你现在是一个C语言编程专家我有一段c语言代码 请帮我补充void I2CTransfer函数 利用HAL库读写时序void I2CTransferuint16_t deviceAddr uint8_t cmdArray uint8_t dataArray uint16_t cmdLen uint16_t dataLen uint16_t flagifflag==I2C_FLAG_WRITE_REA

以下是补充完整的void I2CTransfer函数的代码：

void I2CTransfer(uint16_t deviceAddr, uint8_t cmdArray[], uint8_t dataArray[], uint16_t cmdLen, uint16_t dataLen, uint16_t flag) { if(flag == I2C_FLAG_WRITE_READ) { HAL_I2C_Master_Transmit(&hi2c1, deviceAddr, cmdArray, cmdLen, HAL_MAX_DELAY); HAL_I2C_Master_Receive(&hi2c1, deviceAddr, dataArray, dataLen, HAL_MAX_DELAY); } else if (flag == I2C_FLAG_WRITE_WRITE) { HAL_I2C_Master_Transmit(&hi2c1, deviceAddr, cmdArray, cmdLen, HAL_MAX_DELAY); HAL_I2C_Master_Transmit(&hi2c1, deviceAddr, dataArray, dataLen, HAL_MAX_DELAY); } }

请根据您的实际情况将代码中的"hi2c1"替换为您使用的具体I2C外设句柄。同时，需要确保您的工程中已经引入了HAL库的头文件和函数
