Need guidance with IIS2MDCTR and STM32U385

Hi,

Could you please share example for using IIS2MDCTR via SAI on STM32U385.

Thanks

Hello ​@AG123456789 and welcome to the community;

 

I recommend you to look at DataLogTerminal example. This example shows how to use sensor expansion board to send sensor data from a Nucleo board using UART to a connected PC or Desktop and display it on generic applications like TeraTerm. After connection has been established you can also view data from various on-board inertial sensors as well like Accelerometer, Gyroscope and Magnetometer.

This example has been tested with NUCLEO-U385RG-Q RevC and X-NUCLEO-IKS5A1 boards.

I hope this help you.

Thank you.

IIS2MDCTR provides I2C and SPI interfaces.

SAI on STM32U385 is its Serial Audio Interface - I don’t see that this supports either I2C or SPI ?

 

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
