Interfacing STM32H7A3 with LSM6DSOX IMU via I2C4 using DMA for 6.6 kHz Data Rate

Hello STM32 community,

I am working on a project that involves interfacing the STM32H7A3 microcontroller with the LSM6DSOX IMU via I2C4 using DMA. I need to achieve a data rate of 6.6 kHz from the LSM6DSOX IMU, while minimizing CPU involvement by offloading the task to DMA.

I would appreciate your guidance on configuring the STM32H7A3 I2C4 and DMA for reliable communication with the LSM6DSOX IMU. Specifically, I'm seeking advice on achieving the maximum data rate, DMA setup, and reducing CPU intervention during data transfers.

Any code snippets, configuration examples, or references to relevant documentation would be highly appreciated. I am using the STM32CubeHAL library.

Thank you for your support!

Best regards,

Akhil Chandran
