4.2.1.2 RUN BUTTON
To restart communication between the software and the evaluation board, click the
Run
button. This button disappears when communication resumes.
To close the program, press the
Close
(
X
) button on the upper right corner of the
window.
4.2.1.3 COM STATUS INDICATOR
The
COM Status
indicator shows the status of communications over the SMBus.
During normal operation, COM Status is green. If SMBus communications fails, COM
Status turns red (or alternates red and green).
4.2.1.4 REGISTER READ DELAY
The
Register Read Delay
sets the GUI control panel update speed. It affects the
speed that the software reads the registers, but will not affect the device’s sampling
time. The default is 25 ms. This number can range from 0 to 5000 ms in increments of
25 ms.
4.2.1.5 SINGLE/CONTINUOUS READ
The panel defaults to continuous register reads (toggle switch in down position, as
shown in
Figure 4-2 ). To stop continuous register reads, check the “Single Read
Enable” box. In order to capture the register values at a given time, click the switch,
which will briefly flip to Single Read.
4.2.1.6 DEFAULT
When this button is pressed, it loads the defaults to all registers of the UCS81003.
4.2.1.7 STEP
When selected,
Step
will go through the Emulation Profiles in sequence, from Legacy 1
through 7, then BC1.2 DCP, and finally Custom. The actual DCE cycle is slightly
different, please see product’s data sheet for more information.
4.2.1.8 DEMO
The
Demo
button enables an automated routine to cycle through a user-defined set of
profiles and selects the highest current profile. This feature emulates an external
controller and is not part of the UCS81003 device.
Note:
Stopping and restarting the GUI does not affect register settings. To restore
default register settings, disconnect power from the board, then reconnect
power.
