User Guide - Preliminary
For all demonstrations, the following holds true:
i) up to fifteen different sequences may be programmed
Ii) the colors of individual numbered cells may be set in
either of two ways:
•
a left click on a numbered cell will enable the user to
set the colour value for that cell. In general the color
can be set either by adjusting 'slider' controls to
specify
the
individual
component or by selecting a specific colour from a
palette.
The DA9026 device uses 4 bits to store the color values,
and so the range for the 'slider' values are 0x0 – 0xF.
However, with selection of colors from the general
(standard) palette, the full range of 0x00 – 0xFF for each
color is used, but these are automatically converted to the
correct range for use within the software.
A right click will enable to following short cuts to be used:
•
Set Cell to WHITE
•
Set Cell to BLACK
•
Fill ROW to RIGHT
•
Fill COLUMN DOWN
•
Copy current cell
•
Paste saved cell
•
Fill DIAGONAL UP*
•
Fill DIAGONAL DOWN*
* from the current cell up/down, repeating from bottom/top when the

These parameters are controlled using the following section
of the panel, and are loaded directly into the appropriate
register on the DA9026 device.
Duration sets the length of time the particular sequence will
run. Within the DA9026 device, this is multiplied by the
'Switching Time' (see Timing Parameters).
The 'Fade Mode' indicates the fade time when changing to
the selected sequence; the ranges of values is [0, 2, 4, 8,
16, 32, 64, 128] , and again is multiplied by the 'Switching
Time' by the DA9026 device.
Both of these controls have a right button 'hot-key' to aid
completion of the table, the main feature being able to fill to
the end of the table from the current position with the
current value.

Sequence Order Selection

The parameter settings described above are used for
setting values for up to 15 different sequences. The
sequence order selection panel enables the user to choose
the order in which the specified sequences are displayed.
The sequence numbers can be in any order; and they can
be repeated. The only requirement is that the sequence
(whatever it's length) is terminated by a zero. Consequently
a total of 15 sequences may be chosen from those defined
as per the previous section to achieve the desired effect.

(Note: where possible, the software will guide the user in
the termination of the sequence). This section of the panel
is shown in figure 9.
A drop down menu is provided with this section of the panel
to aid the user in setting the values. This can be seen in
figure 10, and the options available are:
