12bit PWMParabola?

[rimai]

There is no support for the 16 channel on our libraries. You need custom code as I mentioned before.
AlanM has started this though:

Take a look at this code to see how to do it without the libraries integration:

Thank you!

Any sneaky pitfalls I should be on the look out for when I add in the custom code?

[Meldrath]

Okay, I finally got my code to compile correctly using Kraven's library.

Code: Select all

     int i = 0;
    
    while (i < 100)
    {
      ReefAngel.PCA.SetAllChannelsPercent(i);
      Serial.println(i);
      i++;
    }
    
    while (i >= 0)
    {
      ReefAngel.PCA.SetAllChannelsPercent(i);
      i--;
    }

The problem is when I hook up my adafruit breakout chip to the i2c port on the relay, I get a steady blinking red light under status and it does not dim up/down like it should.

I have tried my best to diagnose the issue, but am failing to see what the issue is at the moment.

To verify: I did create my own usb to i2c cable, with the following configuration;
Black - Ground
Green - SDA
White - SCL
Red - VCC

[Meldrath]

Shameless bump to figure this out. Any help from anyone would be appreciated.

[rimai]

Did you try inverting the SDA/SCL wires?
It's something in the bus that is causing this.

[Meldrath]

I did. The chip is set to 0x4e (I believe) so I set that in the globals and moved the PHProbe to a different address.

Could this be the source of the issue?

[rimai]

Can you confirm the breakout board is working with another arduino board?

[Meldrath]

Not readily available.

[rimai]

The address won't be the issue.
If the status is blinking, it means your bus is locked.
So, I know it is something in that cable you've made or it is the breakout board/chip that is non-functional.
Burned out chips can cause this too.

[Meldrath]

Is there a verify within reef angel or something to see if the chip is functional?

[rimai]

Yes, there is a code called i2cscanner. If you search the forum, you will find it...
But it won't work in your case because the bus is locked.

[Meldrath]

I had a 2nd one, I wired it up, and ran the i2c scanner.

My chip is set for 54 (which is the same as eeprom 2, which I set to 5d)

[rimai]

You need to change your chip to another address. You can't use one that is already in use

Did that now, and it's still not working lol.
