在IT之后无法以流模式返回

嗨，
我正在研究LIS2DH12，配置它时遇到问题。我想使用Stream-to-FIFO模式，我希望INT1在其中一个加速轴高于阈值时触发。我已配置LIS2DH12寄存器来执行此操作。
然后我这样做：
我初始化所有registerI触发interrupti读取FIF中的所有数据FIFO是空的（FIFO_SRC_REG中的0x20）我读取INT1_SRC以清除IA位，并且我读取0x15。此后FIFO仍为空并且LIS2DH12不填充他，你知道为什么FIFO不以流模式返回吗？
ps：INT_1被锁存，但读取INT1_SRC必须清除它。

Hi,
I'm working on the LIS2DH12 and I have issues when I configure it. I want to use the Stream-to-FIFO mode, and I want INT1 to trigger when one of the acceleration axis is above the threshold. I have configured the LIS2DH12 registers to perform this.
Then i do this:

• I initialialize all the register
• I trigger the interrupt
• I read all the data in the FIFO
• When the FIFO is empty (0x20 in FIFO_SRC_REG ) I read the INT1_SRC  in order to clear the IA bit, and I read 0x15.
  

After this the FIFO still empty and the LIS2DH12 doesn't fill him, do you have an idea why the FIFO doesn't return in stream mode?
ps: INT_1 is latched, but reading INT1_SRC must clear it.
