Reef-pi dimming controller

[figaro93]

[QUOTE = "Ryan115, post: 5602812, membro: 14533"] Nelle immagini originali vedo SDA e SCL connessi sul pi, ma sembra che nulla sia collegato a SCL sul PCA9685.

sisi I replaced the cables putting them respectively on sda and scl and I left free vcc

[QUOTE = "Ranjib, post: 5603088, membro: 67835"] Ok. Quindi viene rilevato pca9685, che significa anche che i2c è configurato. E il registro reef-pi? Cosa mostra il registro reef-pi quando si modifica l'attenuazione dall'interfaccia utente? [/ QUOTE]

dove posso leggere questo registro?

 

[figaro93]

Ok. So pca9685 is detected , that also means i2c is configured. What about the reef-pi log ? What does reef-pi log shows when you change dimming from the ui ?

where can I read this register?

 

[Ranjib]

where can I read this register?

raspberry pi terminal

journalctl -fu reef-pi.service

vcc needs 5v power

the error I get is Failed to initialize i2c. Error: open / dev / i2c-1: no such file or directory I must also thank the user who told me to enable pca9685 I was totally forgotten ... I also adjusted by sending 5v of current to VCC as you advised me however when I try to dim it does not correspond to what I command @Ranjib

When you dim, do you see reef-pi logs mentioning the pca9685 percentage? are you checking the voltage output from pca9685 pin. Can you share a screenshot of reef-pi log, while you dim from UI ?

This is my register of reef-pi

 

[Ranjib]

This is my register of reef-pi

that mean reef-pi the software is working fine, and most likely pca9685 board as well. I see you have set the dimming to 0%. Can you change it to 50%. And the use a multimeter to read the voltage from pca9685 output pin.

sure now I do it

finally my lights controller works perfectly. I explain my mistakes ... first error: I had not sent the 5v to the VCC connector but mistakenly had inserted the plug on the V + connector second error: I had not enabled the enable pca9685 in the configuration as soon as I enabled and made the raspberry reeboot it immediately started and started to dim as soon as I set the 50% setting on the pwm to 5v precise on fixed control in the light working area. Now I would have the last question because finally everything works :) how come if I set the fixed control to 0% instead of 50% gives me 10v on the pwm and then the object that I have in connection starts at most? I'm building a ceiling light to the LED and I would like the intensity to be reduced to 0v to shut off completely is there any other programming to use? STILL THANKS FOR ALL THE SUPPORT YOU HAVE GIVEN UNTIL NOW @Ranjib

and now either switch to the controller Ph <3

 

[Ranjib]

yay :-)
are you saying its working reverse? Or its not giving the full range? Check the active high/active low settings address your problem

 

[figaro93]

sorry but I can not understand I'm Italian and hardly speak your language ahaha

 

[Ryan115]

I think he is saying that a setting of 0% gives full brightness (100%).

Set the Min and Start values to 1 on the lighting tab, and have the lighting turned off at the outlet with a relay. Many lights will not dim down to 0.

[QUOTE = "Ryan115, post: 5604447, membro: 14533"] Penso che stia dicendo che un'impostazione dello 0% dà la piena luminosità (100%).



Impostare i valori Min e Start su 1 sulla scheda di illuminazione e spegnere l'illuminazione in uscita con un relè. Molte luci non si oscurano fino a 0. [/ QUOTE]

How can I do what you have told me?
could you explain me?

Are the lights running through a relay that reef-pi is controlling? If so, then you can have that turn the lights off in the timers tab.
In the example below, I have my dimming set as you see, but my lights are turned off/on at the power source @0830 and @1945

In the lighting tab, you will see the min value and start value boxes. Set these to 1.

@Ranjib will this override all of the 0's in both the auto and fixed settings?

I have relays available on reef power control plus it has a separate board ... you say that I should also insert a relay to the control board lights to help turn off?

If your lights are unable to dim to 0% then you will need some other way to turn them off. This can be as simple as a wall timer, which would be independent from reef-pi, or run on a relay controlled outlet from reef-pi.

I finally managed to solve the problem ...
I connected a led strip and I modified Behavior selecting Active Low and everything works perfectly ...
I'm really so happy ..
Thank you so much for helping me
I wanted to ask one last thing.
But you can not create lightning or storm scenarios with reefs pi?
I would like to recreate them with my self-built ceiling light
