Internet radio and audio file player on ESP32-S3

Hallo zusammen, ich bin sehr begeistert und ein Neuling im Thema ESP32. Habe bereits 2 x CYD Cheap Yellow Display erfolgreich eingerichtet und mit Audiokarte erweitert.

Ich habe ein weiteres ESP32 S3 mit einem GPIO Extansion Board und einiges anschließen können.

Habe allerdings nur ein TFT 2.25" 284x76 ST7789 P3 Farb Display hier.

Dann Liegt hier noch der PCM5102 I2S IIS DAC

2 x KY-040 Drehgeber Rotary Encoder

Und noch ein 38 KHZ Infrarot-Empfangsmodul

Aurduino IDE und alte Version Aurduino 1.8.19 etc habe ich mich sehr viel eingelesen aber leider keinen Erfolg gehabt. Immer nur Fehler bis ich die Geduld verloren habe.

Habe jetzt über Github ESP32_radio_evo3-main zip geladen und aus den Build Ordnern ein full Image mit ESPConnect (Webflasher) eingespielt.

Der ESP32 S3 startet. Habe Wifi AP bereits eingerichtet. Ich komme auf die Weboberfläche und kann in die Einstellungen gehen.

Ich habe leider keine Fertige PCB und muss meine Hardware irgendwie verbinden. Leider finde ich keinen Schaltplan (Schematic) wie es ohne diese PCB funktioniert.

Was mich auch noch stört ist das diese helle RGB LED sehr weis leuchtet - die macht mich beim arbeiten blind

Ich hoffe ihr könnt mir helfen. Und es ist nicht schlimm das ich in Deutsch schreibe.

Habe hier schon sehr viele Seiten durchgelesen.

Hello everyone. As I'm a layman, but I like to play around, and after reading I see it's fun and even inexpensive, I have a big request. If someone who knows a bit about this, and I see you are quite good at it, could help me with the hardware for this game. I know that you need an ESP32, but the choice on the Polish market is large, and on the Chinese market infinite. I'd like to buy a good one, reasonably up-to-date and, most importantly, one for which there is freely available software and expert help, and it's not about the £30 cheaper.
ESP32, from what I can see, there are with built-in antennas and with external antennas, newer ones on USB-C, WROOM-32U, WROOM-32, WROOM-32 38-pin with CP2102 USB-C chip, WROOM-32 30-pin with CP2102 USB-C chip. There's a whole bunch of these and I'm completely lost. Maybe also some larger LCD, as I'm getting on in years and have poor eyesight.

Hello, my eyesight is already poor too

What you need for this fun depending on the version of the radio you want to build.

Here are two versions currently being developed by colleague MajstraXXL with a colour LCD display such as the one below.



And a second version by colleague Robgold (with modifications by colleague ejcon) with a monochrome OLED display such as below



Both projects differ in the type of display and in the different GPIO connections

You need to decide which one you want to build.

And as for the parts as above colleagues wrote you need an ESP32S3 Devkit and a version of the N16R8

I recently bought from this link

https://pl.aliexpress.com/item/1005009212121307.html

This is the version with an antenna socket but without soldering a small jumper at the socket it works with a PCB mounted antenna

For this you need a PCM5102A DAC like this one

https://pl.aliexpress.com/item/1005008077598378.html

A microSD or SD card module, the one I use works but you need to remember to supply it with 3.3v and not 5v

https://pl.aliexpress.com/item/1005005302035188.html

And you need a display to run the radio

For the OLED version, you can use the 3.12" available in four colours

https://pl.aliexpress.com/item/1005007610590861.html

Or the more expensive larger 5.5 inch

https://pl.aliexpress.com/item/1005006150123067.html

For the LCD version, a 3.5" display can be used

https://pl.aliexpress.com/item/1005001998578860.html

Variant preferably IPS no touch

Or the larger version 4 whole also recommended IPS.

https://pl.aliexpress.com/item/1005006287973267.html

This is enough to run the radio the schematics are respectively on the github of a colleague Major

https://github.com/sarunia/ESP32_internet_radio_v3

And of colleague Robgold

https://github.com/dzikakuna/ESP32_radio_evo3/tree/main

The difference between IPS and TN LCDs is that the viewing angle of an IPS is much greater so for a radio it's worth buying one.

