later in the document). To do this, append the following to the state name specified in an

event column:

:counter(<registry key name>)

In the example above, the state cars.mpg is in the “elo:110:180:350:400” event column.

To track the number of times that the user activates this transition, enter

“cars.mpg:counter(TouchToDemoMenu) in place of “cars.mpg”. The value in the registry

corresponding to the TouchToDemoMenu key is incremented when the corresponding

event is triggered.

To display the contents of the registry from a CSV file, use the reserved state name

“DisplayRegistry”. That is, add a row to the table with the word “DisplayRegistry” in the

column to the right of the keyword STATE. The remainder of the row is like any other

row in the table – it contains other states to transition to when events occur. Elsewhere in

the table, add the state DisplayRegistry in the column for the event intended to cause the

registry to be displayed.

When the system transitions to this state, playback from the prior state is stopped and the

contents of the registry are displayed on the monitor attached to the BrightSign.

To display only a subset of the registry, use the following syntax:

DisplayRegistry-<registry section name>

To copy the contents of the registry to a file on a CF card, SD card, or USB mass storage

device, enter the following in the state table:

Execute(CopyRegistry <file-name>)

Examples of <file-name> include:

registry-output.csv

sd:/registry-output.csv

usb1:/registry-output.csv

The contents of the registry are written in a comma separated value format, allowing easy

import into spreadsheet applications.

The entry “Execute(CopyRegistry <file-name>)” should be placed in the CSV file in the

appropriate row and column (appropriate state / event). Unlike other entries in this part of

the state table, this entry only executes the specified command (CopyRegistry) and does

not transition to a new state.

Controlling GPIO Outputs from a CSV File (HD2000 only)

When using CSV files on the HD2000, it is possible to control the GPIO outputs from a

CSV file. GPIO’s can be set by appending a GPIO command to the state specifications in

the second column of CSV files. The GPIO’s are set based on the appended command

when the state is entered.
