i2c问题

louis102

我用战舰放上mpu6050，模拟运行是总是卡在这一句上，求解释，我用的配置如下；
while(!I2C_CheckEvent(I2C1,I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED));


GPIO_InitTypeDef GPIO_InitStructure;
        I2C_InitTypeDef  I2C_InitStructure;
       
        RCC_APB2PeriphClockCmd(        RCC_APB2Periph_GPIOB, ENABLE );        //ê1ÄüGPIOBê±Öó
          
        GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6|GPIO_Pin_7;
        GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_OD ;   //íÆíìêä3ö
        GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
        GPIO_Init(GPIOB, &GPIO_InitStructure);

       
        I2C_InitStructure.I2C_Mode = I2C_Mode_I2C;
  I2C_InitStructure.I2C_DutyCycle = I2C_DutyCycle_2;
  I2C_InitStructure.I2C_OwnAddress1 = I2C1_MPU6050;
  I2C_InitStructure.I2C_Ack = I2C_Ack_Enable;
  I2C_InitStructure.I2C_AcknowledgedAddress = I2C_AcknowledgedAddress_7bit;
  I2C_InitStructure.I2C_ClockSpeed = I2C_Speed;

  /* ê1Äü I2C1 */
  I2C_Cmd(I2C1, ENABLE);

  /* I2C1 3õê¼»ˉ */
  I2C_Init(I2C1, &I2C_InitStructure);

        /*ÔêDí1×Ö½ú1ó|′eÄ￡ê½*/
        I2C_AcknowledgeConfig(I2C1, ENABLE);
