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：
class CN_UTF8:
"""docstring for CN_UTF8"""
#key:values
#key: 使用汉字的UTF-8码
#values: 16*16
# [0] 8*16 上半部分
