Hi,

Anyone willing to help?

I'm trying to make an AMX TP button ramp an amp channel up whilst it's pressed.

If I send the string once, it increments the volume 1db at a time. So I've tried to create a TO Command to repeat the sending.

DEFINE_CALL 'Surround Amp Up'
{
IF(SURROUND_AMP_UP)

WAIT 2
SEND_STRING dvSURROUND, "$50, $43, $53, $45, $4E, $44, $02, $04, $80, $70, $C7, $38, $47, $48"
}

BUTTON_EVENT[dvTP1,11]
{
PUSH:
{
TO[dvTP1,11]
TO[SURROUND_AMP_UP]}
}

I'm a novice, playing at home, so be nice please

This code has not been tested, but in general this is what I do with Volume Ramping.

DEFINE_VARIABLE
Integer dvTP1_ButtonHold;

Define_Function SurroundAmpUp(Dev Device)
{
	//Should be putting this into a Queue and firing out in a Timeline
	//@ a predetermined interval
	SEND_STRING Device, "$50, $43, $53, $45, $4E, $44, $02, $04, $80, $70, $C7, $38, $47, $48";
}
DEFINE_EVENT
BUTTON_EVENT[dvTP1, 11]
{
	PUSH:
	{
		dvTP1_ButtonHold = False;
	}
	RELEASE:
	{
		if ( !dvTP1_ButtonHold )
		{
			TO[Button.Input];
			SurroundAmpUp(dvSURROUND);
		}
		dvTP1_ButtonHold = False;
	}
	HOLD[2, REPEAT]:
	{
		dvTP1_ButtonHold = True;
		TO[Button.Input];
		SurroundAmpUp(dvSURROUND);
	}	
}

Another method

When needing to ramp volume like this I use timelines.

DEFINE_VARIABLE

LONG lVolumeDelay[]={150}
INTERGER nVolRamping

DEFINE_EVENT

BUTTON_EVENT[vdvTP_Vol,nVolBtn]
{
     PUSH:
     {
          IF(!nVolRamping)
          {
               nVolRamping=1
               // send the ramp volume command
               TIMELINE_CREATE(tlVolRamp,lVolumeDelay,1,TIMELINE_ABSOLUTE,TIMELINE_REPEAT)
          }
     }
     RELEASE:
     {
          nVolRamping=0
          TIMELINE_KILL(tlVolRamp)
     }
}

TIMELINE_EVENT[tlVolRamp]
{             
    // send the ramp volume command
}

               // send the ramp volume command
               TIMELINE_CREATE(tlVolRamp,lVolumeDelay,1,TIMELINE_ABSOLUTE,TIMELINE_REPEAT)
          }
     }
     RELEASE:
     {
          TIMELINE_KILL(tlVolRamp)
     }
}

TIMELINE_EVENT[tlVolRamp]
{             
    if (timeline.repetition < nVolRampingTimeOut)
           // send the ramp volume command
    else
           timeline_kill(tlVolRamp)
}

I made couple small changes. I got rid of the integer variable because it is redundant, and I added a guard against runaway volume if a button release is missed (habit from R4 days).

Not saying it's wring, because it's a perfectly valid approach, but I've personally always felt timelines were overkill. I use the HOLD [REPEAT, n] method. You can adjust the repeat value if the serial port overruns or keeps going too long; if you buffer your commands, you can also clear the queue on a RELEASE. My problem with serial devices has always been, however, that unless there is a built-in ramp command, it's really fussy to get the ramping to go smoothly without overruns.

I am with Dave, try this

BUTTON_EVENT [dvKP,9] // SELECT Volume Up KEYPAD BUTTON (#9)
{
HOLD[2,REPEAT]:
{
IF (nVol_Lvl < 100)
{
PUT YOUR STRING HERE
nVol_Lvl = nVol_Lvl + 1
ON [dvKP,9]
}
}
RELEASE:
{
OFF [dvKP,9]
}
}
