Here is an example of a script for the HD410, HD810, or HD1010 that flashes an LED for half a

second each time the user presses a button on the BrightSign button/LED board.

print "BrightSign Button-LED Test Running"

p = CreateObject("roMessagePort")

tmr = CreateObject("roMessagePort")

gpio = CreateObject("roGpioControlPort")

gpio.SetPort(p)

gpio.EnableInput(0)

gpio.EnableInput(1)

gpio.EnableInput(2)

gpio.EnableInput(3)

gpio.EnableOutput(4)

gpio.EnableOutput(5)

gpio.EnableOutput(6)

gpio.EnableOutput(7)

event_loop:

msg=wait(0, p)

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

butn = msg.GetInt()

if butn > 3 then event_loop

gpio.SetOutputState(butn+4,1)

print "Button Pressed: ";butn

msg = wait (500, tmr)

gpio.SetOutputState(butn+4,0)

goto event_loop

1 2 ... 67 68 69 70 71 72 73 74 75 76 77 ... 117 118
