How can I detect (from a master device) when a slave Acknowledges its address on the I2C bus?
I can see on my oscilloscope that the slave Acks its address, but I can't figure out how to detect that Ack from the I2C registers on the master.
I'm using a STM32L433 and using LL Driver for I2C.
Kind Regards

I don't know you'll need to review source trees. I'd suppose it progresses beyond the address phase without an error, so look for a state transition or progression.
Review the Reference Manual to understand the mechanics, registers involved and status flags etc.
