PWM Expansion difficulties

So I've been trying for the past day and half to figure out how to set my LED lights on a dimming schedule. So far all I've been able to do is turn them on and off. I've changed to code during my experiments to have the LED's run at only 30% so that I can visually tell if the code is working....but so far they keep running at full power...my brain is fried from reading posts on the forum and trying to figure this out...any help would be awesome!
Not looking for anything fancy right now...just want a sunrise/sunset effect...

Your code looks just fine to me.
Did you place the jumper on the head unit?

Actually, I'm sorry.
Tired today. I should go rest for a bit....
On 2nd look, the code is actually not doing anything.
Try this:
Code: Select all
#include <ReefAngel_Features.h>
#include <Globals.h>
#include <RA_Wifi.h>
#include <Wire.h>
#include <OneWire.h>
#include <Time.h>

#include <RA_TempSensor.h>
#include <Relay.h>
#include <RA_PWM.h>
#include <Timer.h>
#include <Memory.h>
#include <RF.h>
#include <IO.h>
#include <ReefAngel.h>
////// Place global variable code below here
////// Place global variable code above here
void setup()
{
// This must be the first line
ReefAngel.Init(); //Initialize controller
// Ports that are always on
ReefAngel.Relay.On(Port2);
ReefAngel.Relay.On(Port5);
ReefAngel.Relay.On(Port6);
ReefAngel.Relay.On(Port7);
ReefAngel.Relay.On(Port8);
////// Place additional initialization code below here
////// Place additional initialization code above here
}
void loop()
{
////// Place your custom code below here
//Start of PWM Expansion Code for Slope
ReefAngel.PWM.SetChannel(0,PWMSlope(11,00,17,00,20,80,60,0));
ReefAngel.PWM.SetChannel(1,PWMSlope(10,00,18,00,20,80,60,0));
ReefAngel.PWM.SetChannel(2,PWMSlope(9,30,18,30,20,80,30,0));
ReefAngel.PWM.SetChannel(3,PWMSlope(10,30,17,30,20,80,30,0));
// The lines above are what calculates the slope.

No changes Roberto...lights still pumping full power. Not sure if this matters much, I figured a ground is a ground...but...when wiring the PWM Expansion Module everytime I hooked the 12V Adapter ground wire to the ground on the Module the adapter shorted out. Right now I have all 4 drivers hooked into channel 0,1,2,3 on the Module and the 12V adapter hot wire in the +12VDC spot and all the ground drivers plus the ground from the 12V adapter soldered together, separate from the Module. When I do it this way the lights work...not sure if this is the reason why the lights aren't dimming...what do you think?

Yes, this is the reason.
You need the ground reference from the module to be the same as everything else and leaving disconnected you create 2 ground references.
But it should not short out when you connect the ground.
Can you descrive what happens when you say it shorts out?

Ok, after the + wire is hooked on the +12VDC spot on the module as soon as I touch the ground wire to the module the green light on the adapter goes out...figured it was shorting...

Yeah, that is definitelly not normal behavior.
Does it do the same thing even without the drivers connected?
PM me to send it for repair.

Thanks Roberto, just got your package in the mail, installed the module, hooked the wiring up...everything works like a champ! Thank you again for all your quick responses and great service!

Cool. Glad it's working
