bq76920 Evaluation Module User's Guide
The installation comes with 3 sequence files. The
Clear Faults
files contain descriptions for requirements
for a sequence file.
The Set UV Trip...
file shows an example of a simpler format. Sequence files are
installed to: C:\Users\<account-name>\Documents\Texas Instruments\bq76940\sequence. Sequences are
loaded from this location when the program starts. Create new sequences with a text editor and save
them with the .bqseq extension. Up to 8 sequences can be stored, move other sequences to another
directory or change the extension. The sequences
Sequence_Example.bqseq
,
Sequence Clear
Faults.bqseq
, and
UVTrip.bqseq
are required, do not move them from the directory.
Typical uses of a sequence might include:
•
Reading and clearing faults, then enabling CHG and DSG outputs
•
Setting ship mode
•
Setting a balance pattern
•
Any repetitive multiple-register write used in evaluation
While sequences can be executed during logging, the logging is paused while the sequence executes.
Long sequences leave gaps in the log data.

Typical Operation of Software
Typical operation of the software involves the following steps, much like described in
section:
•
Connect the EVM and related equipment
•
Power the EVM
•
Boot the EVM
•
Start the software
•
Read and change registers, as desired
If the board is powered off during the evaluation process:
•
Power the EVM
•
Boot the EVM
•
Select the
Read Device
button
•
Read and change registers, as desired
If the interface board is connected to a system already in operation and the software has not been exited:
•
Select the
Read Device
button
•
Read and change registers, as desired
4.4.8
Operation with Other Interfaces or Hosts
The bq76940/bq76930/bq76920 software does not support other interface boards or adapters other than
the EV2300 and EV2400. The software does not operate in a multi-master environment. If operated with
another host on the line, data collisions can occur. Also be aware that the EV2400 has internal pull-up
resistors to 3.3 V, connecting to some shared busses could damage devices on that bus if the bus voltage
differs.

Battery Management Studio Software
The Battery Management Studio software is used for evaluation of the bq78350 gauge. It is also identified
as bqStudio for a compact name. If an earlier version of the bqStudio software is already installed from
another product evaluation, it should still be installed again to load the configuration files and tools specific
to the current version of the bq78350.
5.1
System Requirements
The bqStudio software requires a Windows 7, or later, operating system. Additional items are required and
are described in the installation windows. The examples in this document are from Windows 7.
