STM32H503RB I3C private communication
Hi all, I tried to communicate(private) with my I3C slave device by using STM32H503RB board (as a controller). Here's the code from "Introduction to I3C for STM32 MCUs - Application note Chapter 9.8 Private read" uint8_t aTxBuffer[1] = {0x0F}; u...
STM32H503 I3C, I3C_RSTDAA_THEN_ENTDAA issue
Hi, I am working with STM32H503RB.I'm currently testing the function of "I3C_Controller_ENTDAA_IT" from the example code.Capture1 is the result of "I3C_RSTDAA_THEN_ENTDAA"The expected behavior of Capture1 should be 7E06 then 7E07.Why would 7E02 occur...
