controlling winamp volume

**wilgartw** · 07-07-2009, 03:46 PM

in order to press up volume in winamp i need to detect when my potentiometer ouputs say an extra 0.1v.

each time i increase the volts by 0.1v i want to press up arrow
each time i decrease the volts by 0.1v i want to press down arrow

**wilgartw** · 07-07-2009, 03:49 PM

it was something like this:
#ENABLEHIGHSWITCH#true
#ENABLELOWSWITCH#true
#LOWKEYSEQUENCE#DOWN
#HIGHKEYSEQUENCE#UP
#LOWMAINWINDOWTITLE#winamp
#HIGHMAINWINDOWTITLE#winamp
#HIGHTHRESHHOLD#d0.06
#LOWTHRESHHOLD#d-0.06

any ideas / guidance?

hello,

has any one got any ideas on how to control winamp's volume using a potentiometer?

i cannot work out how to do the logic that if the voltage from the potentiometre increases by 0.06V it triggers the sending of the up arrow key to winamp.

sorry I have been crazy busy...

I'll whip some code up

thank you, sorry didn't mean to be pushy, it's just i have the unit out of the van to do this so i am keen to get it all working and back in again.

Ok, first here is the code I based it off of. This is from the source code to Version 2 software:

Code:

...
                    else if (AIDynamicButtonList[i].TypeString.Equals("POTENTIOMETER"))
                    {
                        double vtminus1 = AIDynamicButtonList[i].PreviousRawValue;
                        double vtnow = AIDynamicButtonList[i].CurrentRawValue;
                        bool goingup = true;
                        double diff = vtnow - vtminus1;
                        if (diff < 0)
                        {
                            goingup = false;
                        }
                        else if (diff > 0)
                        {
                            goingup = true;
                        }
                        if (goingup && diff > AIDynamicButtonList[i].HighSwitchValue)
                        {
                            //There is less voltage, and the change is greater than the histeresis, so do the up command
                            if (AIDynamicButtonList[i].LOW_KeySequenceString.Equals("*SWITCHOUTPUT*"))
                            {
                                SwitchOutputFromAnalogue(i, false);
                            }
                            else
                            {
                                SendAKeySequenceToAProgram(AIDynamicButtonList[i].LOW_KeySequenceString, AIDynamicButtonList[i].LOW_MainClassString, AIDynamicButtonList[i].LOW_MainWindowString, AIDynamicButtonList[i].LOW_SubClassString, AIDynamicButtonList[i].LOW_SubWindowString);
                            }
                        }
                        else if ((!goingup) && diff < (-1) * AIDynamicButtonList[i].LowSwitchValue)
                        {
                            //There is more voltage, and the change is greater than the histeresis, so do the down command
                            if (AIDynamicButtonList[i].HIGH_KeySequenceString.Equals("*SWITCHOUTPUT*"))
                            {
                                SwitchOutputFromAnalogue(i, true);
                            }
                            else
                            {
                                SendAKeySequenceToAProgram(AIDynamicButtonList[i].HIGH_KeySequenceString, AIDynamicButtonList[i].HIGH_MainClassString, AIDynamicButtonList[i].HIGH_MainWindowString, AIDynamicButtonList[i].HIGH_SubClassString, AIDynamicButtonList[i].HIGH_SubWindowString);
                            }
                        }
                    }
...

So I took that, and made it into logic statements. I havent tested it or anything, but it should work.

My dad has been in town these past 2 weeks so I have been doing a lot of family things ontop of everything else. He leaves tomorrow, so I will have some more time to spend.

I should note that the hysteresis value is set large right now and the do statement that sends a U is when you want the volume to go up, and the one for D is for down. You will need to change those to the real then/do statements for controlling winamp.

Also make sure in the one that does multiplication it stays "-1" and not just "1". I found a bug in the config that pops up some times, but I need to get to sleep as I need to wake up in less than 2 hours to see my dad off. I'll try to fix the configurator bug shortly...
