Installing the GUI
GUI Overview
The system consists of these components:
•
Host (PC)
—a Windows PC – used to configure and monitor the UCD9080EVM. The GUI (explained in
the GUI section) runs on the host. For the GUI to execute properly, the host needs to have the
Windows .NET v2.0 Framework installed.
•
USB-to-I
2
C adapter
—UCD9080EVM uses the I
2
C interface for communication with the host. The
TI-supplied USB-to-I
2
C adapter does the appropriate conversion so the host can use the USB interface
for communication.
•
Power source
—UCD9080EVM needs 5-V power source to drive. This power is used by the UCD9080
(by regulating to 3.3 V), LEDs, as well as the onboard rails, if used.
•
External voltage rails
—when configured properly, UCD9080EVM can sequence and monitor external
voltage source as well.
•
UCD9080EVM
—EVM board that houses the UCD9080 and peripheral circuits. The EVM can sequence
and monitor onboard as well as external voltage rails, as previously explained.
The UCD9080EVM comes with a Windows application that can be used to configure and monitor the
EVM. The GUI can be used to configure all available options of the EVM such as sequencing and
shutdown order, over/undervoltage timing, etc. It also can be used to monitor the operation of the
sequencer by reporting current readings of voltage and error conditions on all the rails.
Before running the GUI application, ensure that the target hardware is connected and that the Microsoft
libraries are up-to-date.
1. Remove JP29 and ensure that the EVM is powered on by connecting the power source to the board
and then enabling the power source.
2. Connect the ribbon cable from the USB Interface adapter to the EVM board connector.
3. Connect the PC USB cable to the USB Interface Adapter.
Note:
The UCD9080EVM application GUI is written using Microsoft .NET version 2 software and
therefore requires the .NET Framework installed on the PC to run the application. No other
drivers or libraries are required to run the application.
4. To determine the .NET Framework software version you must use the Windows
Control Panel
and
select
Add/Remove Programs
. The Control Panel lists all the installed PC software and you can
determine if the proper Microsoft .NET Framework version is installed.
Note:
To update your .NET Framework to version 2.0, go this URL:
5. To install the GUI, unzip the zip file that containing the GUI binary onto your PC. You must have at
least version 2.0 of the Microsoft .NET Framework installed on your PC in order to run the GUI.
6. Once you have installed the .NET Framework and the UCD9080EVM GUI, you can launch the
application.
