CC2640R2F学习笔记（2）——OLED屏使用

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

链接：https://pan.baidu.com/s/1FT7PMZoV8jUgoB6WUEkAEw 提取码：wifz
将 board_oled.c 和 board_oled.h 两个文件拖拽至CCS工程的Application文件夹下


添加文件过程中，选项选择如下

3.1 board_oled.c

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
