Registry (HD2000 only)

The BrightSign HD2000 has an I2C EEPROM with 2K bytes of memory that supports

the storage of persistent settings. The BrightSign software registry object is how

BrightScript reads and writes data to this eeprom. The purpose of the registry is to enable

customers to persist usage statistics and other small amounts of information that may

change regularly

Individual items are stored in the registry through the use of registry keys and values. For

example, there might be a registry key named “NumberOfButtonPresses”; the

corresponding registry value would be used to count the number of times a button is

pressed. Registry data can be organized into different registry sections if desired.

CSV files support writing to the registry, deleting from the registry, and displaying the

contents of the registry – see the Using Excel to Create Interactive Signs section earlier in

the document. The contents of the registry can also be displayed from a playlist – see the

Playlist Commands section earlier in the document. In addition, the registry can be

accessed by a custom script using the roRegistry object (see the BrightSign Object

Reference Manual for additional information).

The number of registry keys and values that can be used is dependent on a number of

factors, including the number of sections, the number of keys/values per section, and the

size of the keys and values. In typical usage, there’s room in the registry for about 50

keys.

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.

Here is an example script that will flash an LED for half a second each time a button is

pressed on the BrightSign button/led board.
