reef-pi :: An opensource reef tank controller based on Raspberry Pi.

Both are likely broken in different ways. There is a larger change coming to the PCA9685 driver which may fix the other half of the issues.

Sorry for finding a few bugs but someone has to do it

Spent some time poking at the PWM support, and can confirm the math... doesn't work at arbitrary frequencies (the frequency is written out as the period value multiplied out, and not the inverse as it should be). This also maps to the duty cycle being very wrong at frequencies not == 100.

This corresponds with my meter getting strange duty cycle readings. The frequency readings were confirmed with 2 seperate meters, but my second meter doesnt read duty cycle so didnt report that without confirmation.

thanks just trying get it back moved here a couple years ago lost all my sps coral in the move going soft coral this time, here are some pics of old tank

Beautiful!

No worries :) Bugs need testing to reveal.

I have a PR up and will see if we can back port this to a 2.x release.

Very nice!

No problem.
Have we been able to confirm whether 2.2 supports non-default PCA9685 i2c address?

nope :-/

did I get it all right I want to start putting mine together just need to know I'm seeing and reading it right

Do you need the exact same configuration? i.e. 3 kessil light and 12V moon light ? I would recommend not mixing them, and just go with only kessil or only mosfet (moonlight/led strip) circuits. Circuits involving PWM are very prone to aberrations. I am having a hard time reading the tiny texts, but I think they are mostly correct, or I could not spot any wrong labeling from the first look

it was late when posted I think may read better.

other can be removed

I'm going to start a build post soon. I just need know I'm seeing it all right
Mine will have changes to it.

@lotus02 have you seen the adafruit guide? The circuit layout has pretty detailed diagrams. https://learn.adafruit.com/reef-pi-lighting-controller/circuit-construction

Agree, the fritz diagrams for the most part detail the circuit construction, however it's only a starting place, most of theses circuits can be done in multiple ways. I'm not an electronic person either but what I found helpful is instead of just trying to duplicate things to try to understand the components and how it works. Takes more time depending on the circuit but makes things easier in the long run.

Have look at the 12v to 10v board layout and the finished board picture to me it looks like only have of it is there but I'm new to this so I thought I would make a PowerPoint file of what think is right. Could not load the file on here so I converted to pic files and posted them. Let's just say if took the layout diagram and put the part I see on it than pull up the picture after they would look the same. But with all that was put in to that with the pictures and the writing up on how to do it think I got
Like I said I'm new and if I start soldering stuff together I'm wrong it's a waste of parts.
Again thank you for making the DIY files.
I was think other newbies like me may get something out of the pictures I made?

 

[lotus02]

All the other diagrams see how it will make what's in the pictures of the finished board
I was just having a hard time with that power board.
Again thank you to all guys on here for the help.

I have a feature suggestion. I just realized I went the past 4 days with my alkalinity doser disabled. I have a second alkalinity doser rule setup for adjustment and meant to disable it but disabled the one above it instead. The way the drop downs are sometimes its confusing which timer you are working with the one above or the one below. It might be nice to have a disable button next to the calibrate, edit, delete buttons. Likewise it would be nice to have the same next to the timers edit, delete buttons. It would be handy to have a quick button to instantly disable instead of opening up, editing, then selecting the drop down to disable.

Just a thought

 

[lotus02]

In the end mine will be different as I will not have the board in the same box. And I will have a 10v power supply for the kessil lights 12v for moon LEDs. 5v to the pi and pca9685.
This is what I will or try to control:
5 a360we kessil lights.
6 mars black boxes
2 T5 with 2 bulbs on each run at different times
Moon light LEDs
Temperature prob controls heater
Float switch to turn a light on if level low and email me if low and if temp is out.
My phone keeps changing what I type

Sounds reasonable. You mind filing an issue on the repo (https://github.com/reef-pi/reef-pi) ?
