以下为我的代码：
I2C_GenerateSTART(I2C2, ENABLE);
/* Test on I2C2 EV5 and clear it */
while(!I2C_CheckEvent(I2C2, I2C_EVENT_MASTER_MODE_SELECT));
/* Send I2C slave Address for write */
I2C_Send7bitAddress(I2C2, MOTOR_WRITE_ADDRESS7, I2C_Direction_Transmitter);
/* Test on I2C2 EV6 and clear it */
程序一直死在这里，等待不到ACK： while(!I2C_CheckEvent(I2C2, I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED));
I2C_SendData(I2C2,Cmd_Byte);
while(!I2C_CheckEvent(I2C2, I2C_EVENT_MASTER_BYTE_TRANSMITTED));
I2C_GenerateSTOP(I2C2,ENABLE);
