Dear TI
I have a circuit board with the BQ34Z110 on board I can communicate with the BQ34 with the EV2300 and the TI software However I need to implement my own communication to the BQ with a host microcontroller and this is where I have difficulties as the Datasheet is not very much clear on this
On page 28 of document SLUSB55A is a description of the I2C but not very helpful unfortunately
Is there any where a short example of using the Standard command set to read the Sate of charge remaining capacity ect. from the device
If I understand the Command Set correctly then the host should send the device address then 2 command bytes and the read back 2 bytes of data as shown on page 28 it is not the case or do the host send address 1 byte then read 1 byte back then again send the second byte of the commend and read then back the second data byte
Please help to clear this confusion which one of the a,b,c or d structures (page 28)should I use for the host to communicate the Standard command set to the BQ34 and read back the Battery data
Thank you very much
