Internet radio and audio file player on ESP32-S3

Thanks for your time. Changing to RST 8 unfortunately didn't help anything, also no idea what else to do. If I've never had a problem with RST-1, then suddenly it couldn't have changed. In version 3.19.19 the sound is there, after switching off/on with the remote control too, so I think there is some babol in the module in the new code and this is where the problem is. Maybe some modules are more robust than mine.

Gentlemen the sound is on version 32 when switched off and started from the remote control. I have checked.

Greetings ...

I compiled again, but on the Arduino IDE, same symptom, no sound.

Hello,
Gentlemen, I have a question regarding the graphic equalizer and the EVO analyser, is there already a version that supports a full 16 point frequency equalizer with +-18dB gain and do you already have the analyser running for this project . If so, how is it activated, from the SD card or does it have to be placed in code? How do you have this implemented if I may know?

this is how I came up with a few small tweaks still but almost final state

@hevet, I have no idea where the problem is with this audio. I can't reproduce it at my place but as I said I will still try to build your connection configuration. With me, your code works - Platformio compilation. Further to the thread at Wolle's I also have no problems with BBC1 which I listen to, it doesn't reset my radio, the stream works very stably.

@ejcon The Evo has the 3 point basic equalizer that the i2s library provides (Hi, Mid, Low). There is also no spectrum analyser. There is only a VU.

@irysbox Very nice design. That lettering at the top is a laser engraving ? I was just wondering how an engraved case description would come out. Write something more. Oh well and brag about the contents what is inside

@robgold At Evo radio we use an older version of the library and this problem was not with the BBC, it appeared in some newer version and I use the latest one in my radio on ili9488. The author has already fixed the error.

Ok, thanks for trying to solve the problem. The only solution for now is to change to deep, disable the clock and clock timer at sleep so it doesn't turn on Disadvantages the radio wakes up with every button (probably something can be added to fix this), but at least the sound isn't lost....

@hevet my Evo is running on 3.4.3 and patches from 8.11 so fairly fresh. I've seen the buffer patches it did today. I've already downloaded (have a copy of the repo at my place) and will be testing. As a matter of convenience now in the latest Evo 3.19.38 one variable switches whether you want to use SD card or SPIFFS.

Ok, the error may have been in some commit from the last few days.

>>21750568 I managed to get such an equalizer in YoRadio and it works with the previous audio library. Is it not possible to do this with this audio library?

Attached is Tom's YoRadio soft with my added graphic equalizer and analyzer in the form of bars. Maybe you guys will find it useful for something.

>>21750656 yoRadio uses a very old version of the same library. I don't know how it is implemented there. Show the code how you did it we can think about it.

Added after 20 [minutes]:

@hevet For that, in the latest commit from today, google voice doesn't work, i.e. the clock Always something.

The middle is moderately beautiful because on a universal plate. There's nothing to be proud of with the usual cableology On the top it's a laser engraving so that it's minimally recessed and I pulled on the groove with an oil pen. If it was plexiglass it might have come out better, because because of the grooves after printing it blurs a bit on these irregularities, but don't pour too much. It is ok laser I have 24w. I was doing on a setting of 45 per cent power and 5000mm speed.

I once tried to resuscitate a Unitra avs103, but it didn't work the first time because my panel shifted and it started to smoke wrong where it needed to I had to grind off the oxidation and it went black already. A matter of feeling the power so that it doesn't melt the plastic but minimally sculpts it. Then white lacquer and it comes out not bad, but the adrenaline before starting is Before that you have to scan or graphically recreate the letters

Radio final version completed. Once again, many thanks to Majstra and Robgold for all their work and making the code available.
Regards.

Very nice workmanship. I am also considering a housing for the radio. Some idea is already there. Time will tell what will come out of it.... 😁
In general, nice enclosures are a problem for all builders.
What is the size of the front?

@efi222 exchange is 42 x 230 mm. You can read about this enclosure a few posts earlier.
Greetings

Read, read. The case is nice, just the price is a bit high.... I'll rather hit the 3D printing direction with additional machining.