Below a TN LCD display at an angle



And below an IPS at roughly the same angle



In the case of this display, it has an SD card reader soldered on the back and can be used instead of a microUSB reader

As far as I know on some versions of the display there are resistors pulling up the reader lines to the power supply you have to remove them for the reader to work, but on my IPS there are no longer these resistors so it should work when properly connected, I haven't checked.

One last thing on colleague Robgold's github is the PCB design and gerber files for manufacturing in China, this version of the PCB contains SMD components.

I a few posts above shared the file Termotransfery.zip there are gerber files for production or thermotransfer files for both versions of the radio.

These PCBs are on Goldpin plug-in modules without SMD components everything is rewired.

I have made available 4 versions of PCBs under LCD by Majstra under OLED by Robgold, version with one and two encoders and version under other ESP32S3 Uno

The PCB design for the LCD includes an additional JST 4pin connector to connect with it to the SD card reader on the LCD.

On my PCB versions I added a PAM8403 power amplifier, so the project assumes connecting speakers up to 3W and building a radio, e.g. a kitchen radio without using an additional external amplifier

Such a module is under this link

https://pl.aliexpress.com/item/1005009290579985.html

That would be it, my colleague from Germany will also find this knowledge useful to start with, from what I have seen the display my colleague has a different one should be supplied with any of the above mentioned for the project.

Added after 16 [minutes]:

The encoders the colleague has good, the transmitter also, the display should be bought about the PCB and schematics I wrote above.
Remember to configure the encoder correctly with the patterns (solder fields on the underside of the PCB) and if you buy an OLED display, the resistor configuration must also be correct. If you want the RGB LED to be off, remove the resistor marked RGB on the ESP board. I have a TSOP31238 in my projects and I think it works best without interference from the inverters of fluorescent lamps etc. I therefore recommend the TSOP.

Regards...

>>21798125 The @robgold version works perfectly. The app and configuration pages work perfekt. And, as I say, being 67 springs to mind. I mastered quickly and it works. On the side, not the side, in the photo is the FM wireframe I used. I have now bought the 3.5" display I will be testing the second version from @MAJSTER XXL. My ESP32 S3 was not getting up, after powering down. I first pulled GPIO0 up to 3.3 volts. It worked. But I did a second trick and soldered a capacitor at BOOT. It also works.

>>21798125 Thank you for your help, time and specific guidance. The information is very useful and I will certainly make full use of it as I move forward with the project.

If you have any questions 😀
I'm sure someone will help.

When starting up the radio this information will also come in handy

OLED display configuration - solder these resistors so that R5 and R8 are soldered and R6 and R7 are left free



For the 5.5" OLED display, remove the resistor marked P8080



Next, for the PCM5102A converter, solder the jumpers on the underside of the PCB as shown in the image below



And for my versions of the Robgold boards for the OLED display the pinology of the 3.12 inch OLED display



View of the board as seen from the components side version with one encoder, version with two encoders the connection of this socket is identical.

In the display the 2x8pin goldpins are respectively signed in the same order.



Regards...

Thanks for the explanation, it's certainly useful information, like the display and PCM...nakonfigurovacz

I have ordered, and God's will be done
https://pl.aliexpress.com/item/10050092121213...ain.5.4c521c24NFp8iE&gatewayAdapt=glo2pol
However, I have decided on another 2.8 inch screen
https://pl.aliexpress.com/item/10050097613839...in.10.4c521c24NFp8iE&gatewayAdapt=glo2pol
Plus the indicated DAC and the indicated two encoders, because it was cheaper that way, and a set of cables with terminals. I will buy the rest of the components already in Polish shops, because the orders from China only had delivery at the end of February. I am still thinking of the PAM8403 amplifier , prototype boards, SD card slot if the one from the screen proves unsuitable, goldpin sockets and plugs and the 830 field contact board in white.

