thanks Alfred -sorted!

@Alfred-Riss said in Control GPIOs from simple web page:

https://docs.onion.io/omega2-project-book-vol1/led-traffic-light.html

Thanks- I had seen this but I need to use a web browser/html to do this.

Ahh - think I have found something related to node.js that might do it.

Just wondered if its possible to control GPIO pins from a simple web page button/html?
E.g Call gpioctl command to toggle output
I'm sure I saw this somewhere, but can't seem to find it now.

TIA

@crispyoz said in is Nano available on Omega2?:

/etc/opkg/distfeeds.conf

Ahh thanks again .. :). I was wondering which feed it was in!

@Denis-Mikhalsky

For playback into a pcm1502a board the wiring here will work:
https://onion.io/2bt-omega-i2s-audio/
You can ignore the setup stuff, just use UFDs build and it works.

@UFD
What are you recording onto? bigger also buffer or making the process run as a higher priority can help.

I tried your build as I have also spent ages trying to get i2s audio out
and it does work well with my 1502 board( own design) - thanks.

I never got any official reply on whether i2s audio I/o would be part if the 'factory' builds... There is project in the docs that says i2s audio is included and shows
a setup , but its out of date and doesn't work.

I'm looking at manufacturing a combined pcm1502a + pcm186x board
and currently considering the omega2+ as the host processor.

Can't find the nano editor in the package list, although it seems some folks have it installed.
Any idea where to get it?

TIA

Thanks Chris - I was not aware of the hotplug stuff. omega2 is pretty slow to boot
up for a little openWrt device(1 min+)

anyway I think I have something working so far.

is it possible to detect when the network is up? I need to run a script in rc.local
but it needs to have the network connected (either Access point, or connected to my home network) first.

TIA

@crispyoz
Spent the entire day doing this but never really got a build system
going. Spent ages correcting endless errors and various problems.

I won't waste any more time ( or anyone elses) on this.
I'm not going to use Omega for this project.

Thanks to all for trying to help.

@UFD said in Most recent stable build with i2s ??:

(However @Lazar-Demin should consider adding the 2 main ones found in the hobbiest space i.e MAX98367A and PCM5102A).

Thanks everyone for the help/info. Thats what was confusing as I thought these were
included. Anyway, last time I did some source building a few years ago It was fairly slow and painful LOL . I guess a dynamically loaded module might be the way to go.
I'll let you know if I decide to try this.

@UFD thanks . Yes, sorry of course it should be i2s not i2c (although some codecs need i2c for control) I am using a PCM 1502A DAC which I use a lot with other boards. Also have the MAX98367A mention in the article on i2s audio.

@crispyoz said in Most recent stable build with i2s ??:

opkg install kmod-i2c-core

Yes that is there:
Package kmod-i2c-core (4.4.74-1) installed in root is up to date.

Unfortunately the lines were uncommented, and it still does not work.
Something is there, but I have no idea what to try next.
ALSA says no sound card.

@crispyoz
Thanks! I will give this a try.

Hello everyone - looking forward(hopefully!) to using omega2+ in several upcoming projects.

first is audio. I saw this in the Onion doc/info:
https://onion.io/2bt-omega-i2s-audio/
("...the very latest release of the Omega OS has support for I2S audio devices")

However latest stable, and latest bleeding edge don't seem to have i2s.
Tried it but no i2s /alsa sound card.

so ... what is the most recent stable firmware with working i2s?

I see some stuff about hacking together old firmware that might make it work
but this ( and USB audio) are things I want to avoid for now.

I notice i2s seems to be suspiciously absent from the documentation ..

Thanks.
