Hi,I'm using STM32G474 to drive my BLDC motor, i want to trig low-side phase current sensing ADC when the lower MOSFET is conducted. But the wired thing is even though CMP2 callback did be called by interrupt, ADC also not triggered (ConvCpltCallback...

Resolved! STM32H503RB I3C dynamic address assignment for sensors

Hi Foued,I'm going to connect 10 BMI323 IMUs to STM32H503RB MCU by I3C bus. BEI323 supports I3C and dynamic addressing and 0x68 static address. Is it possible for I3C bus of STM32 to recognize all IMUs by assign different I3C addresses to make all of...
