Part Number:BQ34Z100EVM
Hi,
I've been following the step-by-step design procedure, chapter 8.2.2.1 from the datasheet and always (but once) come to a stop at the calibration. One of the first times it worked, but I don't know what I did different.
I've tried some different options and changed the order, even changed a BQstudio config file I found here on the forum. During the data changes the measured voltage already changes from about 240 mV to 4000+ mv. But it is still about a 1000 mV off.
I've been to default a few times and sometimes come to different problems. But mostly that the data is out of range.
Sometimes BQstudio looks completely different on the top and has a lot more options, the calibrate fault I get is a acknowledge problem from the device, and the image on the side shows "zzz" asleep. Will make a screenshot when it happens again.
The attached documents is my last try. I started from default and wrestled through the datasheet step-by-step. When I started all the external lights on the EVM were on, somewhere on the route they all went off, the voltage is 4312mV, but in reality it is 5220mV.
Thanks in advance,
Karolijn