@wieh76 Class case. Looks great, very professional.

As for this second arduino, in the current version of the radio you already have power OFF mode. You only need to set one output depending on the mode. Eventually there will be one in the software so you can control the relay directly from EPS. Current consumption in Standby is uA.

The second thing is that I have introduced support for SPIFFS memory so that in versions where the card is in the middle you can omit it completely. For those files that are required for the radio, 1.5Mb of space in ESP is enough.

The third issue is that there will be a second encoder option so you can connect it.

Forgive the question, but I haven't found anything clever. How to save the compilation in Arduino as bin instead of uploading to the board?

To DJCheester: "Aha, if you want to upload the soft coll Majster, you will need other libraries, which you have to download yourself via the library manager, but I can write you about that tomorrow, because today I can't remember them by heart."

I would be very grateful. And by the way, looking at GitHub, and the pix you need to upload /depending on the version/, I guess there are some inconsistencies?
Because, for example, I don't know which libraries and how edited to use for which version. And V1 is probably already completely wrong - unless I'm mistaken.
I wonder if anyone else is having problems like me?

I hope I don't get hit


To wieh76 -- Nice workmanship I like it.

@bolszoy no stupid questions, everyone learned at some point. Tab Sketch -> Export Compiled Binary and you have a BIN file in the directory where you have sketch.

You are great gentlemen

@ejcon There is a "Page1" in the code for testing just so that something can be quickly uploaded to the SD card and the HTML frontend can be fired up.

@robgold as for the arduino I used it because I didn't want the radio to be powered from usb only from a regular power supply via a regular mains cable😀.
The arduino disconnects the main power supply transformer. This little inverter next to the arduino draws less like 0.3 watts so not much. I tried to do this on some attiny but failed. I think that if I had discovered this thread on the electrode earlier, I would probably have designed it differently, no knobs, just remote control operation and a front like yours, i.e. plexiglass with the width of the display over the entire height of the front panel.
I'm waiting for you to add support for the 2nd encoder in the code and as far as I'm concerned that will be all I expect from a radio😀.

Thanks for the hint
The problem will be with the equalizer at the FLAC decoder does not work out processing and cuts very much can be done in two ways as it detects the waveform only 8 point equalizer works or turn off the eq completely.

@wieh76 Isn't it simpler to power the ESP from a small inverter it needs only 150mA with the OLED and then control yourself in standby mode with this big relay and trafo to the amplifier ?
You are quite rid of the little Atmel which does the same thing as the EPS in sleep mode.

Wait, I'm looking and looking...what is on that big board with that huge heatsink ? The power supply for the ESP ? Only ?

@robgold you guessed it😀. That transformer and heatsink only look huge in the photo. The trafo is small just compare to the nano. The heatsink fact I could have trimmed a bit. In my trial current measurements, the meter showed a current of 0.2 to 0.5A depending on how much information is shown on the display, so I was worried that this converter would not be able to handle it. Besides, at the time, this was the only way I could implement on/off, because I can program myself a flashing diode😀

with this transformer and heatsink you could probably make a nice amplifier with 20W that would make sense

@irysbox no exaggeration the trafo is 10W. Apart from that, the topic is already out of date😀. After a late night discussion with robgold this remains:



I have also added an external wi-fi antenna socket as the range halves when the case is closed.
The ESP with the antenna socket is already flying from China🙂 .

I will add updated instructions on how to upload everything from scratch.

Maybe someone will find it useful.

Regards ....

Fellow @bolszoy I have described the installation procedure from scratch below

https://www.elektroda.pl/rtvforum/topic4041603-1500.html#21748612

These libraries given there are for the Robgold software

If you want to load the Mayster software you also need to have the libraries listed above and for this you need 3 libraries

Adafruit BusIO by Adafruit 1.17.4
Adafruit GFX Library by Adafruit 1.12.3
Arduinojson by Benoit Blanchon. 7.4.2

You have it all nicely in the pdf manual what I attached above.

Greetings....
