But when I write a value to the chip, it's not actually doing the pwm for that value. It's just staying at that default value. The registers are taking the new value, but the pwm isn't going to the new value. I believe the chip is in restart mode or somehow the oscillator was turned off. From the da...

It's all the channels, and Kraven verified the registers are receiving new values. As he was able to read and write to all of them.

Have you guys ever encountered having a 'stuck' pwm value in the pca9685? It persists through power cycles, and I've tried to understand the data sheet for it. The best thing I can come up with is it's in restart mode but I don't quite get how to send the appropriate signals to it to reset the chip....

As an fyi, to do that, you're going to have to either create a new call/write methods or you're going to have to change the existing ones. (I went with adding a new expansion/pwm slope/pwm parabola methods)

Why not overload the Expansion function to accept an int from an overloaded PWMSlope function? Or... You could overload PWMSlope and call the expansion function directly from the PWMSlope and not have to deal with conversions per se? Or will that not work in this case? Further, I have Kraven's libra...

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

I had a 2nd one, I wired it up, and ran the i2c scanner. I2CScanner ready! starting scanning of I2C bus from 1 to 128... addr: 1 addr: 2 addr: 3 addr: 4 addr: 5 addr: 6 addr: 7 addr: 8 addr: 9 addr: A addr: B addr: C addr: D addr: E addr: F addr: 10 addr: 11 addr: 12 addr: 13 addr: 14 addr: 15 addr:...

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

Not readily available.

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?

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

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

Alan, where are you at on this?

Thank you!

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

I did compile it first inside of the Arduino IDE and that did nothing. I added the #define to the Globals.h under the device type and that seemed to work.

Further, I did look in the ReefAngel_Features.h file, and #define DCPUMPCONTROL is not available in there anywhere.

Okay, i'm just a little more then slightly confused looking at the PWM class, how is this 16 channel capable when only 6 channels are defined in the library? The global variable #define PWM_EXPANSION_CHANNELS is 6, and the Internal EEPROM is only defined out to PWMChannel6 at 0x480. Can you provide ...

In visual studio 2012/2013 it shows ReefAngel class not having the method DCPump(). I am using the Visual Micro Plugin. Everything else loads fine and has the correct associations.

Any advice or help on this would be appreciated.

Roberto, how do you set it up with 2 chips?

v1.0.7 includes code to use that chip :) Set your chip to I2C address: CODE: SELECT ALL #define I2CPWM_PCA9685 0x40 Now, you can simply call: CODE: SELECT ALL ReefAngel.PWM.SetChannel(0,50); // Set channel 0 to 50% The libraries will do the heavy lifting for you :) I don't have my RA in front of me...

If just the green light is blinking slowly, does that mean everything is OK?