If you ordered with a resolution of 320x240 that's wrong, for this radio it has to be 320x480 I have provided links 3.5 and 4 inches.

Regards...

Hi colleagues.
Has anyone bude zamavjacz PCBs from China from JLCPBL, will they be made by thermotransfer?
As per the proposal published by DJCheester.?
I would be interested in two boards each of these versions:
2. A board under Robgold v3 evo software (up to the latest software version 3.19.53 with two encoders)
3. Tile under the Majstra v3 Color LCD software - available from the latest version

Thank you for your help.

>>21800060 I did a quick turnaround. And the one from the link I understand is ok
https://pl.aliexpress.com/item/10050019985788...632327%21%211%210%21&gatewayAdapt=glo2pol

Yes this IPS 3.5 inch no touch. The reader is without resistors so it should also work hello....

>>21800080 I've learnt a lesson not to be canny, but to listen to what wiser people say.

And there right away smarter, just a year back I already found this topic and I was pestering everyone then what to do 😀

Greetings...

>>21800284 Tell me more please, the order of connecting the pins of the various components, screen, encoder and DAC to the ESP32 S3, and where do you guys get this information from. Then, how to swap the remote control in the project https://github.com/sarunia/ESP32_internet_radio_v3
for the encoder. In this version, which is really cool, you can see that the developer has put a lot of work in, but I'm still wondering what and where to connect to the ESP32 S3.
I know there is a program where you add the appropriate components, but as far as I can see it supports the old ESP32. https://e2002.github.io/docs/myoptions-generator.html
And that is the whole secret of this device, connecting all the components correctly. The way I see it at the moment, the design is super clear and easy to understand, switch this, download that, paste here, change there, set up like this. It's all clear and after studying it I've already caught it. The creator literally leads by the hand, however, I am missing information on how we identify the pins on the ESP32 S3 and how to swap the remote control for an encoder, and if there is a similar program for the ESP32 S3 that creates such a batch file.

Hello here is the pinout of the ESP32 S3 module

https://mischianti.org/esp32-s3-devkitc-1-high-resolution-pinout-and-specs/

On the github of colleagues there are diagrams where the GPIO connection between modules is described

If you have an Arduino IDE environment run the sketch with the ino extension this is the source code and there is also the GPIO pins of the individual signals declared at the beginning, the signal descriptions are on the modules so you just need to connect this.

Or best for me use the schematics.

Alternatively, if you have a little experience, you can order a ready-made PCB from China and solder the components and modules.

Encoders are in case of Robgold software 1 or 2 it is set in code, with changes in code you need compilation and for that you need a series of actions with libraries to make it work, of course you can follow the instruction what I did some time ago to play it one by one. But if you don't want to do that you can use the compiled ready batch and flash download tools from espressif and with this program upload the software to the new ESP.

The issue of the remote control is created by swapping the codes in the text file you win this to the card. The files can also be found on Robgold's github.

Added after 3 [minutes]:

In the case of Majster's colleague's software, the pilot codes are declared in the sketch, i.e. the source code, you then need the entire Arduino environment with the new Core 3.3.3 and all libraries, a description of how to install this one by one is on Majster's github.

Regards...

Added after 38 [minutes]:

For Robgold's colleague's software you have these declarations in the code





For OLED 2.08 display, OLED RESET pin 41 required





If you are building with two encoders then you connect the second encoder to the





As for the remote control button declarations, you need to SD card or SPIFFS memory (depending on how you defined it in the code - the default is to SD card)
upload a remote.txt file and inside it this structure



Instead of the code 0x006A you give your own, how to read it, after uploading and starting the radio you need to start COM transmission (serial monitor) and there, when you press the buttons of your remote control (remote control must be of NEC standard), the command will appear - then enter it into the txt file.

