STM32F103VET6基于STM32CubeMX 配置硬件I2C驱动SH1106 OLED屏幕
-
🔖驱动1.3寸SH1106 OLED屏幕其实和驱动0.96寸ssd1306 OLED屏幕驱动代码差不多,只需要修改几个偏移地址就可以了。
-
🌴对于STM32F103VET6单片机有2个硬件I2C接口,分别是I2C1:PB6、PB7,I2C2:PB10、PB11
-
🔰根据STM32F103VET6已有的外设资源,已经配置2个I2C接口。可以根据需求任意选择。在切换硬件I2C接口时,注意修改对应的oled相关驱动函数。
📑使用硬件I2C关键驱动函数
- 📋主要是下面2个OLED 读写函数。
/**
* @brief OLED写入命令
* @param cmd - 待写入命令
* @note 移植时,请使用自己的底层API实现
*/
static void OLED_Write_Cmd(uint8_t cmd)
uint8_t buf[2];
buf[0] = 0x00; //control byte
buf[1] = cmd;
//使用HAL库的API实现
HAL_I2C_Master_Transmit(&hi2c2, 0x78, buf, 2, 0xFFFF);//切换硬件I2C1:&hi2c1
// HAL_I2C_Mem_Write(&hi2c2, 0x78, uint16_t MemAddress, 7, buf, 2, 0xFFFF);
/**
* @brief OLED写入数据
* @param cmd - 待写入数据
* @note 移植时,请使用自己的底层API实现
*/
static void OLED_Write_Dat(uint8_t dat)
uint8_t buf[2];
buf[0] = 0x40; //control byte
buf[1] = dat;
//使用HAL库的API实现
HAL_I2C_Master_Transmit(&hi2c2, 0x78, buf, 2, 0xFFFF);//切换硬件I2C1:&hi2c1
⛳移植说明
-
🌴如果移植到其他型号单片机上,只需将下面的文件夹拷贝到自己项目下面,然后自己的工程当作添加源文件,以及将头文件路径设置进去。
