Part Number: BQ34110
I am playing with the spreadsheet privided by Matt Sunna in another topic (
).
It is not entirely clear to me how to use the spreadsheet. For instance, on the Application Settings sheet, the values are per cell? How do I tell the gauge my pack has 10 (NiMH) cells?
BTW, is there a new version of this spreadsheet?
As a first try I set the values on the App Settings sheet assuming per cell and created the csv file for bqStudio. That leads me to another question.
I am using the BQ34110 EVM with EV2400. I connected the pack to BAT+/BAT-. BqStudio recognized the gauge. I set jumpers on J2 to >5V. I loaded the aforementioned file into bqSudio and wrote to the data file. But when I read it back, it seems the defaults are returned.
The values displayed on the registers windows do not make much sense either. It shows 0V for the output voltage; I would expect something different from zero but maybe it is related to the issue above. I know something is working because the temperature readings change if I head the onboard thermistor.
I will make some modifications to the EVK (thermistor in the pack, correct the resistor value for the voltage divider) but I would like to make sure I works before that. So, what am I doing wrong?
