bq76940/bq76930/bq76920 Software
Figure 6. Sequence View
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 & 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 will leave gaps in the log data.
