Pavan,
You provided the entire circuit schematic with many op amps in various configurations but without nodal voltages. Also, you do not show the specific OPA320 in gain configuration causing the problem. I can see that you use REF3133 with 1k/1k voltage…
Hi Sravya,
Attached is the C2000 PCB design guide PDF and very good to review even if you are an avid PCB designer.

Hi Cedric,
Nope no firmware is required to establish the connection with emulator. You can once go through: F28335 controlCARD ZJZ Schematic [R2.2].pdf
Also, here are hardware guidelines:

Here is a link to a document for bq20z70 and bq20z90, it has a description of the production flow in section 22. /cfs-file/__key/communityserver-discussions-components-files/196/0714.1072.slua404_5B00_1_5D005F00_application-book-for-the-bq20z70-and-bq20z90…
James,
It takes a few minutes for the voltage measurements to update capacity. You also need to calibrate the pack. I attached the general applications book for gas gauges. You can reference Chapter 22 for a detailed production procedure. They calibrated…
1. Most of the orders do come from pack manufacturers, but there are plenty of end system manufacturers that use these devices as well.
2. Yes, you will need to get access to the cells to use the bq20z45 gauge. You may be able to divide down the full…
Yes, the PRO screen is where the commands can be written and read. Your next step after setting up data flash and calibration is to start the learning cycle process. To do that, you need to enable the Impedance Track algorithm. This turns on the FETs…
