Hi,
I use STM32F215XX chip communicate with Bq34z110 chip through i2c.
I follow the step in page 28 of slusb55b.pdf
And I follow ,here is the step.
I get different datas from ' step (A) ' , ' step (B) ' , ' step (C) ' , ' step (D) '
Read the ' strp (B) '. I don't read 96 00.
-> I read ' 4C 00 '
Here is the waveform about i2c communication .
< step ( A ) >
-Full
- front
-back
- Value
< step ( B ) > : Here is a problem.
- Full
- Value
< step ( C ) >
-Full
- front
- back
- Value
< step ( D ) > :
I was writing. But reading events happened.
NACK!!, in the final.

Is there something wrong with my i2c communication ?
' step ( B ) ' .. Is this it?
