Can you please make sure that the pull up resistors are connected on the I2C lines?
Which API returns CY_U3P_ERROR_FAILURE error? Is it CyU3PMipicsiInit or sensor configuration?
If it is while configuring the sensor can you please check if the sensor address is set correctly?
Thank you for the response...
> Yes, the pull up resistors have been connected on the I2C lines.
> The CY_U3P_ERROR_FAILURE error is not returned on CyU3PMipicsiInit - it is returned on I2C calls: CyU3PI2cTransmitBytes and CyU3PI2cReceiveBytes.
> Yes, the sensor addresses have also been verified.
