HAL库中提供了以下I2C函数:
1. 初始化I2C总线:
```
HAL_StatusTypeDef HAL_I2C_Init(I2C_HandleTypeDef *hi2c);
```
2. 配置I2C从设备:
```
HAL_StatusTypeDef HAL_I2C_Slave_Configuration(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t AddressingMode, uint16_t OwnAddress1, uint16_t OwnAddress2);
```
3. 发送数据:
```
HAL_StatusTypeDef HAL_I2C_Master_Transmit(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t Timeout);
```
4. 接收数据:
```
HAL_StatusTypeDef HAL_I2C_Master_Receive(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t Timeout);
```
5. 发送并接收数据:
```
HAL_StatusTypeDef HAL_I2C_Master_TransmitReceive(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pTxData, uint16_t TxSize, uint8_t *pRxData, uint16_t RxSize, uint32_t Timeout);
```
6. 中断模式发送数据:
```
HAL_StatusTypeDef HAL_I2C_Master_Transmit_IT(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, uint16_t Size);
```
7. 中断模式接收数据:
```
HAL_StatusTypeDef HAL_I2C_Master_Receive_IT(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pData, uint16_t Size);
```
8. 中断模式发送并接收数据:
```
HAL_StatusTypeDef HAL_I2C_Master_TransmitReceive_IT(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint8_t *pTxData, uint16_t TxSize, uint8_t *pRxData, uint16_t RxSize);
```
以上是HAL库中I2C的主要函数,可以根据需求选择使用。
