GUI introduction
6.1
GUI features
The
GUI is designed for debugging power supply applications.
It allows:
•
reading instantaneous power metering information and PFC operating modes;
•
reading and modifying STNRG011 NVM parameters defining the supply behavior (gain, fault management,
delays, PFC/LLC parameters, etc.);
•
reading event history data (fault history, stored in optional E²P);
•
programming optional E²P patches;
•
accessing internal firmware variables (patch needed).

STNRG011 GUI startup screen
The GUI is split in the following areas:
1.
Menu Bar
: used to select the operation mode, i.e. to communicate with
E2P directly, NVM programming, etc.
2.
Metering or Event tabs
: displays power metering information or event history
3.
Traces and Status
: internal debug traces and status bar showing the STNRG011 current status
6.3
Connection management
At startup, the GUI detects automatically the COM port to be used (the GUI selects the CP2102-based VCP).
In case of multiple CP2102, you have to manually select the right COM port via the
COM Port
menu.
You can also open or close the COM port via the menu shown below.
