roTouchScreen object. To create an object in a script, the CreateObject() function is

used.

Refer to the following two manuals when writing scripts:

• BrightSign HD600 BrightScript Reference -- this describes the actual scripting

language

• BrightSign HD600 Object Reference -- this describes the Roku Objects, such as

“roVideoPlayer”

Examples

A good way to learn BrightScript is to look at or modify existing scripts. You can find

links to example scripts at www.rokulabs.com/brightsign. The BrightSign Demo

“autorun.bas” is an example of a more sophisticated script.

You can also test BrightScript commands using the shell. Here is an example:

Welcome to the Roku Shell version 1.1.28 Release

Type '?' for help or 'help <command>' for help on <command>.

Roku> script

BrightScript Micro Debugger.

Enter any BrightScript statement, debug commands, or HELP.

BrightScript> print "hello"

hello

BrightScript> ? "hello"

hello

BrightScript> ?5+6

BrightScript> ?type(5)

rotINT32

BrightScript> if 1=1 then print"1 does equal 1!" else print "strange!"

1 does equal 1!

BrightScript> ?right("abcdef",3)

def

BrightScript> exit

Roku>

GPIO Control Port

The BrightSign has a DB25 General Purpose Input Output (GPIO) Port. This port has

12 inputs that can be directly connected to buttons or switches, and 6 outputs that can

directly drive LEDs. To use this port you must create a simple but custom cable that

connects a DB25 connector to your buttons or LEDs. See the BrightSign Hardware

Manual for more information and example circuits. Roku has a test button/LED board

that you can purchase to evaluate the GPIO port and test your scripts that read the buttons

or set the LEDs.
