Well i think i have a bug. Ive experienced this a couple times. I noticed today that my lights were not changing in intensity. Not sure when it started everything else is working fine. So i test to make sure the pca was getting signal from pi. It was.
Well maybe my pca9685 is bad put a new one on still nothing. Well let me go delete it and re add it. Well i forgot to delete the jacks before deleting the driver.


The picture is what i get now under the connectors tab. Cannot get past it unless i delete database and start over. Ideas?

Hey guys I was hoping someone can help me with PWM stuff. I can't seem to figure out how to make it work using reef pi. Here's what I've done. I did a fresh install. Noobs 3.1.1, reef pi 2.4. I updated everything before I installed reef pi. I went into config.txt and configured the pwm by adding code into the text. I am using the raspberry and I get this code and nothing works, thanks for the help

Can you reboot ? And if the issue persist share the log

Yes, if I understand correctly this is a bug related to missing validation, reef-pi should not allow deleting drivers without deleting the associated connectors

I've rebooted a couple of times not sure on how to share the log

I am having the same problem adding the pca9685, had it running fine on 2.3 but updated to 3.0 alpha 2 and keeps giving error messages. Not sure if these images are what you need to help diagnose this problem but here are some

guess I should add I have tried restarting several times and have even wiped the sd card and started new

You have to delete your reef-pi database if you are planning to upgrade to 3.0, and do the configuration again. In 3.0 you have to create a driver first, and then associate jacks with it. One the plus side you can use pca9685 as outlet , other than typical jacks

@Ranjib if you are talking about this then it has already been done
Sudo apt-get remove reef-pi -y --purge
Sudo rm -rf /var/lib/reef-pi
Is there something or somewhere I'm forgetting?
I did both of those, restarted, downloaded and installed 3.0, restarted again. Had to put in EVERYTHING fresh

Yes, that’s it.

By the way, a very warm welcome to reef2reef :-)

 

[alphacustomization]

Thank you for the welcome
Any idea why it won't load the pca9685? I was going to try to format the sd card again tomorrow and reinstall from scratch to see if that will take care of the problem, maybe I made a mistake the first time

What error you are getting? I2c is enabled ? Do you see the address via i2cdetect ? Does the chip shows red led light on ?

 

[Ranjib]

In 3.0 you have to create a driver first , then associate that with jacks

HI
still in the testing phase
i was getting (ERROR {"error":"Failed to create. Error: write /sys/class/pwm/pwmchip0/pwm0/period: invalid argument"} | HTTP 500) when i tried to add jack at channel 0
running reef-pi 2.4 pi3 on raspberry pi 3b+
after i searched for answers and couldn't get a clear one i upgraded to pi 3.0.0 pre-alpha 2
i was able to add the jack and run the test OK
then noticed that in the config page under setting i don't have pca9685 anymore
when i tried to add it from driver tab using the default poar 68 and frequency 1500 i got
error":"Failed to create. Error: remote I/O error"} | HTTP 500

any help would be appreciated

Hi
Still during the testing phase
was running reef-pi 2.4 on raspberry pi 3B+ and got error http 500 while trying to create jack at channel 0 after finding no clear solution i upgraded to pi 3.0.0 pre-alpha 2 and was able to add the jack easily and tested the PWM successfully. however i noticed there is no pca9685 support in the setting by default so i tried to add from the driver tab using the suggested address 68 and frequency of 1500 then i got this error
error":"Failed to create. Error: remote I/O error"} | HTTP 500
any help would be appreciated
thanks

 

[DaveWasabi]

Still having the same error, Alaa?

 

[Alaa]

Still having the same error, Alaa?

Yes
The first error occur with pi 2.3 and 2.4 and not corrected with updates and reboot
The second one with pi 3.0.0 alpha 2 and not only with pca9685 but with other drivers as well

You have the Pca9685 board connected to the pi?
I think Max frequency for pca9685 is 1000, see backside of the board
