Interface Description
The interface comprises three tabbed panels, DA852X, Image, Parameter Control Panel and some common controls
Device Type, Top Plane Connection(s), Field Connection(s), Status Message, and USB indicator.
The interface has file menu items, toolbar icons and keyboard shortcuts for many of the common functions.
Hovering the mouse over controls on the selected panel produces floating “tooltip” text with helpful descriptions of the
controls.

Common Controls
3.2.1
Device Type
This pulldown menu selects a current Project, or allows the creation of a new User Project. We have pre-defined the first
4 and included data appropriate to those device sizes.
The user will normally select “Add Item”, (or alternatively select “New Project” on the File Menu, or “Start a New Project”
on the toolbar ), provide a meaningful project name, and provide the number of output segments in use for that project.
This number can be more (implying a cascade connection) or less that the outputs available on the chip.
A subdirectory under the Data directory is created to hold all the information relevant to this project.
Once a project has been created, it is added to the pulldown menu, and will be reloaded whenever the software is
started.
3.2.2
Top Plane Connection(s)
The user must manually enter the output connected to the top plane connection. Usually this is easily available from the
documentation provided with the display panel and by inspection of the display panel to PCB interface. If not, it can be
deduced, see Tutorial.
Where the physical display has multiple connection tabs, it is possible that each tab has a connection to the top plane
and field (background). If each tab were connected to an Evaluation board, two outputs with opposite phase could be
shorted out. Therefore the software allows multiple top planes to be entered, e.g. “63,127,191”. All these outputs will then
switch in synchronism.
3.2.3
Field Connection(s)
Entering information here is optional, but if multiple top plane connections above are being used, this allows mutiple field
connection to be entered also. The connections entered will switch together always.
3.2.4
Status Message
This message box will display the current mode of the software. This is especially useful to communicate Map entry and
zoom modes.
3.2.5
USB OK? Indicator
A green light here shows that the USB interface is functioning correctly.
If offline mode is in use (offline=1 in [Setup] section of DA852X.ini) then the system will temporarily go online and operate
the hardware if available. The offline mode is not cancelled, however, so a restart of the software will return to offline
mode.
3.3
DA852X Panel
This is the simplest interface to the attached panel, showing the current
state
of the segments. The number of segments
shown reflects the size of the device selected. For large numbers of segments, scroll bars appear to allow access to the
higher numbers.
