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.

print "BrightSign Button-LED Test Running"

p = CreateObject("roMessagePort")

tmr = CreateObject("roMessagePort")

gpio = CreateObject("roGpioControlPort")

gpio.SetPort(p)

sw = CreateObject("roGpioControlPort") 'switch/led control port

sw.SetPort(p)

event_loop:

msg=wait(0, p)

if type(msg)<>"roGpioButton" then event_loop

butn = msg.GetInt()

if butn > 5 then event_loop

sw.SetOutputState(butn+17,1)

print "Button Pressed: ";butn

msg = wait (500, tmr)

sw.SetOutputState(butn+17,0)

clear_events:

msg=p.GetMessage():if type(msg)<>"rotINT32" then clear_events

goto event_loop
