欢迎加入讨论群 64770604 一、本次实验所需器材

1、TPYboard V102板  一块

2、DS3231模块   一块

3、NOKIA 5110 LCD 屏 一块

4、杜邦线：若干

===感谢某宝“萝卜城”提供的TPYboard V102豪华版套餐===

二、Nokia 5110 LCD屏使用方法 1、什么是Nokia 5110 LCD?

Nokia 5110 LCD是NOKIA 公司生产的可用于其5110、6150，6100 等系列移动电话的液晶显示模块，国内厂家也生产有类似的兼容产品。该产品除应用于移动电话外，也可广泛应用于各类便携式设备的显示系统。与其它类型的产品相比，该模块具有以下特点：
●84x48 的点阵LCD，可以显示4 行汉字，
●采用串行接口与主处理器进行通信，接口信号线数量大幅度减少，包括电源和地在内的信号线仅有9 条。支持多种串行通信协议（如AVR 单片机的SPI、MCS51 的串口模式０等），传输速率高达4Mbps，可全速写入显示数据，无等待时间。
●可通过导电胶连接模块与印制版
●LCD 控制器／驱动器芯片已绑定到LCD 晶片上，模块的体积很小。
●采用低电压供电，正常显示时的工作电流在200μA 以下，且具有掉电模式。

2、Nokia 5110 LCD 引脚说明

Nokia 5110 LCD共有8个引脚，不同的板子可能标注的英文略有不同，具体含义如下：

标注	含义
GND	接地
BL	背景灯
Vcc	3.3V
CLK	时钟信号
DIN	数据流
DC	当为0时表示命令状态，当为1时表示数据状态
CE	使能端
RST	RESET

3、Tpyboard V102连接5110的方法

这里使用的是SPI连接方法，如果你对什么是SPI连接还不是很清楚，你可以百度一下，这样有利于你从原理上搞明白为什么这么连接。具体针脚对应如下：(由于tpyboard v102有两个spi接口，这里我们选用x1对应接口）

TPYboard	5110LCD	SPI
GND	GND
X4	BL
3.3V	Vcc
X6	CLK	SCK
X8	DIN	MOSI
X3	DC
X2	CE
X1	RST

4、5110 LCD字模的获取

（1）英文及数据的显示

本节提供了font.py文件，已经将英文、数字及符号的字模做好，可以直接调用。具体下载见文章最后的下载地址。

（2）汉字取模

汉字取模需要用到字模提取工具，该工具在文章后面的下载地址中可以下载。这里以“欢”为例具体说明使用方法如下：

第一步，打开工具：

第二步，点击新建图像，宽度与高度均为16，点击确定。如图：

第三步，在文字输入区写入要取模的汉字“欢”，按下ctrl+enter。

第四步，点左边菜单里的取模方式，点c51格式，于是得到：

0x04,0x24,0x44,0x84,0x64,0x9C,0x40,0x30,0x0F,0xC8,0x08,0x08,0x28,0x18,0x00,0x00,
0x10,0x08,0x06,0x01,0x82,0x4C,0x20,0x18,0x06,0x01,0x06,0x18,0x20,0x40,0x80,0x00,

第五步，对应填写到chinese.py文件中（该文件可从文章后面的网址下载），如下：
