Hi Kenneth,

Thanks for taking a look - I'll hook up an oscilloscope and check the SDA and SCL lines.

Kind regards,

Guy

Hello,

Sorry, dont' know. Have in mind that it may not only be the data on the i2c bus, but also timing requirements involved (e.g. between write and read, and sequence of commands). So possible having a logic analyzer to look at the actual data, timing, sequence and compare with the datasheet may be a good idea.

Searching on google for the ICM20948 I could find some possible relevant discussions and source code that may be helpful. Though I recommend reaching out to the manufacturer directly for guideance and possible their drivers.
