ANNOUNCE: Squeezelite-ESP32 (dedicated thread)

[StevenEllis]

Here is the correct config with BT enabled that works with my headphones. I can't get the device to detect any of my BT Speakers, even if I override the a2dp_sink_name value

@sle118 did you have a chance to look at my config. Really puzzled as to why I can only see selected BT devices.

Is double pressing a a button implemented? I see it mentioned for rotary encoder, but not for regular buttons.
Can that be added in a future update?

No it's not - it's a bit of a hack in Rotary. It's not implemented at the core of the buttons management, more in the "applicative" layer of the Rotary and thus it's not scalable

GPIO to control amplifier power

I remember I have read something about ist, but could't find it anymore.
Maybe somebody here just knows it ?

Is there an option to confgure a GPIO which can be used to control amplifier on/off ?

[Paul Webster]

From the docs that are linked to from the first post in this thread

The <amp> parameter can use used to assign a GPIO that will be set to active level (default 1) when playback starts. It will be reset when squeezelite becomes idle. The idle timeout is set on the squeezelite command line through -C <timeout>

See the docs themselves for how to set it up.

The option that is mentioned by Paul above is described here:

Thanks, found it. Now the next question.

I would like to use GPIO0 and I would like to have it compile time.

Did make menuconfig, added the GPIO, after building I checked 'sdkconfig' which now contains the following entry: CONFIG_SET_GPIO="0=amp:1"

When measuring GPIO0, it remains high and when checking the log with telnet, the only (more or less) related message I can find is:

"[00:05:38.189675] output_thread_i2s:452 switching off amp GPIO -1" I would expect this would list GPIO0.

Did I do something wrong with "CONFIG_SET_GPIO" ?
Are there any other options to check GPIO allocation ?

<< Update >>
After some trying I noticed that adding the "active high/active low" level ":1" cause the GPIO not to be recognized.

So '0=amp' works '0=amp:1' does not work. Is it a misunderstanding from my side, os just a bug ?

You're correct, there was an issue with the amp gpio parsing when polarity was set. It's corrected now

Unfortunately, I've been missing in action in the past few weeks with real life (TM) catching on and depriving me of sleep at times

No worries I fully understand. Really appreciate all the hard work.

Hi there,

I want to try Squeezelite-ESP32 at my home, so I ordered at first an ESP-A1S which should be good for some testing.
At the end I want to connect at least one device via S/PDIF (AV Receiver) to that client.
Is it possible with the ESP-A1S? Or do I need a ESP32-WROVER Kit?
And what kind of external module should be working without any problems?

Thanks :-)

OK, so if I understand correctly:
I can use any of the GPIOs for the I2S Output and I need to configure only "bck=<gpio>,ws=<gpio>,do=<gpio>"?
From this three only DO needs to be connected to the external DAC (+ ground, of course)?

Any recommandation for an external DAC module?
With fast search I found a "DollaTek HIFI DiGi+" module?

The A1S already has a DAC inside, that’s the main reason for this A1S module. Are you talking about i2s or spdif then? If this is spdif you don’t need a DAC on the esp32 side, it is part of the équipement you connect the spdif to. If you still want your own DAC, why connecting it’s with spdif rather that i2s gpio and why not using a plain esp32 then?

I've chosen the ESP32-A1S as this was the first board, which I found. But for one use case it's also ok as I want to connect it via headset output to another device.

But for the other use case I want to use a SPDIF connection (optical or coax, doesn't matter) to my AV-Receiver. So if I understand correctly an ESP-WROOM-32 should be enough. Then I need an external module with SPDIF output and the connection between the ESP32 and external module is I2S? Or did I understand wrong? And which module could I take?

[Paul Webster]

The docs say ... "For the sake of clarity, WROOM modules DO NOT work as they don't include PSRAM. Some designs might add it externally, but it's (very) unlikely."
