液晶板12232F

12232模块指令【全屏显示】1.SED1520F0A的接口信号SED1520F0A属行列驱动及控制合一的小规模液晶显示驱动芯片，电路简单，经济实用，内含振荡器，只须外接振荡电阻即可工作。

模块工作的稳定性好。

SED1520F0A与微处理器的接口信号如下。

DB0～DB7：数据总线。

A0：数据/指令选择信号。

A0=1表示出现在数据总线上的是数据；A0=0，表示出现在数据总线上的是指令或读出的状态。

RES：接口时序类型选择。

RES=1为M6800时序，其操作信号是E和R/W；RES=0为Intel8080时序，操作信号是RD和WR。

RD（E）：在Intel 8080时序时为读，低电平有效；在M6800时序时为使能信号，是个正脉冲，在下降沿处为写操作，在高电平时为读操作。

WR（R/W）：在Intel 8080时序时为写，低电平有效；在M6800时序时为读、写选择信号，R/W=1为读，R/W=0为写。

SED1520F0A与两种总线的接口信号和时序的详细资料见液晶显示模块使用手册。

2.MG-12232模块的引脚说明MG-12232模块共有18个引脚，各引脚定义如表1所列。

表1 MG-12232模块的引脚定义3.PIC16F877与MG-12232模块的接口电路现以功能强、价格低的PIC16F877为例说明PIC与MG-12232模块的硬件接口电路。

其接口控制时序采用M6800操作时序，这样SED1520F0A引出的控制信号R/W，A0，E1和E2由PIC16F877的I/O端口portb 的4个脚控制。

接口电路如图1所示。

图中利用可调电阻R3实现液晶的背光亮度调节，直接用电阻R2驱动液晶的背光灯。

由于PIC16F877的位操作指令丰富，所以用软件不难模拟出M6800操作时序。

二、接口软件编程1.SED1520F0A指令集SED1520F0A液晶显示驱动器有13条指令。

表2所列的以与M6800系列MPU接口为例（RES=1）而总结出的指令。

多煎煮模式的智能中药煲刘莉;徐金增【摘要】很多人有这样的经历,在煎中药的时候,一不小心就会发生煎糊的现象。

那么这种煎糊的中药还能喝吗？中医专家认为,糊了的中药成分会发生变化,起不到治疗作用不要紧,可能会产生有害物质,危害人体健康,禁止服用。

为了方便病人服用中药药剂,目前已经有一些生产厂家推出了自动中药煲,并在市场上进行销售。

经过调查及实物分析,这些所谓自动中药煲也就只是利用了类似传统电饭锅的原理,将待煎煮中药材的水份煎煮至某一固定程度而已。

它们原理简单,对煎煮对象采用固定的煎煮模式,虽然解决了煎糊的问题,可却不能解决不同类型中药药剂采用不同的煎煮模式,这极大影响了中药的药效。

人们急切需要一种能较好实现中药煎煮自动化、智能化的家用电器。

我们特意设计了一款功能全面的中药煲。

它以能按不同类型的中药药剂采用不同的煎煮模式为特色,兼具防干烧、沸锅,自动保温,药渣分离,蜂鸣提示的功能,是初次煎药用户得心应手的工具。

一、概述12232F是一种内置8192个16*16点汉字库和128个16*8点ASCII字符集图形点阵液晶显示器,它主要由行驱动器/ 列驱动器及128×32全点阵液晶显示器组成。

可完成图形显示,也可以显示7.5×2个(16×16点阵)汉字.与外部CPU接口采用并行或串行方式控制。

主要技术参数和性能:1.电源:VDD:+3.0∽+5.5V。

（电源低于4.0伏LED背光需另外供电）2.显示内容:122(列)×32(行)点。

3.全屏幕点阵。

4.2M ROM(CGROM)总共提供8192个汉字(16×16点阵)。

5.16K ROM（HCGROM）总共提供128个字符（16×8点阵）。

6.2MHZ频率。

7.工作温度: 0℃∽ +55℃ ,存储温度: -20℃∽ +60℃8．在线路板上，有一焊接处，标有J2，共3个焊点。

使用并行方式，连接上2个焊点。

使用串行方式，连接下2个焊点。

二、外形尺寸图图 12. 外形尺寸图三、模块主要硬件构成说明●忙标志:BFBF标志提供内部工作情况.BF=1表示模块在进行内部操作,此时模块不接受外部指令和数据.BF=0时,模块为准备状态,随时可接受外部指令和数据.利用STATUS RD 指令,可以将BF读到DB7总线,从而检验模块之工作状态.●字型产生ROM（CGROM）字型产生ROM（CGROM）提供8192个此触发器是用于模块屏幕显示开和关的控制。

DFF=1为开显示（DISPLAY ON),DDRAM 的内容就显示在屏幕上，DFF=0为关显示（DISPLAY OFF)。

DFF 的状态是指令DISPLAY ON/OFF和RST信号控制的。

●显示数据RAM（DDRAM）模块内部显示数据RAM提供64×2个位元组的空间，最多可控制4行16字（64个字）的中文字型显示(本模块只用到其中的7.5*2个)，当写入显示数据RAM时，可分别显示CGROM与CGRAM的字型；此模块可显示三种字型，分别是瘦长的英数字型(16*8)、CGRAM 字型及CGROM的中文字型，三种字型的选择，由在DDRAM中写入的编码选择，在00~0F的编码中将选择CGRAM的字定义字型，10~7F的编码中将选择瘦长英数字的字型，至于A0以上的编码将自动的结合下一个位元组，组成两个位元组的编码形成中文字型的编码（A140~D75F）。

数字指南针1 功能要求数字指南针要求使用固态磁阻传感器将地磁场的方位角转换成数字量的角度信号，利用单片机处理并显示或通过串行口传送到雷达或电子海图仪等航海设备上，从而实现运动方位角信息的显示。

数字指南针要求分辨率小于1O。

2 方案论证数字指南针又叫电子罗盘，是基于地磁场来定北极的一种仪器。

其测量误差不随时间积累，且体积小，可靠性高，响应速度快，相比传统机械罗盘具有较多的优点。

数字指南针的电路系统主要由地磁检测电路、地磁信号放大电路、磁阻传感器消磁电路、微处理器控制电路、液晶显示电路和接口电路组成。

控制器采用单片机STC12C5410AD，地磁检测采用磁阻传感器HMC1022。

STC12C5410AD单片机是宏晶公司产品，其运算速度为标准单片机的12倍，内带A/D转换器，具有强抗干扰性，低功耗，可在线编程等优点。

HMC1022是二维磁阻传感器电路芯片，其原理是利用电阻桥将磁场强度转换成差动输出电压，该信号电压通过运放放大后，输入到单片机进行A/D转换，最后由单片机进行数据处理并将测量方位角的结果显示在LCD液晶显示器上。

数字指南针设计原理框图如图1所示。

电路由地磁检测电路、地磁信号放大电路、磁阻传感器消磁电路、微处理器控制电路、液晶显示电路和串行接口电路组成。

3.1 地磁检测电路地磁检测电路采用Honeywell公司生产的智能弱磁二轴传感器HMC1022。

其分辨率为85μGs，工作温度为-40～300℃，器件可在5～12V电源范围内工作。

芯片使用16引脚小型SOP封装，最低可检测30μGs的磁场，是一款高可靠性、高灵敏度的磁阻芯片。

双轴磁阻传感器内部具有2个相互垂直安放的磁传感器，当磁阻传感器与航船相对固定并保持水平状态时，利用从2个传感器输出的水平与垂直磁分量大小就可以算出方位角θ（见图3）。
