Events Mirroring

Fov

Hello)

I have a newbie problem

There is a Virtual Device. I want the following:

PUSH(vdvButton) --> BUTTON_EVENT[vdv] ---> <Do something>

In vdv module I use DO_PUSH()/DO_RELEASE() for buttons and ON/OFF for channels, assuming buttons and channels can have IDs 1-255.

In mainline I write the following:

DEFINE_VARIABLE

INTEGER BtnCodes[255]

DEFINE START
// Filling BtnCodes array...
// for (i=1;i<-255; i++) BtnCodes=i

BUTTON_EVENT[vdv, BtnCodes]
{
PUSH:
{
Send_String 0, "'Button #',ITOA(BUTTON.INPUT.Channel),' PUSH'"
}
RELEASE:
{
Send_String 0, "'Button #',ITOA(BUTTON.INPUT.Channel),' RELEASE'"
}
}

But this Button_Event never activates. I expected DO_PUSH/RELEASE would generate BUTTON_EVENT with same button code as in DO_PUSH/RELEASE.

Thanks in advance.

I"m not sure I'm following your question but it looks like the BtnCodes integer array has no length since you are initializing the array one element at a time. After your FOR loop try a SET_LENGTH_ARRAY(BtnCodes,255) and see if that gets you where you want to go.

No way

DEFINE_START

for (cnt = 1; cnt<=255; cnt++)
{
BtnID[cnt]=cnt
ChlID[cnt]=cnt
}

SET_LENGTH_ARRAY(BtnID, 255)
SET_LENGTH_ARRAY(ChlID, 255)

...


BUTTON_EVENT[vdvSCTPServer, BtnID]
{
PUSH:
{
SEND_STRING 0, "'[!] SCTP to Mainline: Button PUSH: #',ITOA(BUTTON.INPUT.CHANNEL)"
}
RELEASE:
{
SEND_STRING 0, "'[!] SCTP to Mainline: Button RELEASE: #',ITOA(BUTTON.INPUT.CHANNEL)"
}
}

BUTTON_EVENT still never activates...

Joe Hebert

Can you post more complete code on what you are trying to accomplish? Maybe it's just lack of sleep on my part but I don't understand what you're asking. Sorry.

Fov

Well, ok. Some more code

---

A part of vdv Module Code

---

MODULE_NAME='SCTP_Comm'( DEV vdvSCTPServer, DEV dvSCTPServer, INTEGER nSCTPPort)

DATA_EVENT[dvSCTPServer]
{
STRING:
{
// Parsing DATA.TEXT to get Button ID to push/release
DO_PUSH(vdvSCTPServer, Parsed_Button_ID)
...
}
}

---

A part of Mainline Code

---

BUTTON_EVENT[vdvSCTPServer, BtnID]
{
PUSH:
{
SEND_STRING 0, "'[!] SCTP to Mainline: Button PUSH: #',ITOA(BUTTON.INPUT.CHANNEL)"
}
RELEASE:
{
SEND_STRING 0, "'[!] SCTP to Mainline: Button RELEASE: #',ITOA(BUTTON.INPUT.CHANNEL)"
}
}

I call DO_PUSH when i get DATA_EVENT(vdv): STRING. It "pushes" a button on a Virtual Device. I want feedback for this event in mainline

Joe Hebert

What you are trying to do should work. I"m not sure offhand if the RELEASE will trigger after a DO_PUSH but the PUSH should. A few questions:

1) How are the two DEVs defined?

2) Do you know a STRING is coming in at dvSCTPServer? You can verify that by doing a send_string 0 in the STRING handler for dvSCTPServer

3) How are you calculating Parsed_Button_ID? Are you sure it's an integer?

Fov

Should, but it doesn't
Diag says, virtual Button actually pushes so the trouble is in mainline BUTTON_EVENT.

Answers:

1)
DEFINE_DEVICE
vdvSCTPServer = 34999:1:0
dvSCTPServer = 0:2:0

2) Sure thing.

3) Absolutely sure.

I just tried this out

DEFINE_DEVICE
dvDev = 0:12:1;
vdvDev = 33009:1:1;

DEFINE_MODULE 'Module' mdl(vdvDev, dvDev)

DEFINE_EVENT
button_event[vdvDev,1]
{
	push:
	{
		send_string 0,"'push'";
	}
	release:
	{
		send_string 0,"'release'";
	}
}

in the module i have somewhere

do_push(vdvDev,1);

turn messages on and i see the result
(0000132575) push
(0000133072) release

If you are saying that Diag is reporting the button press then there must be a problem with the way you have defined your button_event.


fire up Diag again and check that your variable BtnID has what you are expecting.

Enable Push message display so you can see whats going on.

Joe Hebert

Hmm...I wrote a quick test program and it works fine for me. I get the push and release from the DO_PUSH in a module. I know that doesn't help you any but what you want to do should work.

Fov

Joe:

Can I take a look at your code?)

