Hello everyone, I am a beginner in rust and am currently working with the ICM-20948 sensor. I believe I have made all the correct wiring connections and written the code properly since it worked with another ICM-20948 device. However, with this current ICM-20948 sensor, the code isn’t working, and I keep getting an I2C timeout error.
Is there a way to determine where I might be making a mistake? I'm using the Nucleo-64 STM32F091RC board.
Thank you so much for your help!
