(24条消息) C51之olde显示屏模块的使用_c51 oled_陈学弟的博客-CSDN博客

函数封装

用到的库函数：

HAL_StatusTypeDef HAL_I2C_Mem_Write ( I2C_HandleTypeDef * hi2c ,

uint16_t DevAddress ,

uint16_t MemAddress ,

uint16_t MemAddSize ,

uint8_t * pData ,

uint16_t Size ,

uint32_t Timeout )

参数一： I2C_HandleTypeDef *hi2c ， I2C 设备句柄

参数二： uint16_t DevAddress ，目标器件的地址，七位地址必须左对齐

参数三： uint16_t MemAddress ，目标器件的目标寄存器地址

参数四： uint16_t MemAddSize ，目标器件内部寄存器地址数据长度

参数五： uint8_t *pData ，待写的数据首地址

参数六： uint16_t Size ，待写的数据长度

参数七： uint32_t Timeout ，超时时间

返回值： HAL_StatusTypeDef ， HAL 状态（ OK ， busy ， ERROR ， TIMEOUT ）

向 OLED 写命令的封装：

void Oled_Write_Cmd(uint8_t dataCmd)

{

HAL_I2C_Mem_Write ( & hi2c1 , 0x78 , 0x00 , I2C_MEMADD_SIZE_8BIT ,

& dataCmd , 1 , 0xff );

}

向OLED写数据的封装：

void Oled_Write_Data ( uint8_t dataData )

{

HAL_I2C_Mem_Write ( & hi2c1 , 0x78 , 0x40 , I2C_MEMADD_SIZE_8BIT ,

& dataData , 1 , 0xff );

}

重做上官一号的IIC实验

接线： SCL -- PB6

SDA -- PB7
