Using the ICM456868 sensor with the ESP32S3 microcontroller

[brightproject]

For some reason, I couldn't find support for the ICM45686 sensor in this repository, but I did find it in another repository:

https://github.com/SlimeVR/SlimeVR-Tracker-nRF/blob/main/src/sensor/imu/ICM45686.c

Is this because the ICM45686 sensor doesn't work with the ESP32S3 over the I2C bus, or is there some other issue?

Could this be related to this issue?

SlimeVR/SlimeVR-Tracker-nRF#121

I couldn't connect to the ICM45686 sensor via the I2C bus. I was only able to connect via the SPI library:

tdk-invn-oss/motion.arduino.ICM45686#5

I use this board:

Please tell me how to connect to the magnetometer sensor, which is connected via I2C to the ICM45686 sensor MAS_DA and MAS_CLK contacts.

This library contains the following code:

https://github.com/SlimeVR/SlimeVR-Tracker-nRF/blob/712b3c311c0d20812a3f3847ae7bd99446e4f86c/src/sensor/imu/ICM45686.c#L430

But as far as I understood from the document:

https://invensense.tdk.com/wp-content/uploads/2024/07/AN-000478_ICM-45605-ICM-45686-User-Guide.pdf

This mode is only possible when the sensor is connected via I2C and transmits data from a magnetometer, also connected via I2C.

My ICM45686 sensor is connected via SPI, and I still can't find a way or code to extract data from the magnetometer🙂
