Hi,

I understand that you don't want to use the sensor API in your final firmware, but I thought you could try it to see if it had the same issue. However, I'm not sure if there is much point in doing that if it doesn't support the same configuration. I recommend reaching out to the sensor manufacturer to see if they have any suggestions for this.

Best regards,

Vidar

hi,

the "st,lsm6dsl" is not compatible with my project, our project needs to configure lsm6dsl registers like as acc ODR, FIFO ODR, FIFO water mark and so on during runtime. these configurations can't be implemented by "st,lsm6dsl" driver. it is more convenient to use i2c driver.

Hello,

I'm not really familiar with this sensor, but it appears that Zephyr already has driver support for this device. Or is the "st,lsm6dsl" not compatible with your variant? If it is compatible, you could try it with the Generic 3-Axis accelerometer polling

or Accelerometer trigger sample after changing the "compatible" to "st,lsm6dsl";" in your lsm6dsl node to see if you encounter the same problem. This could help us narrow down the problem.

Best regards,

Vidar
