Hello, I am wanting to add an "Activity" LED to an I2C bus, but only for slave data, not master data. I think normally I would add a FET to the data line of the I2C bus (SDA line), but this will show activity for the master attempting to communicate with a slave device, as well as activity for a slave device communicating back to the master. Is it possible to achieve this by only lighting up the LED from the slave device communicating back to the master?
Thanks and any help or advice is greatly appreciated!
