BQ24745: can a commercial laptop battery communicate to a micro controller via SMBus
thank you Wang, i examined a laptop battery. i connected the "system present" pin to ground. so the power appeared across the + and - terminals. but the clock and data pins does not have any signal. probably i must to prepare clock to the battery. may i think true?
I am not sure your hardware connection. If you don't connect the battery with a communication box (such as: EV2300 or EV2400), where do you probe the clock? Do you have EV2300 or EV2400 connecting to your laptop.
i had connected the probe to the battery while the battery was disconnected form the laptop.
i don't have EV Series equipment.
i have 2 basic questions about smbus ( i2c ) network:
1) does a laptop clock while it is powered from adapter and its battery disconnected? ( or in an i2c network a master must to be connected to a slave then clock is generated. )
2 ) a master is necessary for a smbus ( i2c ) network or a host+slave is sufficient?