After supplementing the remote.txt file with your commands read from the serial monitor, save the changes to the memory card or via www to SPIFFS and after a reset of the radio, the remote control should now work properly.

This is the manual for the OLED radio version of colleague Robgold.

For the version of the radio with a colour LCD display there are other connections look for such lines in the Majster code by analogy.

Regards ....

I have a question for @robgold @Majster XXL about banks. Wouldn't it be better to make a common bank with identical data? It would be simpler. You could make money from the station databases. They could come forward from radio themselves to add their stations. Or those who listen to radio. Collaboration doesn't hurt. (I only do in my spare moments when the headache stops.)

Hi

I have a question. When compiling the code under the ILI9844 display, it threw me an error:

AI suggested to remove the line:

As I did this the compilation ran successfully. Will this affect the correct operation of the device?

@bernix update your Arduino IDE to the latest version, I use the latest versions of all libraries and the esp32 board manager.

And would there be a chance to share the bin file of your version of the radio. I'm going a bit on the easy side. I have ordered PCBs of your design so everything should fit perfectly.

Everything also laughs on Arduino 2.1.1 under Windows7 64bit.

You have version 1.8.19, which was the last version under Windows 32bit and therefore the core itself is not the latest, probably 2.0.17 as far as I remember

Since the third version of core the compilation tools are already 64bit.

You need to update your software to at least 2.1.1 Arduino
If you have Win11 then win the latest as the author advises.

@bernix

Currently not, because the remote codes are sewn into the main program code (in the so-called arduino sketch- .ino file) and in this file you have to set your own button code assignments for your remote read after uploading the compiled program and reading the remote codes on the serial terminal in the Arduino IDE.

MAJSTER you can send him any compiled binary, he uploads it and reads the codes through the serial and gives it to him again to compile with the correct ones.

Regards ...

This still does not save you from having to compile the program code yourself without errors and load it into the ESP32.

But if, say, I send him a binary and he downloads it (it is clear that the remote control will not work for him), but the serial monitor catches and writes down the codes of his remote control (assuming he has the NEC standard) and I send him these codes, I can compile a second binary with his codes and then send him a second binary and the remote control will work for him.

Regards ...

Added after 41 [seconds]:

I will load the binaries with the flash downloader from espressif

If a colleague has the time and inclination for such a feat, then sure. I assume, however, to do it myself, there is already a lot of advice and instructions, on my github to v3 is very detailed.

It is known better to have a compiler at home at least for newer versions from the author

But if he fires it up once, it will encourage him to do more work

I too was only supposed to make this radio and now I have more than one, I am testing softy's and fiercely sitting on my Schneider version

Greetings ...

>>21802224
Ok . I take up the gauntlet

>>21801120 If I'm not mistaken the format of the memory banks is still the same so when you upload them to the memory card/internal memory (evo) you have the same banks permanently.

>>21802224 I've ordered everything out of the box, i.e. everything from the links provided plus a dozen extras, and I'll still house that OLED screen. The cost is such that I could buy a ready-made radio in a shop, but I do not listen to the radio, and so at least I will have a lot of fun and joy that I put everything together myself. It probably won't be as fun and easy as yours, because from what I've read, you guys are in the electronics business, but I'm stubborn and inquisitive.

Hello, as a small error crept into the gerber files, I am adding a corrected version.

The error is in the descriptive layer (the paths are as they were before) so the thermotransfers are fine

On the already ordered boards there will be a bit of chaos on the descriptive mask.
I have only now checked this on the JLCPCB website

The Major and Robgold(2enc) boards will look like this



After improvement, yes




This is what happens when you have too many versions of libraries.

To those who have already ordered, I apologise for misleading you

The Robgold 1-enc version of the board was done before and correctly so the fix only applies to the other two.

Corrected heat transfers attached
