Probably too late to help out JoeD7 , but there's an open PR for a bug causing this conversion issue.

Hi there,

I think it's best that you contact the people that wrote the driver over at the Zephyr GitHub repository. The driver is external and is not written by us. The conversion is happening inside the driver. If you want to omit the conversion then you need to modify the driver somehow, which I can't really help you with as we didn't write it in the first place.

Maybe someone else on this forum has experience with this driver or a better suggestion.

regards

Jared

Is there anymore info on this?

I would like a way to get raw data from the memory locations on IMU. I especially want to access the sensortime memory location, and it isn't clear how to change the sensor_channel_get functions to read that. I definately don't want the SOC to convert the data to g or d/s before printing.

I mean I put the serial data above. How could my I2C lines be wrong if im getting useful data? I have checked again, but this is a math issue in the driver. I have used the math from lsm example and it is better. It provides more accurate and consistent data.

Hi,

Have you checked that the connection is correct? If you probe the I2C lines with a logical analyzer, does it corresponds to what is printed out in the log?
