具有HAL库的STM32l1xx I2C

Question

我正在一个项目中，我需要将STM32L152RDT6设置为I2C的从设备，但我无法获得它。 我尝试过，但是失败了：

 HAL_I2C_SlaveRxCpltCallback(&hi2c1);
 I2C_HandleTypeDef hi2c1;

 uint8_t aRxBuffer[1];
 uint8_t aTxBuffer[] = " ****I2C_TwoBoards communication based on Polling****  ****I2C_TwoBoards communication based on Polling****  ****I2C_TwoBoards communication based on Polling**** ";

    if(HAL_I2C_Slave_Receive(&hi2c1, (uint8_t *)aRxBuffer, 1, 10000) != HAL_OK)
        {
          /* Transfer error in reception process */
          Error_Handler();
        }
      else{
          printf("succeed\n");
           printf("I2C data: %d ",aRxBuffer[0]);
      }

    void HAL_I2C_SlaveRxCpltCallback(I2C_HandleTypeDef *I2cHandle)
    {
       /* Turn LED6 on: Transfer in reception process is correct */
        printf("Amazing\n");
    }

我需要一个示例，请使用HAL库将STM32设置为I2C的从设备。

非常感谢您！
