前言

基础篇结束，接下来我们来开始进行模块驱动

如果懂把江科大的OLED移植成HAL库，那其实也没什么难

首先配置OLED的引脚

这里我配置PA16和17为推挽输出，PA0和1不要用，因为只有那两个引脚能使用MPU6050

根据配置出来的引脚，我们去宏定义那边弄

OLED.h

#ifndef __OLED_H
#define __OLED_H
#include "ti_msp_dl_config.h"#define OLED_SCL DL_GPIO_PIN_17
#define OLED_SDA DL_GPIO_PIN_16void OLED_Init(void);
void OLED_Clear(void);
void OLED_ShowChar(uint8_t Line, uint8_t Column, char Char);
void OLED_ShowString(uint8_t Line, uint8_t Column, char *String);
void OLED_ShowNum(uint8_t Line, uint8_t Column, uint32_t Number, uint8_t Length);
void OLED_ShowSignedNum(uint8_t Line, uint8_t Column, int32_t Number, uint8_t Length);
void OLED_ShowHexNum(uint8_t Line, uint8_t Column, uint32_t Number, uint8_t Length);
void OLED_ShowBinNum(uint8_t Line, uint8_t Column, uint32_t Number, uint8_t Length);#endif

OLED.c

#include "OLED.h"
#include "OLED_Font.h"static void OLED_W_SCL(uint8_t x)
{if (x){DL_GPIO_setPins(OLED_PORT, OLED_SCL);}else{DL_GPIO_clearPins(OLED_PORT, OLED_SCL);}
}static void OLED_W_SDA(uint8_t x)
{if (x){DL_GPIO_setPins(OLED_PORT, OLED_SDA);}else{DL_GPIO_clearPins(OLED_PORT, OLED_SDA);}
}/*引脚初始化*/
void OLED_I2C_Init(void)
{OLED_W_SCL(1);OLED_W_SDA(1);
}
