Example print "BrightSign Button-LED Test Running" p = CreateObject("roMessagePort") tmr = CreateObject("roMessagePort") gpio = CreateObject("roGpioControlPort") gpio.SetPort(p) event_loop: msg=wait(0, p) if type(msg)"roGpioButton" then event_loop butn = msg.GetInt() if butn > 5 then event_loop gpio.SetOutputState(butn+17,1) print "Button Pressed: ";butn msg = wait (500, tmr) gpio.SetOutputState(butn+17,0) clear_events: msg=p.GetMessage():if type(msg)"rotINT32" then clear_events goto event_loop Classes For each class a brief description is given, a list of interfaces, and the member functions in the interfaces. roList A general purpose doubly link list. It can be used as a container for arbitrary length lists of Roku Objects. Interfaces: • ifList Count() As Integer IsEmpty() As Boolean ResetIndex() As Boolean AddTail(obj As Object) As Void AddHead(obj As Object) As Void FindIndex(name As String) As Boolean RemoveIndex() As Object GetIndex() As Object RemoveTail() As Object RemoveHead() As Object GetTail() As Object GetHead() As Object 8
oMessagePort A message port is the place messages (events) are sent. See the “Event Loops” section for more details. When using Roku BrightScript, you would not call these functions directly. Instead, use the “Wait” BrightScript statement (see the BrightScript documentation). Interfaces: • ifMessagePort GetMessage() As Object WaitMessage(timeout As Integer) As Object PostMessage(msg As Object) As Void 9
