MIMXRT685-EVK_How to generate the repeated start via "i3c_master_transfer_t".

[Jin_Tien]

Hi everyone,

I have captured an I3C waveform as below picture:

The byte reading in this waveform as below:

Start, 0x7E (address, Write), [Repeated Start Bit], 0x31, .... , Stop

And I wish to reproduce the below I3C waveform via function "i3c_master_transfer_t". 

The function I wrote as below: 

However, the [Repeated Start Bit] is not appeared in this waveform:

In this case, I have a question wish to have brainstorm with you:

Can I add a [Repeated Start Bit] between "Slave address bit" and "Sub Address bit"?

Hello @Jin_Tien ,

  Thanks for your updated information.

  To your new questions, could you please help to create the new case, then we can spend more time for the testing.

  Normally, Write is used for write the code, Read, just sendout the clock, then the data is from slave side.

So, your read following data, should not from Write master side, should from slave.

  If you think it still from the master, please help to create the new case, and let me know, and also attach your test code.

Best Regards,
