Hi,

Tried the above code with ST25R3911B disco board which has STM32L476RET..

here we are not seeing any ret value..but the sensor is responding with some LED indication..

some configuration issue is stopping the ret values to indicate whether the I2C is working or not..

kindly suggest any changes in the code if any..then same configurations can be applied for STM32F103C6...kindly help us out if you have any suggestion.

thanks and regards

HI,

I also did the print inside HAL_I2C_Master_Transmit and also HAL_I2C_IsDeviceReady()...

looks like the state is not moving to HAL_I2C_STATE_READY state...any issue with the I2C settings..do we need to add any pull up ..kindly let me know.

Hi,

wait for TSflag to be set ..looks like timeout issue..let me know where could be the issue.

 while (hi2c->XferCount > 0U)

  {

   /* Wait until TXIS flag is set */

   if (I2C_WaitOnTXISFlagUntilTimeout(hi2c, Timeout, tickstart) != HAL_OK)

   {

    printf("inside while 1 HAL error = %d ",HAL_ERROR);

    return HAL_ERROR;

   }

Thanks and regards

Hi,

No response from any of ST member here....waiting for all your responses.It will really help us move forward..since AC6 is not supported we need to use cubeID to get the I2C communication done..kindly let us know how to move ahead from here

Thanks
