Greetings,
Two questions about bq27741-g1 I2C access:
1. Just noticed that the data sheet states a max I2C clock frequency of 400kHz. I checked and the EVM runs at just 100kHz. Is 400 truly doable?
2. The users guide states:
"For read-only standard commands, there is no waiting time required, but the host must not issue all standard commands more than two times per second. Otherwise, the gauge could result in a reset issue due to the expiration of the watchdog timer."
I interpret this to say I cannot do a single register I2C read of the data registers (0x00 through 0x39) at a rate higher than 2Hz. Is this correct?
Can I resolve the 2Hz threshold by issuing a multi-byte read? That is, could I, for example, read the entire standard register data set by issuing a repeated read command of register 0x02 with a length of 0x35? Will the gap at 0x30 cause a problem?
Thanks,
Steve
