Pololu Wixel - Manual (Page 21)

The text displayed in the Wixel list (e.g. “07-C2-C8-3A”) is the serial number of your Wixel. Each Wixel has a unique
32-bit serial number which was randomly generated and assigned to it when the Wixel was manufactured.
The icon displayed in the Wixel list represents the current state of the Wixel. Each Wixel will be in one of these states:
Wixel Status Icon Description
App Running The app you loaded on the Wixel is now running.
App Stopped The app you loaded on the Wixel is currently stopped; the Wixel is in bootloader mode.
No App There is no app on the Wixel; the Wixel is in bootloader mode.
Reconnecting The Wixel is reconnecting, disconnecting, or in a transitional state.
If you select a Wixel, you can see more information about it in the area below the list. The USB Product ID is the
current product ID presented by the Wixel on its USB interface, as defined in the USB Specification. The Port Name
is the name of the virtual COM port that has been assigned to the Wixel. In Windows, the Port Name is also available
in the Device Manager.
The Stop App button stops the application that is running on the currently-selected Wixel, putting that Wixel into
bootloader mode. The Start App button takes the Wixel out of bootloader mode to run the application that is currently
on it.
App Configuration
On the right side of the window, in the App Configuration box, you can see the name of the currently-open app and
the current settings.
You can open a different app by clicking the “Open…” button. In Windows, you can also open an app simply by
double-clicking on it. The Wixel Configuration Utility can open app files in either the WXL format (documented in
Section 9.d ) or the standard Intel HEX [http://en.wikipedia.org/wiki/Intel_HEX] format.
You can change the current settings by double-clicking on a value and typing a new value in. The parameters that are
available depend on the app that is open; different apps have different parameters available.
Please see the documentation for your specific application for an explanation of what the parameters mean,
and what the valid values are. The Wixel Configuration Utility will not prevent you from entering invalid
or inconsistent values.
Writing to a Wixel
After you have chosen the app and settings you want to use, and selected a Wixel, you can write the app and settings
to the Wixel by clicking the Write to Wixel button. This will erase whatever application was previously on the Wixel
and write the new application to the Wixel. When the write operation is done, the Wixel will be restarted and the
application should start running.
Reading from a Wixel
To read the settings from a Wixel that has been programmed, select the Wixel. If the Auto Read checkbox is checked,
then the Wixel will automatically be read. Uncheck this box if you want to retain current settings when changing