Filpee:

The problem isn't to write BUTTON_EVENT(dv, StaticID), but BUTTON_EVENT(dv, Array_of_IDs) instead.

Main program code:

DEFINE_DEVICE

dvComm = 5001:1:0
vdvTest = 33001:1:0

DEFINE_START

DEFINE_MODULE 'TestMod' mdlTest(vdvTest, dvComm)

DEFINE_EVENT

BUTTON_EVENT[vdvTest,1] {

   PUSH: {
      SEND_STRING 0, 'Got push in main program'
   }
   
   RELEASE: {
      SEND_STRING 0, 'Got release in main program'   
   }
}

Module code:

MODULE_NAME='TestMod' (DEV vdvTest, DEV dvTest)

DEFINE_EVENT

DATA_EVENT[dvTest] {

   STRING: {
      SEND_STRING 0, 'Got string in module'
      DO_PUSH(vdvTest,1)
   }
}

Output when I use Emulate a Device and send a string to dvComm:

Line      4 :: Got string in module - 04:36:43
Line      5 :: Got push in main program - 04:36:43
Line      6 :: Got release in main program - 04:36:43

Joe:

BUTTON_EVENT with statically specified Button ID works for me, for you and for all.

I virtually 'push/release' buttons on vdv. I assume it can have a maximum of 255 buttons.
When I call DO_PUSH/RELEASE, I specify Button ID. I want only ONE BUTTON_EVENT in mainline that could process a PUSH/RELEASE of ANY of 255 virtual buttons

Joe Hebert

OK, here it is with a button array. Works fine:

Main program:

DEFINE_DEVICE

dvComm = 5001:1:0
vdvTest = 33001:1:0

DEFINE_CONSTANT

INTEGER nSomeButtons[] = {11,12,13,14,15}

DEFINE_START

DEFINE_MODULE 'TestMod' mdlTest(vdvTest, dvComm)

DEFINE_EVENT

BUTTON_EVENT[vdvTest,nSomeButtons] {

   PUSH: {
      SEND_STRING 0, "'Got push for button ',ITOA(nSomeButtons[GET_LAST(nSomeButtons)]),' in main program'"
   }
   
   RELEASE: {
      SEND_STRING 0, "'Got release for button ',ITOA(nSomeButtons[GET_LAST(nSomeButtons)]),' in main program'"
   }
}

Module:

MODULE_NAME='TestMod' (DEV vdvTest, DEV dvTest)

DEFINE_EVENT

DATA_EVENT[dvTest] {

   STRING: {
      SEND_STRING 0, 'Got string in module'
      DO_PUSH(vdvTest,11)
   }
}

Output when using Emulate a Device to send a string to dvComm

Line      1 :: Got string in module - 04:59:13
Line      2 :: Got push for button 11 in main program - 04:59:13
Line      3 :: Got release for button 11 in main program - 04:59:14

Fov

Nice,

INTEGER nSomeButtons[] = {11,12,13,14,15}

But how to do the same thing with { 1, ... , 255 } ?
Sure, I don't want to write scary things like { 1,2,3,4,5,6,7,8,9,10,11,12 ... 100,101,102,103... 255}

When I try to fill array in loop, it doesn't work somehow

I should have caught this before. You need to use REBUILD_EVENT() to rebuild the event table.

Like this:

DEFINE_VARIABLE

INTEGER nSomeButtons[255]

INTEGER x

DEFINE_START

FOR (x=1; x<=255; x++) {
   nSomeButtons[x] = x
}
SET_LENGTH_ARRAY(nSomeButtons,255)
REBUILD_EVENT()

Fov

Yup That works Thanks a lot ^^

Joe Hebert

Sure thing.

As further explanation, the event table is built at compile time before your button array is initialized which is why the events weren't firing. That's why you need to use REBUILD_EVENT() so the event table can get reconstructed.

Also if you want to use more than 255 buttons just use SET_VIRTUAL_CHANNEL() in the ONLINE handler for the virtual device. For example if you want 1000 buttons you can do this:

SET_VIRTUAL_CHANNEL_COUNT(vdvSCTPServer,1000)

Have fun.

Fov

Thanks for all

Dan Colegrove

Almost got it.

You almost got it. You want to use the REBUILD_EVENT() function.

Here is an example from NetLinx Help.

DEFINE_DEVICE

dvTP = 10001:1:0

DEFINE_VARIABLE

INTEGER X // loop counter

INTEGER nBTNS[4000]

DEFINE_START

FOR (X = 1; X <= 4000; X++)
{
nBtns[X] = X
}

// the braces below enclose a variable update and
// rebuild_event statement in a single block

{
SET_LENGTH_ARRAY(nBtns,4000)
REBUILD_EVENT()
}

BUTTON_EVENT[dvTP,nBtns]
{
PUSH:
{
// ...
}
}
// end

Fov

I'm newbie in Netlinx. I didn't know such function exists
