Command Summary 6

Region File

Touch regions may be defined using a simple text file for speed and greater ease of use. Each line in a

region file describes a single touch. There must be no leading blank spaces, only a single space between

each field, and no trailing spaces. Bitmap buffers specified must be pre-loaded with desired images. An

example of the first row of the calculator demo is shown below.

Figure 5: Region File Example

The file above would define four touch regions. The first has an index of 1 is positioned at coordinates

(24, 77), a width of 100, and a height of 41. When it is pressed the bitmap in bitmap index 1 will be

displayed, and when it is not pressed bitmap 17 will be displayed. Three similar regions follow this one.

1.3 Support Tools

Downloaded from http://www.matrixorbital.ca/software/, the GTT Project support tool provides a

simple graphic interface with the full library of GTT series commands. This program allows users to drag

and drop commands into a list that can be transmitted to the GTT, saved, and even loaded for later use.

Command lists can also be converted into binary files using the save as feature. This will allow easy

creation of an AUTOEXEC, or other script files. Finally, the support tool provides a debug window that

will display the data flow to and from your GTT to ensure your command list executes correctly.

1.4 Firmware Upgrades

After release, Matrix Orbital may publish updates to the GTT code base or functionality that can be easily

applied to the unit in the field. While in mass storage mode, place the latest upgrade.bin file from

http://www.matrixorbital.ca/software/GTT2.0/ into the GTT upgrade folder. Then, cycle power to the

unit, watch the screen for status updates, and wait for the screen to reboot. Finally, replace the GTT in

your application and enjoy the new additions to the display you’ve come to know and love.
