NOTE: See the “Rollover Regions” section for two additional events you can use with

CSV files.

STATE

After the EVENTS row, there are one or more STATE rows. These begin with the

keyword STATE. The first cell after the STATE keyword is the name of the video or

image file to display. When the “state is entered”, this file starts playing. The remaining

cells describe what state to jump to when the corresponding event happens. For example,

in the above example, the first state is “demo_menu.bmp”. This is the main menu for the

demo, and is displayed when the demo starts. While “in this state” (the demo_menu.bmp

is showing), if the user presses the elo touch screen or clicks the mouse in the right spot

to trigger the “elo:110:180:350:400” event, then the new state “cars.mpg” is jumped to.

If you look at the STATE rows, you will find one that starts with “cars.mpg” (there can

be only one state with a particular file).

To understand this better, look at the actual demo “autoplay.csv” file in Excel while

playing the demo on your BrightSign. As you select options on the BrightSign, see how

the .CSV file is telling the BrightSign what to do. You can then edit the “autoplay.csv”

file in Excel and Save As… a CSV file to create your own applications.

Preloading Images

The autoplay script tries to be smart about preloading still images so that when a user

triggers their display, they pop up immediately. Here are the rules that are used to

preload an image:

1. If a state (row in the table) only has one possible next bmp state, then it is

preloaded.

2. If a state has more than one possible next bmp state, but one of them is the next

row in the state table, then it (next state row’s file) is preloaded. So if you have a

sequence of images that display one after the other, put them in sequential rows in

the state table to trigger preloading. As an example of this, see the bs1.bmp,

bs2.bmp, etc states (rows) in the prior table.

State File (CSV) Examples

The BrightSign Demo described above shows that you can design powerful interactive

signs using easy to understand CSV files. The following examples further illustrate how

easy CSV files are to use.
