Toon speaker

Apperently the Toon hadware has a speaker connected according to the hardware manufacturer.

Anyone tried to get the speaker working? Would be cool to be able to make some sounds sometimes...

There's no kernel support for the speaker in toon, at least not in the kernels provided by Quby. I will try and build some modules to get the speaker working. Will need a kernel replacement for that as well, because Quby have switched on module versioning.

I had a look at the speaker today. This is the device:
https://www.amec-gmbh.de/images/amec-me ... -1224B.pdf
It's the SFM-1224B 03. It's not exactly a high-end surround sound system. Probably capable of making a buzzing sound (alarms etc) but no real sound reproduction. With a little luck, it's wired to the processor's sound mixer.
I built a kernel with sound support, now I'm looking into some simple software to actually make some noise...

Cool..... even if it is just a beep. Alarm functions could be handy....or connect it to Domoticz stuff.... This low level kernel/driver stuff is out of my league but happy to look into QML apps later on ;-)

I'm afraid so, there won't be a lot to choose from.
Just installed a modified kernel and a bunch of modules for the sound subsystem, and ALSA utilities. This is what I get from amixer:

Hmmm ...

It's a slow process.

I recompiled the kernel + modules to contain the snd-soc-imx driver. Built all the ALSA tools, installed the lot (again), the whole shebang boots (using the newest zwave and wifi drivers from Quby ;-) ), the hardware is detected properly, and the ALSA tools detect the correct sound interface:

Code: Select all

toon:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: cpuimxaudio [cpuimx-audio], device 0: aic3100 aic3111-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
Now I need to find a configuration script for the sound hardware.

Will keep trying, but don't hold your breath ...

Cool,

we also need some sort of an interface layer between QML/Javascript and the hardware (out of my league).
While you are that, could you possibly look into including QtWebsockets in that build?
This will allow realtime communication with QML on Toon from the outside (e.g. Domoticz or others).
Absolutely not sure if that is even possible at all but I thought it's worth the ask.

Regardz,

Toonz

I don't know (yet).

The qt build on toon allows plugins, so if these subsystems can be built as plugins, it should be possible.
The whole qt build in openembedded is quite a challenge in itself (a sheer infinite number of libraries and other parts). It's on my list, just hasn't made it to the top, yet ;-)

So how about just getting it to play via aplay? Just as proof of concept? Can we get it to play sound/beeps at all?

An insane amount of options for just a beeping device.
(for reference, this is what my laptop can do: full stereo, record, playback, synthesize, the whole shebang:)

Anyway, will try to make some sense of it and get the beeps going :-).
Hi marcelr,

Do you really need the kernel soundsystem and ALSA modules? According to specs I found it's just a continuous buzzer, isn't it driven with a simple PWM output?

Correct, but you will still need some software to drive it. Linux only has the sound stack (ALSA or other) to make sound, even if it's just a single beep.

So no use of a GPIO driver like this one: gpio-beeper: drivers/input/misc/gpio-beeper.c is used to provide a beep from an external speaker connected to a GPIO line.

Could be, but then you need to know to which GPIO line the beeper is connected. Do you?

Nope, but I could open the Toon and give it a try... :D
