双LIS3DH的INT线保持低电平

嗨，


所以，时间到了，我使用2个LIS3DH加速度计（分配给它们的两个不同的地址），它们都在我的微控制器上使用相同的I2C线和相同的INT线。

这是它的设计方式，现在必须使它们都工作（不是同时）。

我现在看到的问题是，当我将一个加速度计置于掉电模式并配置剩余设备时，在第一个中断序列之后，所有通信似乎都会消失。 INT线保持低电平（配置为低电平有效）并且它已经死了。

我注意到的是，如果我从任何一个设备中删除INT1连接并解决另一个设备，它就能完美运行。从来没有完全插入它们。

对此问题的任何特殊帮助表示赞赏。

Hi,


So time to get right to it, I am using 2 LIS3DH Accelerometers ( Two Different Addresses Assigned to them), they are both using the same I2C lines and the same INT line on my microcontroller.  

That is the way it was designed and now have to make them both work ( NOT at the same time).  

The problem that I see now is that when I put one accelerometer in Power Down Mode, and configure the remaining device, after the first interrupt sequence all communications seems to die down. The INT line remains low ( configured for active low ) and thats it dead.  

What I have noticed is that if I remove the INT1 connection from anyone of the devices and address the other, it works perfectly. Just never when they are completely plugged in.  

Any particular help on the problem is appreciated.
