一、简介
1.1 硬件规格
SSD1306规格书：
链接：https://pan.baidu.com/s/1BtCtp87fTB7VXBG-20czWQ 提取码：vtqv
OLED尺寸： 0.96寸
OLED像素： 128 * 64
OLED驱动IC： SSD1306
接口类型： 4线SPI、3线SPI、IIC接口，可通过配置模块上的电阻等元件切换
1.2 接口定义
| 引脚 | 功能说明 |
|---|---|
| GND | 电源地 |
| VCC | 电源正 3.3~5V |
| D0 | SPI接口时为SPI时钟线，IIC接口时为IIC时钟线 |
| D1 | SPI接口时为SPI数据线，IIC接口时为IIC数据线 |
| RST | OLED复位，OLED在上电后需做一次复位 |
| DC | SPI接口时SPI数据/命令选择脚，IIC接口时用来设置IIC地址 |
二、OLED控制流程
2.1 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 |
| D0 | IOID_9 |
| RST | IOID_4 |
| DC | IOID_26 |
2.2 总线协议
IO口软件模拟SPI
2.3 软件控制流程
①IO初始化。
②根据时序初始化LCD。
③显示。
三、移植文件

四、API调用
需包含头文件 board_oled.h
Board_initOLED
| 功能 | 初始化OLED引脚 |
|---|---|
| 函数定义 | void Board_initOLED(void) |
| 参数 | 无 |
| 返回 | 无 |
OLED_writeValue
| 功能 | 对OLED写入数值 |
|---|---|
| 函数定义 | void OLED_writeValue(unsigned int value, const unsigned char radix, unsigned char line) |
| 参数1 | value：被显示的数值 |
| 参数2 | radix：8, 10, 16进制 |
| 参数3 | line：数值被显示所在的行数 |
| 返回 | 无 |
OLED_writeString
| 功能 | 对OLED写入字符串 |
|---|---|
| 函数定义 | void OLED_writeString(char *str, unsigned char line) |
| 参数1 | str：被显示的字符串 |
| 参数2 | line：数值被显示所在的行数 |
| 返回 | 无 |
OLED_writeStringValue
| 功能 | 对OLED写入字符串和值 |
|---|---|
| 函数定义 | void OLED_writeStringValue(char *str, unsigned int value, unsigned char format, unsigned char line) |
| 参数1 | str：被显示的字符串 |
| 参数2 | value：被显示的数值 |
| 参数3 | format：8, 10, 16进制 |
| 参数4 | line：数值被显示所在的行数 |
| 返回 | 无 |
OLED_clearLine
| 功能 | 清除所在行 |
|---|---|
| 函数定义 | void OLED_clearLine(unsigned char line) |
| 参数 | 无 |
| 返回 | 无 |
五、使用例子
1）添加头文件（例 multi_role.c 中）
#include "board_oled.h"
2）添加初始化代码（multi_role.c 的 multi_role_init 函数末尾中）
// 初始化OLED屏
Board_initOLED();
3）添加显示内容
OLED_writeString("Leung", OLED_LINE0); // 写字符串
OLED_writeValue(557278427, 10, OLED_LINE1); // 写数据
OLED_writeStringValue("day:", 31, 10, OLED_LINE2);// 写字符串+数据
OLED_clearLine(OLED_LINE3); // 清除该行
