How to interface X-Nucleo-IKS02A1 with STM32L496 Disco board using LL Libraries? Tried to interface using I2C Channel using LL Libraries , but was not able to read the registers of IKS02A1.

 Hello @GKulk.1​ and welcome to the Community :grinning_face:

You can review the I2C examples available under STM32CubeL4 MCU package:

STM32Cube\Repository\STM32Cube_FW_L4_V1.17.2\Projects\NUCLEO-L496ZG\Examples_LL\I2C

The examples run on STM32L496 NUCLEO devices.

Tried to use I2C as per the examples , But when I try to read WHO AM I Register , I am not getting any data from MEMS Board

Hello @GKulk.1​,

I recommend you follow this flow:

• The related GPIO clock base is enabled
• The related GPIO pins are configured for I2C
• The I2C peripheral clock enabled
• The I2C is configured
• The I2C is initialized
• Generate a Start Condition
• Transmit sensor's write address to send register address
• Send the register address
• Generate a Start condition again
• send the Sensor's read address
• define the read data to a variable
• generate a Stop condition and send NACK to stop the receiving

Hope my answer helped you!
