7.2
Setup Tab
On the
Setup
tab, set the number of cells in the module, which cell and aux channels are monitored,
whether internal chip temperatures are monitored, and the bq76PL455EVM address. The
Board Address
drop-down menu is populated with the addresses of all bq76PL455EVMs discovered during the GUI start-
up.
If there was a problem with auto-addressing during GUI power up and not all connected bq76PL455EVMs
were recognized, reinitiate the search process by clicking the
Do Auto Addressing
button once the
connection problem has been rectified.
NOTE:
Failure to select at least one channel before starting polling results in a GUI error message.
Save the bq76PL455A-Q1 RAM set up data using the
Save Settings to File
button which saves the data to
a file on the PC. These data can later be restored to a bq76PL455EVM using the
Load Settings from File
button.
The
Show Registers
button produces a view, as shown in
, of the user-configurable registers
which the GUI is writing to control bq76PL455A-Q1 operation. In the Registers view, values are observed
and changed in the registers of the bq76PL455A-Q1. These registers are described in detail in the
bq76PL455A-Q1 data sheet (
). Register values are read and written from this
Register View
window, however, values are only written to RAM and cannot be saved to EEPROM using the
bq76PL455EVM GUI. If power is removed from the bq76PL455EVM(s), any changes are lost. For this
purpose, any changes may be saved to and restored from a file using the
Export
and
Import
buttons.
When importing from a file, values are written to all registers as part of the import process. Some
additional detail regarding the control buttons on this window is provided in the Register View Window
section of this document.
NOTE:
Since changes are made using check boxes and radio buttons in the primary GUI window,
registers shown in
Register View
can change while the
Register View
window is open. If
making changes in the GUI while the
Register View
is open, click Read All upon returning to
the
Register View
window.
