INVENSENSE ICM-20948

[vohra alihussain]

I want to use 9 axis motion sensor and I am planning to use INVENSENSE ICM-20948 for this. I know that all the sensors can interface with I2C protocol but the problem is I want to use in SPI protocol but don't know whether magnetometer  in this chip works on SPI or not? I know that  accelerometer and gyroscope can be interface with SPI protocol.

Hi,

Have you seen these libraries, which are written for the MPU9255 (similar to ICM-20948)?

You will have to ask the chip manufacturer about details on what modes the chip will work in.

Best regards,
Jørgen

thank you Jorgen

i have gone through datasheet of manufacturer, to use the magnetometer i have to use I2c

Hi，I did not find that magnetometer can not work on SPI,Where you found the result,Could you told me?Because I was designing the ICM20948 by SPI now.

If your question is related to the sensor, please direct your question to the manufacturer. If you have a question related to code on nRF for reading the sensor data with SPI, please post a new question where you described your issue and setup.

Better driver here that works both SPI & I2C. https://github.com/IOsonata/IOsonata/blob/master/src/sensors/agm_invn_icm20948.cpp

The ICM-20948 is completely different from the MPU-9250.  MPU-9250 driver cannot be used for the ICM-20948.
