My goal is to use the BQ27421 and BQStudio to characterize several batteries and create a "golden image" to eventually program the chip in our design.
BQStudio has a lot of capability but apparently no central document to describe its use.
I completed the Parameter Q&A and intended to start the learning function manually. Following are questions I have regarding this process and BQStudio use:
1) A support member sent me a powerpoint presentation on a "deepdive" on BQStudio. It showed a window in Windows/Settings/Registers that allowed you to set Conditions to Start Charge (or Discharge). I don't see these options in my setup.
2) This window would activate the "EV2300 I2CSDA/HDQ line HIGH (and I2C Vout = LOW)" upon set check conditions. But what is I2CSDA/HDQ? The HDQ port only has VCC/HDQ/VOUT/GND pins.
3) After completion of a manual discharge, the software goes into Relax state. The only way I found to get out of it was to pull the USB cable to the pc. Then it says I can go into Charge phase. Is there a better way?
4) Upon then starting charge phase, the Data Graph shows the battery voltage rising but the I had selected Average Current and State of Charge and they are bogus (-11666 and 0%). Why?
More to come I'm sure....
