I have a camera that does a battery athentification before being powered on by the battery. I would like to know how the camera is authentificating the battery and replicate it so I can power the camera with a different (much larger) DC source. I have access to a decent logic analyzer to look at the communication between the battery and the camera but wondering how would I know what the communication protocol will be? I'm not familar with logic analyzers so perhaps I can take a reading and then try to decode my measurement in different protocols until something works. I'd guess I2C or SMBUS but is there a better way then guess and check?
