Other Parts Discussed in Thread: BQSTUDIO
Hi,
We implemented in our board a fuel gauge bq27542-G1. The component is not yet calibrated and pins are not accessible to calibrate with the bqStudio tools.
To calibrate it by the soft (via I2C), we are implementing API’s which allows to adjust the voltage, the current and the temperature.
In first step, we read BlockData via 0x40 excommand and then read the BlockDataCheckSum via 0x60 excommand.
The checksum and read BlockData values are not aligned.
Please find below a screenshot that illustrates the results obtained.
Indeed, I have some other questions to ask:
1- Is it fesable to properly calibrate the fuel gauge softwarement with the existing documentation? If yes, is there a detailed document about calibration steps via I2C? (order of command execution, conditions taken into consideration).
2- What are the steps to follow to ensure the proper initialization of the device?
BR,
GO.
