四、API调用

需包含头文件 board_oled.h

Board_initOLED

OLED_writeValue

OLED_writeString

OLED_writeStringValue

OLED_clearLine

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
