Internet radio and audio file player on ESP32-S3

Completely redesigned analyser and Equalizer 16 applied
ESP-ADF shows a better way
The best solution for the ESP32-S3:
IIR biquad
fixed-point Q31
16 bands
±16 dB
Check how FLAC and AAC work I look forward to your suggestions.

This kind of error:

I have the same

I can't compile any version either.
I am now focusing on the V2 version and I get this message all the time:

What can I do with this to get it to compile properly?

>>21785356 Writing v2 you compile an old version of the Major, my ?

I will send you a video of how it works now;

The spectrum analyser works "sluggishly". Maybe it should be scaled up to a logarithmic scale? One more thing, volume with "digital" regulation. I would add a mechanised potentiometer control (with drive). The equipment would benefit a bit from this. I'm reading the development of the topic, and so I'm slowly trying to get it up and running. I have everything in place, lack of the urge unfortunately....

He is already rather logarithmic.

Volume control via the PCM1502 is not sufficient?

@simw Such a rotating "scoop" would be cooler.

But for this encoder you can get yourself a branch
I don't quite understand why there is still a motor-controlled potentiometer there, but who can forbid a rich man

ArturAVS wrote:

In my opinion, the power of the MCU is already lacking. So "by eye" it's about 15fps.
With the load of this MCU, that's still not bad.

Design of the device is an important issue

And the encoder with the big knob, isn't that the "design"?

Perhaps I have expressed myself badly. I will elaborate in that case:
Design and operation of the device.

On which standard ?
On Flac does it slow down a lot?
On normal ?
You need to work on the dynamics on Flac .Write how the sound on Flac strongly clips On equalizer 16 and how on 3 switching on and off eqalizer 000 3x0 switches types ęq

I'm downloading the v2 version from the link on the first page which I think is the Majatra version.

I download the v2 version from the link on the first page which is probably the Majatra version.

This is a very outdated version, the author himself no longer supports it, he now has V3 with a colour LCD like this.



And Robgold's version on a mono OLED display such a version.



Virtually everything but the ESP has changed since the V2 version.

Greetings ...

>>21785650 To compile such an old version you must (preferably under Platformio) create a project into which you download all the old libraries from that time including ESP core and Audio. Otherwise nothing will work. The audio library is in constant development and a few things have changed in it (just how the stream information is passed on) so it won't work with the latest libraries.

Added after 1 [hour] 23 [minutes]:

@ArturAVS I read your message and I don't believe it....really you would want to go back to an "analog" knob in a digital device and pull that signal all over the cabinet ? Well no....really not The encoder works fine and if you miss the resolution (which will happen if you integrate an amp) there is an option in the Evo to switch from 0-21 to 0-42 scale - should help.

The one encoder has an "all in one" option that is volume control, station list, bank switching and power off/on. I don't think I can fit any more in there.
Of course, there is the option of adding a DAC and amplifier in one (something from the TI stable), in which case "volume" control can be delegated to the amplifier.

A knob controlled by a motor is good for my grandfather's Schneider tower from 85, that's where I wanted the radio to end up, but those were the times of the rightful past, for new projects, especially digital, it makes no sense, except visually.
I have such a knob in my stereo, but it's always analogue crackles, the only plus is a smooth range of changes, but in the modern world nothing is done on potentiometers, everything is rather encoders, remote controls. I'm talking about home equipment here.

Yes. But only spinning, Pressing the encoder for the weight of this radio without holding it down is impossible.

Etam. I have a Denon amp a few years old and the knob is motor driven.

>>21785842 Stick it as "legs" with rubber bumpers from Casto or LM. It works brilliantly, I have it on a metal Panasonic radio housing and nothing slips.

And as for the "motorised knob", if you have everything analogue in this amplifier and maybe one input as digital, then 90% of the signals fly analogue. It is natural to use a potentiometer because there would be no way to give the user information about the volume level without a display and here the position of the knob gives such information.

You can always read the potentiometer on the ADC and spin the branch with the remote control.

Hello. tell me how to disable the RGB diode in ESP32-S3 radio version v3.19.48? It is very disturbing.

There is a 0 Ohm resistor above the diode you need to remove it, on some PCBs from ESP it is signed as RGB

Greetings ...

In terms of the RGB diode, there are also sometimes jumpers brazenly soldered, and it also happened that the pads were connected by a micro-path and you have to use a scalpel and make a cut.

Hello, as I am getting enquiries about a PCB for a Majster v3 radio with colour LCD.

I am posting the project files, pdf file for thermal transfer, and gerber files for china production.

I have in mind this project and this soft

https://github.com/sarunia/ESP32_internet_radio_v3

The pins on the PCB coincide with the declarations in the script.




Board prepared for ready-to-use goldpin modules




Brief description of the JST connectors or LCD with pin descriptions under a dedicated LCD - 3.5 inch and 4 inch of this type works.




The second JST connector called LCD SD is used to use the SD card module mounted on the display. Simply connect.

There are different versions of the display - the one shown at the top has no resistors at the SD card pins so will work fine.




In the case of those at the top, the resistors at the SD card slot must be removed for the reader to work. Depends on the type of display, need to compare.

Gerber loads correctly on the JLCPCB website, I didn't order these boards, the design checked works for me - I prototyped using thermal transfer.



For the thermal transfer, it is necessary to make the jumpers marked in the view below.



When ordered from china, the jumpers are made on the outer layer.

In the project I used a cheap PAM8403 stereo amplifier, it can be unassembled and receive the signal directly from the chinch sockets, however if someone would like to make a radio for themselves, e.g. for the kitchen, such an amplifier will be enough to drive two small speakers.

The uSD card module is designed under the ESP module, it is best to buy a module with unsoldered pins, in the standard they give a length of 12mm - I suggest to buy a longer one, i.e. 18mm available at auctions, then the ESP module will be higher above the board and the uSD card module beautifully fits under the ESP module.

And the issue of the antenna - some people wrote that the antenna should be designed differently, however, in my case, such solutions work and the radios play, if someone will be strongly disturbed by this on sale ESP32 S3 modules with an antenna socket - you can buy such a module and the antenna for this and either glue further on the antenna board or using the socket to expose outside the antenna screwed under the SMA socket.

So much for design issues.

Regards

Well the finished looks like this





Greetings ....

>>21785977 >>21785967 Actually. I cut the path between the RGB and the resistor with the end of a knife. Thanks for the hint as it wk.... me.

I have made a second menu, this time for the audio file player. In the settings, there are options to toggle the display of the time of a song from the beginning or from the end (I'm currently practising on MP3 files) and to enable/disable random playback of files from the current folder. I calculate the duration of an MP3 track with a fixed bitrate based on its size in bytes and its bitrate, which is the number of bits played per second. I first convert the file size from bytes to bits (multiplying by 8) and then divide this value by the bitrate in bits per second. The result of this operation gives the total duration of the song in seconds. The time counting code still needs to be refined, because some mp3s count incorrectly, I will collect the time for flac files using a different method, because the audio library returns the number of seconds for the loaded file.
Below are screenshots of this menu in action, the code is available at a known location.

>>21785977 >>21785967 You can also disable RGB on the radio by adding the following code:


//NP
#define RGB_PWR 48 //Set RGB LED pin on ESP32 S3, other pin set.
//NP

void setup() {
//NP
pinMode(RGB_PWR , OUTPUT); //Set pin to output
//NP
}
void loop() {
//NP
#ifdef RGB_BUILTIN
digitalWrite(RGB_BUILTIN, LOW); // Turn off the RGB LED
#endif
//NP
}

They most likely have a variable (dynamic) bitrate.
