nokia5110_nokia3310中文数据手册

Nokia 3310 LCD显示原创Nokia 3310手机的点阵LCD模块不仅小巧、省电、驱动容易，而且价钱也便宜。

因此，最近网上常见到不少朋友都在用单片机来驱动该模块，制做出很多作品。

在此，我要特别感谢神舟兄，是在他的热情帮助下，我才购得这款3310的液晶显示模块。

如果有朋友需要的话也可以和他联系（神舟emal：conglp@ ）。

实验目标本实验我们就采用Atmega8或者Atmega48来驱动3310的LCD。

在LCD上显示和移动汉字；在LCD的最上一行显示“欢迎光临电子爱好者俱乐部！”，并且让这串汉字在LCD上从左至右不停地移动。

在LCD上显示英文字符串；在LCD的最底一行固定显示“”。

在LCD上显示位图。

在LCD的中间位置显示“AVR”和“实验室”两个位图。

本站商城提供该LCD模块邮购：/shop/index.asp实验器材Atmega8或者Atmega48芯片一只、3.3V稳压二极管一只、3310LCD点阵液晶显示屏。

Atmega8和Atmega48的管脚顺序完全相同，硬件可以直接替用。

实验电路图及工作原理由于3310LCD的工作电压范围是2.7－3.3V，因此实验中使用一个3.3V的稳压二极管D1将5V电源稳压为3.3V左右，为MCU和LCD供电。

MCU和LCD之间使用SPI接口传输数据。

LCD模块的引脚排列：从模块的背面看，管脚排列顺序从左至右分别为1至8脚。

如下图所示：注意：LCD模块的引脚即使用导线直接焊接上，也要用东西将金属引脚压下去，否则还是不能接触到内部电路实验源程序主程序：文件名是3310LCDTest.c#include <iom48v.h>#include <macros.h>#include "lcd.h"#include "bmp.h"/*******************************************/void

NOKIA手机工程模式简介许多朋友都听说过工程模式，但对工程模式究竟如何开启又有哪些作用就不太清楚了，这里我以Nokia 手机工程模式为例给大家介绍一下工程模式的开启和使用技巧。

几乎所有的Nokia手机都有工程模式（经测试，Nokia的5110、5130、6110、6130、6138、6150、3210、8210、8850、6210、3310、8250均具备工程模式），不过它是隐藏在菜单中，需要特殊的方法打开工程模式后你才能看见。

Net Monitor在诺基亚51××/6100中共有88个画面(6100软件版本在V5.0以后则为89个画面)，6150则为89个画面，而8210则有编号为140的画面，实际上有些为空，但比6150多。

前19个画面称为Operator Net Monitor，以系统网络功能为主，后面的则被称为R&D Net Monitor，以手机软硬件的资料为主。

注意:很多朋友都以为工程模式能修改手机功能或增强信号，其实，工程模式只能显示GSM900/1800网络的执行情形或显示手机内某些有用信息作为参考用，不能修改手机功能或增强手机信号。

同时，由于手机本身并非精密的仪器，所有显示的数值仅是近似值，而且因为现在的网络技术不断更新，而手机软件是原先设计的，可能也会有不符的情况发生，因此切记，工程模式仅能作参考使用。

Nokia工程模式的打开Nokia的工程模式在菜单中显示为“Net Monitor”，中文手机也是如此，Net monitor直译就是“网络监视器”，也比较符合实际。

工程模式开启后为常驻，不需再输入任何密码，当然你也可以通过和开启类似的方法再把其关闭。

目前能开启Nokia工程模式的软件很多，如著名的Logo Manager就可以通过数据线或笔记本自带的红外线打开工程模式，功能十分强大。

另外有一个专门用于数据线开启工程模式的小程序94xft.exe，不过只能在DOS下使用。

诺基亚3310液晶是一种OEM产品48X84 pixels matrix LCD controller/driver生产厂家Philips, 型号为：PCD8544可显示84*48点,被评为性价比最好的AVR液晶3310lcd驱动电路:Vdd接3.3V（注意：工作电压是3.3V）或者如图接（1、接100欧姆电阻接5V 2、接二极管再接地）V out接4.7uF电容后接地，电容作用是调对比度GND接地其它的接普通IO口编码显示原理：LCD3310屏幕由84*48个点组成，划分为84列*6行个显示单元，每一个显示单元由1*8个点组成，编程控制显示时按坐标定位，X轴从左到右为0、1、。

83，Y轴从上到下为0、1.。

5，每一个显示单元用一个十六进制0x**控制，0x**转换成二进制后是8个01位，每一个显示单元从上到下为点1到点8，分别对应二进制数的最低到最高位，为1的显示黑点，为0的不显示下面将要讲到的字符显示是用六个连续的显示单元控制显示的，将会显示符号*所以我们可以自由的显示字母、汉字、图片，只要将对应的十六进制控制码写入LCD即可，汉字和图片的控制码可借助于专用的字模生成软件生成。
