Evaluation Software Details
ALERT
A condition has been sensed that is causing the ALERT hardware pin to be asserted. This
is also indicated by the ALERT bit being set (red) in the [DEVICE] STATUS register. The
source of the ALERT condition is indicated in the ALERT register just below the STATUS
register.
FAULT
Similar to the ALERT indicator, this LED indicates the FAULT bit, and FAULT hardware
pin are asserted. The source is indicated in the FAULT register, just below the ALERT
register.
LAST CRC
The last CRC received by the GUI was incorrect for the contents of the packet. This
usually indicates a communications error caused by improper connection, excessive
cabling, etc. The cause of the communications error should be corrected before
continuing.
LOG
Green if a log file is being written to. Logging is useful to capture information about cell or
interface behavior over long periods of time
STACK
At least one device was found during auto-addressing or rebuild addresses. This indicates
that the bottom device in the stack was found, is powered, not in POR, and the ribbon
cable from the Aardvark to the EVM is connected correctly. This verifies the cabling and
connection all the way to the IC.
INTERFACE
The Aardvark USB-SPI interface adapter was successfully found and communicated with.
This verifies the cabling and driver to the adapter.
5.1.5
Global Registers
DEVICE
The Address of the device currently being communicated with. Change to access
different devices in the stack.
“
BROADCAST
”
mode also available to send a single
command to all devices in the stack. (In BROADCAST mode, no data is shown
–
the
interface can only display data from one device at a time.
STACK HT.
The number of devices found during the last AUTO-ADDRESS or
REBUILD-ADDRESS cycle.
POLL
Check or un-check this box to turn polling on or off. Note that many menu items are
unavailable during polling
–
turn polling off to access them.
RATE
This list box allows choosing a polling rate between 100ms and 60s. The LED
illuminates green each time the GUI polls the device stack. Useful as a heartbeat
indicator when polling or logging is active. A setting
“
Fast
”
is also available. In this
position, the WinGUI will poll as fast as possible, with only Windows OS slowing it
down. On most systems, this results in a poll every 10-20ms, but your results may vary
depending on the speed of your CPU and other tasks that are running.
LOG STACK
Enables or disables data logging. Logging is to a file in comma-separated-values (.csv)
format. Set up logging in the LOG | SETUP menu. Logging may also be started /
stopped under the LOG menu. Data is captured each poll, set by the polling interval in
TOOLS | INTERFACE.
VIEW PLOT
Check this box to view a dynamic plot of data collected during polling. See
for further information on configuring the plotter.
