LSM6DSO freeze and doesn't respond

[Aurelien3]

Hello, 

 

I use LSM6DSO with my stm32L476. 
I use I2C 100kz with 10k pull up resistor. The LSM6DSO is next to the STM32. 

I use INT1 with wakeup parameter to indicate the movement and wake the STM32.

I have a problem, sometimes the LSM6DSO freeze. There is no edge to INT1 pin and we cannot communicate throught the I2C bus. So I cannot reset by I2C. 

I don't understand why, it can appears after 1 weeks or 3 months of uses. It depends. 

I have to cut off the power to resolve the issue. 

The LSM6_INT1 pin directly connected to the STM32. 

 

 

Thank you for your time 

Aurelien

Hi @Aurelien3 ,

Can you implement our official drivers and let me know if you still have the issue?

Just to exclude problems related to your code.

Thanks.
