Request: Will there be support for the ESP32-Wrover Module and/or SPIRAM Flash 32 Mbit

[SinglWolf]

Hi! Will there be support for the ESP32-Wrover Module and/or SPIRAM Flash 32 Mbit? This ESP32-Wrover Module (or a separate SPIRAM chip) allows you to organize a playback buffer for up to 8 seconds. Very useful for bad internet connection. If you plan to enable SPIRAM support, let us know. Give thanks.

I do not have a module with SPRAM, so I can't test it. However, there is normally some 200 KB feer memory available, so why not increase the queue. See line 185:

define QSIZ 400

You may try a setting of 5000.

Thanks for the answer. I ordered a module with additional memory on Aliexpress. I will check your recommendation and be sure to report the results.

[SinglWolf]

Good day! Fulfilled your recommendations

#define QSIZ 5000
.....
dataqueue = xQueueCreate(QSIZ, // Create queue for communication
                           sizeof(qdata_struct));
......

and got a cyclic reboot

Increasing this parameter is a bad idea. Because it sets the maximum number of items that can be stored in the queue at any time. Need a dynamic buffer, I think. I do not know how to implement it. Not enough knowledge, alas.

[Edzelf]

A queue IS a synamic buffer. But I agree that a big buffersize will not solve sync problems.

Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3, and AAC files on I2S DACs or with a software emulated delta-sigma DAC on the ESP8266 and ESP32 Please see this project. There is clearly external SPIRAM support for ESP32. Namely files src/AudioFileSourceSPIRAMBuffer.h and src/AudioFileSourceSPIRAMBuffer.cpp .

[Edzelf]

Yes, but what is the point? There's no real memory shortage.

[SinglWolf]

I would like to have a large buffer for the audio stream with a bad Internet channel. There is the Ka-Radio32 project, where external memory is used and determined automatically. But the framework ESP-IDF is not available for my understanding. With Arduino, I still somehow cope. I can not impose my opinion on you. Do not want to implement support for psram is your right. Thanks for answers.
