Good plan. I'll see which is easier lol

NTP primary and failover/backup server implemented. Edited code on page 12 of thread.

You could just split the difference...

I'm not sure anyone will even use this code or module. But I figured it was worth posting. I've got the backup NTP server in the code. Which reduces odds of NTP time failure. Might add a few more to completely remove the possibility

Roberto: One last thing I would like to do...

Any way for the ethernet module to send a PWM percentage to make the portal "think" it is a Radion value? I would like the percentage to display on the portal under "Red" for PWM pin 9 value and "Green" for pin 6 value.

I've tried to think of ways to accomplish this, but I'm coming up short

Thanks as always!!

P.s. the code has change a bit versus page 12 of the thread..but it's basically still the same as what you see on page 12 at the top.

You need to do that in the main unit for it to work.

CODE UPDATE:

Corrected code for potentiometers to override PWMParabola to allow for manual dimming of pin 9 and pin 6.
Return both potentiometers to "0" to have PWMParabola take back over...

Also looking for suggestions/improvements/thoughts. If you have implemented this let me know too!!!

I've been playing with the idea of how to send info from one arduino to the RA. I'll use the serial communications. I need to send a BYTE and then have the RA receive the byte incomingbyte incomingbyte=Serial.read();
But here is where I'm coming up short. What do I do with the byte once it is read? How do I get this to replace the "0" on RFR and RFG (radian values). of course I'll have different bytes of info for each.


Also, related to this thread:
I've gotten a Chinese version of the Uno/Ethernet combo. It is working great thus far and is a CHEAPER option for everyone at $25 (shipping included) versus $60(+or-) +shipping for the one I've been using so far. Super easy to patch the wifi cable into it FYI.

SetChannel(byte channel, byte value) seems to be the function to write your byte to whichever radion channel you want. The rest of the functions in the RF class are for setting slopes.

hmmm...so in theory. I write the received byte to SetChannel() and it'll display on the portal? This is me trying to "fool" the portal after all to know my % of brightness off my ethernet module lol...I'd just prefer to know my % values at a glance versus Serial.print() I have to use now.

Yeah, it should set the channel even though nothing is written there.. Theoretically, there may be other code in the way that Im not aware of.

Hey, thanks...it's been updated!

Sorry losing my mind....

Updated page 12 of thread.

Which thread? what did you update?

EDIT:
I should have been more clear...

Security option issue with the portal and Ethernet module. It must [<--Not 100% true] be disabled. That's all I added


I don't use security....but anyone can add this to the RA side of the code...

Use below for security option (IF needed):
ReefAngel SIDE
"key" must match on code and portal

I have been using this for a few weeks and it really does work well. I am having a problem with the pwm for my Leds. They light up fine, but they flash, it's so fast that I thought it was just glimmer at first. I am using steve's led drivers. They work fine straight off of the RA dimming. Any suggestions?

Sounds like you don't have enough LEDs in the string. The driver is "protecting" itself. Either reduce the mA output from the driver or add more LEDs. That's what it sounds like to me

can't be that. They work fine off the RA, and the drivers are maxed out as far as capacity.

Could be that you need an opamp to boost from 0-5vdc to 0-10vdc. Roberto posted a circuit for how to do it

Or make sure they don't send more than 40mA to the arduino. I don't use Steve's so I'm not sure.

That might be it. I wonder what he uses for the relay that makes it work.

Lm358 opamp. Two 10k resistors make a gain of 1.

The drivers I am using will work straight off an Arduino pwm. In fact they can even supply +5v to power the board. I think it is either some sort of noise induced from the power supply, or the pwm freq. is too low?

Not sure.

Try to remove this line or //comment it out:
And check this page out:
http://arduino.cc/en/Tutorial/SecretsOfArduinoPWM

Commented out, same problem. There must be something causing it.

If I remember correctly, Steve's drivers accept 0-5V PWM too, doesn't it?
Can you describe or post a video of such flickering effect?
Do you have access to a scope to check the signal?

No, scope available. The drive does except 0 - 5v pwm. I can record it, but it looks like a strobe light a very fast flicker with no perceived off.
