;sec <=0;min <=0;hour <=0;flag_s <=0;flag_init <=1'b1;char_Y <= 2'b10;endelsebeginif(cnt_s == (40-1))begincnt_s <=0;flag_s<=1'b1;data_deal; //taskendelsecnt_s <=cnt_s+1'b1;if(flag_init)begincnt0_clk <= cnt0_clk +1'b1;case(cnt0_clk)1 : begin lcd_init_en <=1'b0; end2 : begin lcd_init_en <=1'b1; end3 : begin lcd_init_en <=1'b1; end4 : begin lcd_init_en <=1'b0; endT_lcd_init: beginflag_init <=0;cnt0_clk <=0;enddefault: lcd_init_en <=0;endcaseendelseif(flag_s)begincnt1_clk <= cnt1_clk +1'b1;case(cnt1_clk)1 : begin lcd_char_en <=1'b0; e nd2 : begin lcd_char_en <=1'b1; e nd3 : begin lcd_char_en <=1'b1; e nd4 : begin lcd_char_en <=1'b0; e ndT_w_char: beginif(cnt_char == 3'b111)begin cnt_char<=0; flag_s <=0; endelsecnt_char <=cnt_char+1'b1;cnt1_clk <=0;enddefault: lcd_char_en <=0;endcasecase(cnt_char)//2 3 4 50 : begin char_X <=3'b000; char_LR <=0; char_data <=time_out[47:40]; end //x0:00:001 : begin char_X <=3'b001; char_LR <=0; char_data <=time_out[39:32]; end //0x:00:002 : begin char_X <=3'b010; char_LR <=0; char_data <=8'h3a; end //: ascii 0583 : begin char_X <=3'b011; char_LR <=0; char_data <=time_out[31:24]; end //00:x0:004 : begin char_X <=3'b100; char_LR <=0; char_data <=time_out[23:16]; end //00:0x:005 : begin char_X <=3'b101; char_LR <=0; char_data <=8'h3a; end //: ascii 0586 : begin char_X <=3'b110; char_LR <=0; char_data <=time_out[15: 8]; end//00:00:x07 : begin char_X <=3'b111; char_LR <=0; char_data <=time_out[7 : 0]; endendcaseendendendtask data_deal;beginif(sec == 59)if(min ==59)if(hour == 23)begin hour<=0;min <=0;sec <=0; endelsebegin hour<=hour + 1'b1; min <=0; sec<=0; endelsebegin min <= min+1'b1; sec <=0; endelsesec <= sec +1'b1;time_out[47:40] <= 8'h30+(hour/10);time_out[39:32] <= 8'h30+(hour%10);time_out[31:24] <= 8'h30+(min /10);time_out[23:16] <= 8'h30+(min %10);time_out[15: 8] <= 8'h30+(sec /10);time_out[ 7: 0] <= 8'h30+(sec %10);endendtaskendmodule2代码module LCD_init(//module LED(input lcd_clk,input sys_clk,input lcd_en, //1 is activedoutput reg LCD_RS,output reg LCD_RW,output reg LCD_EN,inout [7:0] LCD_DATA,output reg ACK);reg flag;reg [7:0] lcd_data;reg [7:0] State;reg link_rs;reg link_data;parameter Idle =8'b0000_0001,Basic_com =8'b0000_0010, //basic instruction:0x30Disp_set =8'b0000_0100, //set show curse blingDDRAM_clear =8'b0000_1000, //colunm address XWait_clear =8'b0001_0000,Point_set =8'b0010_0000,Show_on =8'b0100_0000,Stop =8'b1000_0000;reg [9:0] cnt; //16*2*32=2^10 byte(8bits)/* LCD_RW LCD_DATA*/assign LCD_DATA = link_data ?

摘要：现今，高精度的计时工具大多数都使用了石英体振荡器，于电子钟，石英表，石英钟都采用了石英技术，因此走时精度高，稳定性好，使用方便，不需要经常调校，数字式电子钟用集成电路计时时，译码代替机械式转动，用LCD12864显示器代替数码管显示时间，即减小了计时误差，又不失传统的指针风格。

这种表具有时，分，秒显示时间的功能，还可以进行时和分的校对，灵活性好。

本系统利用单片机实现数字时钟功能的主要内容，其中AT89C52是核心元件同时采用LCD12864显示模拟指针时钟的“时”，“分”，“秒”。

它的计时周期为12小时，显满刻度为“11时59分59秒”，另外具有校时功能。

LCD1286 display the simulation pointer clock
Abstract: today, high precision timing tool most used quartz oscillators, body in electric clock, quartz watch, quartz clocks are used quartz technology, so when the higher accuracy, good stability, easy to use, does not require constant adjustment, digital electric clock time with integrated circuit, decoding instead of mechanical rotation, with LCD12864 display instead of digital pipe display time, which reduced the timing error, and do not break the traditional pointer style. This table is, points, seconds show time function, and can be made, and the points when great flexibility. This system using the single chip microcomputer digital clock function of the main content, which is the core element and the AT89C52 LCD12864 display the simulation of the clock "" pointer," points ", "second". Its timing cycle for 12 hours, show when full scale for "11 59 points 59 seconds, in addition has the reset" function.
Keywords: simulation pointer clock; 12864; AT89C52;
一、12864点阵液晶显示器的原理介绍
通常所说的12864LCD显示块是所说的点阵液晶显示模块，就是由128*64个液晶显示点组成的一个128列*64行的阵列，所以也就叫成了12864。

