五、基础知识
1、本文使用的是什么LCD？
答：
使用的是opengua设计的OLED。
1）图片
2）购买地址
https://item.taobao.com/item.htm?spm=a1z10.1-c-s.w4004-16963296341.2.5c196d0ci31tGM&id=558148641485
3）基本参数
2、本文控制LCD的流程是如何的？
答：
1）硬件连接
| OLED引脚 | 香瓜CC2640R2F开发板引脚 |
| GND | GND |
| VCC | VCC |
| D0 | IOID_9 |
| D1 | IOID_10 |
| RST | IOID_4 |
| DC | IOID_26 |
3）软件控制流程
①IO初始化。
②根据时序初始化LCD。
③显示。
六、硬件原理
1、开发板对应位置
需将拨码开关的左8、左9、左11、左12，共4个按键上拨。
七、实验步骤
1、编写并添加自定义的LCD驱动
1）写一个LCD驱动GUA_LCD.c（存放在“……\simplelink_cc2640r2_sdk_1_40_00_45\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral\src\app\GUA”路径下）

2、工程中添加驱动文件GUA_LCD.c和GUA_LCD.h
注：拖拽至CCS工程的Application文件夹下
添加文件过程中，选项选择如下
3、应用层调用
1）添加头文件（simple_peripheral.c中）
//GUA
#include "GUA_LCD.h"
//GUA
2）添加初始化代码（simple_peripheral.c的SimpleBLEPeripheral_init函数末尾中）
//GUA
//LCD初始化
GUA_LCD_Init();
//LCD测试
GUA_LCD_WriteString("opengua", GUA_LCD_LINE0); //写字符串
GUA_LCD_WriteString("QQ Group:", GUA_LCD_LINE1); //写字符串
GUA_LCD_WriteValue(557278427, 10, GUA_LCD_LINE2); //写数据
GUA_LCD_WriteStringValue("GUA age:", 27, 10, GUA_LCD_LINE7);//写字符串+数据
GUA_LCD_ClearLine(GUA_LCD_LINE7); //清除该行
//GUA3）修改按键处理函数（替换simple_peripheral.c的GUA_HandleKeys函数）

八、注意事项
暂无
九、实验结果
仿真并全速运行，可以看到上电显示如下：
当按下五个不同按键时，会有对应的按键显示。其中“UP”键按键效果如下：
因此，LCD显示成功。
