Stuggling with the LDD Drivers

[newtoke]

I already ordered two 1000ma Steve... Thanks for the offer. I ordered the PWM Expansion Module, because it appears that is the only way people are having success... I would though hope that Roberto will add the ability to modify the voltage out of the relay pack PWM outputs in the future.

[Sacohen]

No Problem. Good luck with them.
I have 4 that I need to get motivated to set up.

[newtoke]

Sigh... it didn't seem to work. I put those two lines you mentioned before the "interface" method. This is what I did:

Code: Select all

//ATO PWM output
  pinMode(lowATOPin, OUTPUT);
  pinMode(highATOPin, OUTPUT);
  analogWrite(lowATOPin, ReefAngel.PWM.GetActinicValue() * 2.55);
  analogWrite(highATOPin, ReefAngel.PWM.GetDaylightValue() * 2.55);

  // This should always be the last line
  ReefAngel.Portal();
  ReefAngel.ShowInterface();

I am ordering new drivers in case I fried them. Any other ideas? I'd really love to find a testing device that can generate a PWM signal and a device that can test a PWM signal, but I have yet to find any.

Roberto any thoughts on this code?

[rimai]

Code looks fine.

Doesn't work... Only thing that happens is that the lights go out. Hopefully the dimmer module I just purchased will solve this?

[blert]

Sigh... it didn't seem to work. ...

The LDD drivers and the controlling device MUST share a common ground. You can't just send them a signal and have them work, they need to be properly hooked up electrically.

[newtoke]

I know the ground from the RA ATO port was connected to the -Vout on the power supply. I was trying to use Roberto's suggestion of having using the ATO as a PWM 5vdc signal using the code shown in earlier in this thread, but the lights would just stay dark.

[rimai]

Do you get any voltage when you measure the ago ports?

I went ahead and purchased the Dimmer module. I opened it up and put in the 5 vdc jumpers. I wired ther LDD white wire to the dimmer and the negative or ground of the DImmer module to the negative VOut on the power supply and the lights don't turn on at all.

If I disconnect the white wire from the dimmer module then I get 100% full on from my lights

[rimai]

Did you change your code to use the dimming expansion module?
Can we see it?

[newtoke]

Code: Select all

  ReefAngel.ActinicLights( Port5 );
  ReefAngel.MoonLights( Port4 );
  ReefAngel.PWM.DaylightPWMSlope();
  ReefAngel.PWM.ActinicPWMSlope( 60 );
  
  //Moon output
  moonPWM = Moon.MoonPWM(0, 20);
  if (moonPWM >= 1)
  {
    ReefAngel.Relay.On( Port3 );
  }
  else
  {
    ReefAngel.Relay.Off( Port3 );
  }

  //light temp
  int lightTemp = ReefAngel.Params.Temp[T2_PROBE];
  if(lightTemp > 1200) lightOverHeat = true;
  if(lightTemp < 900)
  { 
    lightOverHeat = false;
  } 

  //fan control
  if(lightTemp > 950)
  {
    //turn on fans when over 95 degrees
    ReefAngel.Relay.On( Port8 );
  } 
  else if(lightTemp <= (ReefAngel.Params.Temp[T1_PROBE] + 50))
  {
    //turn off fans when in five degrees of room temp;
    ReefAngel.Relay.Off( Port8 );
  }

  //driver control
  if (lightOverHeat)
  {
	  ReefAngel.PWM.SetChannel(0, 0);
	  ReefAngel.PWM.SetChannel(1, 0);
	  ReefAngel.Relay.Off( Port5 );
  }
  else
  {
	  ReefAngel.PWM.Channel0PWMSlope();
	  ReefAngel.PWM.Channel1PWMSlope(60);
	  ReefAngel.Relay.On( Port5 );
  }

[newtoke]

Oh and the code worked fine with my older meanwell drivers.

[rimai]

This code doesn't use the dimming expansion.
Try adding this to see if it works:

Code: Select all

ReefAngel.PWM.SetChannel(0,100);
ReefAngel.PWM.SetChannel(1,100);
ReefAngel.PWM.SetChannel(2,100);
ReefAngel.PWM.SetChannel(3,100);
ReefAngel.PWM.SetChannel(4,100);
ReefAngel.PWM.SetChannel(5,100);

[newtoke]

Isn't this the dimming expansion code?

//driver control
if (lightOverHeat)
{
ReefAngel.PWM.SetChannel(0, 0);
ReefAngel.PWM.SetChannel(1, 0);
ReefAngel.Relay.Off( Port5 );
}
else
{
ReefAngel.PWM.Channel0PWMSlope();
ReefAngel.PWM.Channel1PWMSlope(60);
ReefAngel.Relay.On( Port5 );
}

[rimai]

Oh.
My bad. I didn't scroll down the code.
I just looked the top part.
You are correct. They are for the dimming module.
What do you see in the screen for the channels 0 and 1?
Is it showing 0 or some other number?

[newtoke]

Its 100 as it should be.

[rimai]

I'm thinking it is something in your wiring or your driver.
Can you post a sketch of how you connected stuff together?

[newtoke]

[rimai]

If you disconnect the white ch0 wire, what voltage do you get on channel 0?

[newtoke]

I will have to check when I get back into work on Tuesday.

[newtoke]

I just checked it and I am getting zero volts out of each channel ( 0 - 5 ). To make sure my voltmeter was working, I then checked the ATO ports where I got 4.75 volts. So what am I doing wrong to only get zero volts?

Remove the jumper in the dimming expansion module that is all by itself.

[newtoke]

That did it... What did the jumper do?

[rimai]

Changes the address from 0x40 to 0x41.
Technically you can have 2 of those modules, but only one is supported with the current libraries.
