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
