Does NUCLEO-IKS01A1 support I3C? (with NUCLEO-H503RB)

Hi, 

I'm trying to check I3C protocol with NUCLEO-H503RB and IKS01A1.

I just followed below link for I3C. 

https://wiki.st.com/stm32mcu/wiki/Getting_started_with_I3C

And I can see that the master transmit the data but there is no ACK from the slave.(I've attached the scope shot).

I was trying to buy IKS01A3, but it was out of stock, so I just bought IKS01A1. Because it seems same IC. Is it okay?

I've also tried below example from the github, but result is same. 

https://github.com/STMicroelectronics/STM32CubeH5/tree/main/Projects/NUCLEO-H503RB/Examples/I3C

Please help me to find a way to check I3C.

Thank you for reply. 

I found reason because I set the clock 12500 Khz which is maximum.

After I change it to 3000Khz which is recommended by that link. it works well. 

Thank you anyway.

Hello @LukeJang522 ,

Have you checked the below examples, which may help you?

These examples use X-NUCLEO-IKS4A1A and X-NUCLEO-IKS01A3.

For you information, the X-NUCLEO-IKS01A1 is Not Recommended for New Design as shown in this link.

So, you can use this link to buy X-NUCLEO-IKS01A3.
