Internet radio and audio file player on ESP32-S3

Hello.
I would like to build a radio according to the EVO3 project. I would like to mount it in the housing of a Diora AS502 radio, such a gift for my Father-in-law.
I have a few questions:
Is there a list available of all the components needed to order and have everything needed to solder into the PCB. I have not found such a list on GitHub.
I would like to omit the encoder from my project and replace it with regular buttons (right, left, enter). Will this be very cumbersome?
I wonder if it would also be possible to assign 8 additional buttons as memory for 16 favourite stations (one button remembers two stations, short press/long press).
I don't have much experience with writing programs unfortunately, but I'm trying to develop

Hello, referring to the above message, the evo3 radio is prepared to work without an encoder, but with the possibility of adding and assigning a keypad.

More about this in a moment, because I myself am preparing a version with a keyboard.

Greetings....

@dawidkosciesza The Evo has built-in keyboard support based on a resistive ladder and ADC. There are plans to replace the ADC with a PCF-based keyboard chip. At the moment, there is no 'Favourite' station option. Perhaps one day I will add it.

You are left with the option to add this piece of code yourself or, alternatively, you can program the 16 favourite stations in a specific way, e.g. in Bank 1:

1 - under 1,
2 - under 2,
...and so on up to 8,
8 - under 8,
and then another 8 as:
11 - 9 station
22 - 10 station
...etc. to
88 - 16 station,

simply the buttons 1-8 from such a tuner can be connected to the numeric keypad code.

Welcome.

For some time now I have been creating another "block" for my Schneider tower. The tower is now about 40 years old, I have renovated this equipment, and added a CD player integrating function and interoperability with the whole set, that is, operation of a common remote control, input selector and recording to cassette from cd.
The equipment has full compatibility.
Especially from here I would like to thank my colleague @gps79 for developing the software for the CD player, if it wasn't for him it wouldn't be compatible with the rest of the set, it was he who wrote the remote control reception in ITT standard and the input selector support.
My warmest greetings to him from this place.
Someday I will describe in detail how we have been struggling with this construction, but I would like to do it right and, as you know, you need time to do it, which is still lacking.



As the equipment is modular I intend to add another block consisting of this radio from the Robgold evo3 version of the coll.

There is already a PCB version without encoders but with keyboard and remote control operation.

PCB for my version of the radio.



The whole thing will be mounted in the tuner like this.



I still don't want to get on with it yet because what I feel like sitting down to make changes to the code Col. Robgold gives a new update and new features (for which I thank him)

Someday, however, the project of a mini Hi-Fi tower from the 1980s in Germany will have to be completed

Greetings ...

Hello, there is no list of components. On the other hand, there are schematics on GitHub and on them it is described what type of display. But you have to read, sometimes several times, because you can actually get lost. Even someone asked about the type of display, if I remember correctly.

DJCheester- Towje solution helped but now I have another error?

I understand that the issue is:



As for the attachment above /file.h/, I don't know by what miracle it attached and how to remove it.

Well I was also wondering why you attached this file.

The question is what windows do you have and is it 32 or 64 bit ?

Greetings ...

Win 11 64 bit.


There is an empty /.ino/ on line 3024, and I think this is about the link. I will try again tomorrow.

If it's blank then nothing is probably about the line above, but the code is good because it compiles at my place.

Looking through the log I am concerned about esp32-x32 it looks like it wants to run on 32bit.

And what version of core do you have ?

Greetings ...

Kitchen 3 something ... I think the latest one is 5.
I'm looking for that link, and will install again. I've reinstalled Arduino and may have knocked out....

I have 3.2.0 installed

Maybe there is a problem here somewhere, because with me on 3.2.0 it compiles correctly.

Maybe try an older core install.

Unless other colleagues have any more insight from the league.

Regards...

Good afternoon. Can such an ESP set with LCD be used to create an internet radio?

I don't see an audio converter here, so it's out.

If anything, it's something like this:

https://pl.aliexpress.com/item/1005008709461693.html

Here's the converter, but you'd have to redo the whole sketch because this LCD has a different resolution and controller.

So ready-made boards that you can upload the software to without changes, I haven't seen.

Greetings...

A DAC can always be added externally. The question of adapting the software remains.
But yoRadio, for example, will go on both boards quoted here.

Of course the pcm can be doped, but I guess the idea is to have everything on one PCB. So it would be better to use the yellow one.

And then there is the issue of resolution and the display driver.

Because the Evo3 is a software for OLED, only the master software could be tried. I prefer to assemble everything myself on the PCB as in the project.

But whatever you prefer...

Greetings....

Take a close look at the yellow one. There's audio on it, only that it's a simple mono amplifier controlled from the ESP's built-in 8-bit DAC. So poorly, and very much so. On top of that, it's a regular ESP32 and not an S3, so there's no PSRAM.

Well, that's a bummer, but thanks for writing.

I still think I should get my PCB made even at a china shop

If necessary, I will make gerberas available for the radio of coll. Majster (LCD) and coll. Robgold (OLED)

If something I will upload in a moment. 5pcs PCB about 25zl with free shipping of course JLCPCB.

Greetings...

The success of the attempt. This is what I wanted to achieve. A very good project.

I would like to thank all the authors who contributed to the Evo3 internet radio project for sharing it as open source.

None of the ESP32 versions have ever had a built-in DAC. A software (PWM) one, is as possible to implement.

PSRAM can be added to any version.

Hello did I miss something, is there already a version of evo3 with spectrum analyser ?

Greetings ...

This does not change the fact that it is implemented programmatically. Typically hardware-based is missing.

@khoam I don't think you put it very precisely in ESP32-S3 you have PDM but no LPF. You have to build that yourself. Ordinary digital output.

Hi, I am new to the topic of internet radio, but after reading your posts I would like to make a version of Evo3 - Robgold for example - myself. And my question: where to start? Probably by ordering components e.g. from Aliexpress and making myself a board from a Chinese? I don't think I will have any problems with the electronics, but I do with the software and the casing. Please tell me how your adventure started and what were your steps, hmm? Is my thinking correct for someone just starting out? Please give some advice, thank you very much in advance and best regards.

Hello I started by buying modules on Ali .... and designing the PCB, as for how to install the Arduino and the needed libraries I recently provided a step by step instruction in pdf. It's in the subject line. On github my colleague Robgold has a gerber for his PCB you can order yourself from a Chinese. From what I remember there are SMD components. If you want, I for the version of colleague Robgold's Evo3 have designed a board on through-hole components and modules.

This is how it presents itself. I already shared the gerber in the topic. But at the moment I have a little modified and if something I will win the gerber for the theme.







Soft of course by a colleague of Robgold.
It can also be done on a contactor but this is an unstable design.

Greetings....

The ESP is on 18mm goldpins and plays fine without an external antenna, these are Gh frequencies not long wave.

2cm from the board is totally sufficient, wi-fi level 5 dashes 😁

I wrote project proven because it works for me.

Greetings....
