Initial screen
You will now want to create a new project to match the fitted display. We’ll call it „memory“.
Press the „New Project“ icon
and enter „memory“ into the popup box. Enter „32“ for the number of outputs, as the
display has 32 connections, even though 2 of them are not used. The number of outputs tells the software what is the
maximum output used.
4.3
Top Plane Connection
Next, enter the output number for the top plane connection into the box at the bottom of the screen. In our example case
this is easy, the information tells us that it is the rightmost connection, which is attached to pin 32. This is output segment
31 in the software.
Watch out for this- pins of connectors are always numbered from 1, but outputs from many chips
including this one, number from 0
. Enter 31 into the box.
What happens if you don’t know the pin number of the top plane connection? It will usually be the last used pin on the left
or right of the display, there may be dummy connections outside. The top plane connection is visible on the right or left of
the display by a large rectangular „blob“ , so the position of this will tell you which end of the connector is used for the top
plane.
4.4
Load Image of Display
Next we need to load in a bitmap image of the display to be used.
With any luck, you have a CAD database with a clean artwork for the display. You can export a bitmap from this in
Windows .bmp format. Size and bit depth is irrelevant.
If not, the information may be present in a Adobe Acrobat .pdf document as in Figure 17 of this document. You can
select an appropriate area, copy it, and paste into Windows Paint program or any other graphical editor. Some
retouching can be carried out to remove arrows, text etc if you wish.
Save this file into the newly created directory
