Hello,
I'm using a gas gauge BQ28550-R1 connected to the I2C interface of our i.MX6 application processor. The BQ28550-R1 uses the SMBUS serial data interface which is apparently a subset of I2C protocol. The I2C bus is shared with another peripheral (I2C compatible) and this peripheral can be accessed without any issues.
- First of all, the slave address to identify the BQ28550-R1 on I2C share bus is not specifyied in datasheet. Does it means that this adddress can be changed in the firmware? I found address 0x16 in several threads mail and discussions?
- I don’t know which firmware and configuration has been flashed on my BQ28550-R1, can I read some internal registers with address 0x16 and default firmware?
Many Thanks in advance for your help.
Jean-Marie
