Hi,
I am trying to use BQ27510 chip to control my single cell Li-ion battery. To be honest I am a bit lost now because of what I have read.
1. I have chip connected through I2C to omap and I can communicate with it.
2. I would like to read voltage power consumption etc. from this chip but values I get are wrong. F.e. Voltage (battery actual have 3.6V read is: 0984 or 06d0 and so on.
What I know. There are version G1-G3 of this chip but they are different in firmware, not in working. I haven't modify or calibrate this chip (totally default, as I bought it).
Q1: What should I do to get it working?
Should I 'flash' it before I can use it? I know that there are EVBoards that can do this and firemvare to use it with (BQStudio or BQeasy), but they are interfacing through I2C so I can theoretically program it via my board (I used I2C with success to comunicate with charger(BQ2426x)m magnetometr, and other chips). I read about 66uS delay between 2 commands, but If I read f.e. only Temperature 0x08-0x09 this delay doesn't influance standard 400kHz I2C communication.
If you want me to provide any measures with oscilloscope or schematic write.