每个显示点都对应着有一位二进制数，0表示灭，1表示亮。

存储这些点阵信息的RAM 被称为显示数据存储器。

如果要显示某个图形或汉字就是将相应的点阵信息写入到对应的存储单元中。

图形或汉字的点阵信息是由自己设计，这时候问题的关键是显示点在液晶屏上的位置与其在存储器中的地址之间的关系。

显示点在64*64液晶屏上的位置由列号（line,0~63）与行号（line,0~63）确定。

512*8 bits RAM 中某个存储单元的地址由页地址（Xpage,0~7）和列地址（Yaddress,0~63）确定。

每个存储单元存储8个液晶点的显示信息。

由于多数液晶显示模块的驱动电路是由一片行驱动器和两片列驱动器构成，所以12864液晶屏实际上是由左右两块独立的64*64液晶屏拼接而成，每半屏有一个512*8 bits显示数据RAM。

左右半屏驱动电路及存储器分别由片选信号CS1和CS2选择。

如果点亮12864的屏中（20，30）位置上的液晶点，因列地址30小于64，该点在左半屏第29列，所以CS1有效；行地址20除以8取整得2，取余得4，该点在RAM中页地址为2，在字节中的序号为4；所以将二进制数单元中即点亮（20，30）上的液晶点。

这是为了使液晶点位置信息与存储地址的对应关系更直
观关，将64*64液晶屏从上至下8等分为8个显示块，每块包括8行*64列个点阵。

每列中的8行点阵信息构成一个8bits二进制数，存储在一个存储单元中。

（需要注意：二进制的高低有效位顺序与行号对应关系因不同商家而不同）存放一个显示块的RAM区称为存储页。

即64*64液晶屏的点阵信息存储在8个存储页中，每页64个字节，每个字节存储一列(8行)点阵信息。

因此存储单元地址包括列地址（Yaddress,0~63）和页地址（Xpage,0~7）。

据00010000（也可能是00001000，高低顺序取决于制造商）写入Xpage=2，Yaddress=29的存储。

二、点阵LCD的显示原理
在数字电路中，所有的数据都是以0和1保存的，对LCD控制器进行不同的数据操作，可以得到不同的结果。

对于显示英文操作，由于英文字母种类很少，只需要8位（一字节）即可。

而对于中文，常用却有6000以上，于是我们的DOS 前辈想了一个办法，就是将ASCII表的高128个很少用到的数值以两个为一组来表示汉字，即汉字的内码。

而剩下的低128位则留给英文字符使用，即英文的内码。

那么，得到了汉字的内码后，还仅是一组数字，那又如何在屏幕上去显示呢？这就涉及到文字的字模，字模虽然也是一组数字，但它的意义却与数字的意义有了根本的变化，它是用数字的各位信息来记载英文或汉字的形状，如英文的'A'在字模的记载方式如图1所示：
图1 “A”字模图
而中文的“你”在字模中的记载却如图2所示：
图2 “你”字模图
在编写软件代码之前必须要先掌握汉字取模的方法。

要得到上表中的文字，我们可以借助取模软件来完成。

目前点阵LCD的取模软件有很多，我们以本开发板配套的取模软件为例来介绍一下汉字的取模方法。

打开取模软件出现如下显示界面：
在绿色输入区中输入图形，我们以输入一个时钟的表盘为例，了解其取模过程。

在绿色输入区中输入图形后按“生成字模”键后就看到字模已经在显示区显示出来了。

在“字模选项”中选择“C51格式”就可以在“点阵生成区”得到你要的显示代码。

经过以上步骤后一个模拟指针时钟就取模成功了，在程序中只要调用这段代码就可显示出，其它图形也用同样的方法。

取完要显示的全部图形代码后我们就可以编程了。

三、硬件电路设计
1. 系统方框图
本系统主要由单片机、DS18B20、DS1302、键盘、LCD显示模块组成。

系统设计框图如图所示。

2.总体设计思路
本系统采用STC89C52单片机作为控制器，通过输出各种电脉冲信号来驱动控制各部分电路正常工作；采用DS18B20作为温度芯片，实时显示当天的确定温度值；采用DS1302作为时钟芯片，自动对时、分、秒、年、月、日、星期进行计数；采用LCD12864作为显示模块对温度和时间进行显示；再加上按键调时，使时钟走时与标准时间一致。

这样就构成了一个多功能电子万年历。

四、程序流程图
五、测试方案与测试结果
1.测试方案
测量是否断路和短路采用测量电阻来换算；测量输入电阻采用串联电阻分压法；测量实际温度和电源电压采用仪表直接测量。

2.测试仪器
所使用的测试仪器设备如表1所示。

的温度点，记录下标准温度计显示的温度和万年历显示的温度。

六、结论
本设计完成了题目基本部分和发挥部分的所有要求，程序采用模块化设计，硬件电路简单、高效，温度采集、LCD显示模块等各项功能均很好地达到了设计要求。

其中，调时模块是本设计的亮点之一。
