Intelligent Building Series C-Touch Programming Reference

The C-Touch software offers the options of password protected screens and

this is a particularly useful feature for time setting pages and other utilities. If the

time on the unit can be changed by anyone then the schedules programmed

into the unit cannot work as designed.

10.5 Memory Management

The C-Touch Configuration Software generates a file which is downloaded to a

C-Touch unit. The C-Touch units have limited amounts of memory, so the size

of the configuration file that can be downloaded is constrained to within those

limits.

The amount of memory used, and where it is being used, can be displayed in a

pie chart displayed within a dialogue box by selecting Options | Show

Resources. The memory useage is broken down into the following categories:

• Program – this can not be controlled by the user

• Bitmaps – this is the memory used by image components

• Fonts – this is the memory used by the fonts

• Components – this is the memory used by the other components

• Other – this is the memory used by scenes, schedules and other items

• Spare – this is the amount of memory left

A more efficient project can be designed by careful study of the areas of

greatest memory use and subsequent redesign following the hints below.

Note that the information displayed here assumes that Optimisation is set to

OFF. The use of Transfer | Optimise Download File menu item may result in

a considerably smaller project. The exact amount of memory used is displayed

with the Transfer | Prepare Download File menu selection. A file

(resources.txt) is created in the project directory which has further details of the

memory usage.

In order to minimise the size of the download file, these hints should be kept in

mind:

• The number and size of bitmaps should be minimised. (A full-screen bitmap

will use 10k Bytes of C-Touch memory)

• The size of Buttons should be minimised

• The number of fonts used should be minimised (only the fonts for clocks,

percentage indicators and monitors are downloaded)

• The appearance of buttons that do the same thing (eg sliders or a “back”

button) should be identical. Identical buttons are only saved once (if

optimisation is on). Anything which can’t be seen (eg. the group address or

page link details) will not affect memory use.

• Have Optimisation switched on.
