Displaying the values on the OLED from the ADC also works just fine.

How did you enable the ADC reading on the OLED ?

The board in the Sony has a rather complicated shape, lots of milling for the mounts and on top of that it is very large. I did a quick count of about $65. Quite a lot, the one that is after desoldering does its job quite well. I think for 1-2pcs it's not worth redrawing it.

Sometimes at weekends JLCPCB have a promotion and a 10cm x 20cm board was something slightly over $20 for 5pcs and that's an acceptable price in my opinion.

As for redrawing and sizing it goes quite smoothly for me. So you could give it a try.

Under the IP/ADC tab you have Debug on/off. As you click, it turns on the ADC reading mode on the display. The idea was to not have to have a computer connected to calibrate the keyboard.

@robgold would you add to the config the possibility to put the display into setPowerSave() mode ? E.g. at least <selectem> after 120s, 180s, 240s, off ?

@robgold in the Arduino folder is still bin version 53

I soldered everything off the board from Sony, added new switches, resistors. In adc read mode I have the values (two coincide) but after writing them the keyboard does not work properly. Most of the buttons don't trigger at all, some don't trigger what they should.
.

When I have a moment, I will add such a PowerSave mode. Especially since this OLED 3.12 is terribly chopping the inverter on the audio channel. Listening quietly at night, you can hear this "hum".

@gabar5 you must have something badly soldered, because it works very well with me. The ladder was chosen so that just none of the values in the matrix overlap.

Based on @DJCheester's graber I made tiles in china, they came out pretty cool.

Send it I'll run it 😀

And in the meantime I made a PCB for my keyboard

The darker one is the unsoldered original one and the lighter one is my creation.

.

When there's a moment again I'll solder the keyboard as needed 😀.

I also confirm the ADC on the OLED works.
So now I'm thinking that the key reception could look like that ESP takes three ADC values and averages and then checks with the declaration. I think there would be less false keys. Because sometimes something will pop up a completely different value and then the good values already go.

I will only suggest to the author that if he is bored he can also introduce an option in the settings with learning any remote control.
So, for example, selecting a given function - reading via IR a button from the remote control - and writing it down.
And then there is no need to "remember" specific numbers of the remote control manufacturer or to enter something "backwards" to the radio. .
If there has already been this suggestion then I apologise - I've only read through the thread once so far. I also noticed that in the audio (radio) library itself there is a letter swap for diacritical letters - unfortunately to German and only with C3. As usual, the Poles must have more options (C3, C4, C5), which translates into a bit more complicated code than the one inside the library. .

For my part, I would like to add that I am building my own radio on the basis of this thread (and the knowledge provided by its two authors) - but I am trying to get to know the libraries used in more detail, and besides, I am doing it on a casual basis, so it takes me a while. Among other things, I found that it is possible, for example, to "extract" directly from the audio library separately the signal strength of the L and P channels even before they are combined, so you don't have to divide and shift the bits later.
The option (in the examples) to read the time is also interesting. Of course, it is worth correcting from EN to PL in the code. Or the "karaoke" function - but for this, the mp3 peaks need to be adequately "described".

But back on topic thanks to the authors for sharing their knowledge. I will not fail to draw on it to the full .

I love this feature - especially on weekend evenings when it's even after midnight.... Then I listen to MiniWebRadio on the Wolle version and those hours read reminds me to go to bed already..... "precisely" .

and learning the remote control - you can probably borrow from YoRadio - it is beautifully solved.

@marek003
- Due to the simplicity of the web server (it's just plain Async without websockets) No plans to add pilot learning functionality at the moment. You enter the codes once and that's it. I don't think anyone orders a new remote control every day ? Besides, I have a lot of other activities and work activities lately. We will slow down a bit for the summer with these updates.

- Polish diacritical marks are substituted in the program code not in the library and we use both C2, C3, C4 and C5. You have the whole set with Polish "tails".

- The radio has a function implemented to read the time in Polish. The function with English is left in the program code but is not used. Perhaps I will add it in the radio configuration in the future.

I have uploaded Evo3.17.60 to GitHub Link .
- has an added PowerSave function (turning off the display) after a stored time. The display switches off after the declared time, wakes up when the remote is pressed or the encoder is turned. If for some reason the stream stops playing, the display wakes up, starts displaying "no audio stream" and does not enter the Power Save trim.

- in the SD card explorer, I have added a file EDIT option.

- I improved the code (mainly comments) in such a way that now, if one really wants to, one only has to search in the ino or main.cpp file for the text "SD." replace with "SPIFFS." and add " #include "SPIFFS.h" " and one can get rid of the SD card. There is one exception where you have to uncomment the SPIFSS memory declarations but by doing a "search and replace" you will notice this feature. This will ensure that the radio will have SPIFSS memory instead of SD card from now on. Of course, you have to upload the icon files and the remote.txt file for yourself via www.

Bank Editor Link .
I have made a simple bank editor. The editor allows you to download a given bank directly from GitHub, change what you need, change the order of stations and if you give it an IP number it will even automatically send us the content of our changes to the SD card of the radio There is also an option to play a given link before you load it. Pressing Play will play it on the radio using the radio's integrated playback function from the link provided by the web server.
The editor is nothing more than a clever html file with a few scripts. It needs to be downloaded to disk because GitHub will not open the HTML like a browser only displays the source.

NOTE:
This is a demo version, it has completely no security mechanisms. If you type "Ala has a cat" in the name of the stream this will also be loaded on the SD card. The editor overwrites the current files of the Bank in question on the radio. Once the new content has been uploaded, simply reload the respective Memory Bank on the radio.

.

As part of the Christmas 'bunny', I have uploaded this week's update 3.17.65 to your GitHub.

- I added one menu where all options are now present
- there is a new (v1.05) banks editor, it pulls banks from a txt file, github or from the radio and detects the IP or hostname of the radio itself (you have to upload the editor.html file to the SD card via web or external reader)
- I added mDNS, the radio now reports itself on the network as hostname: esp32radio i.e. http://esp32radio.local This works minimally slower than by IP, but if someone has DHCP, there is no need to check the IP at startup.

The development of this project is commendable. Have any of you tried combining radio management with Home Assistant? It would be nice how the radio would turn on initiated by a trigger e.g. presence in the room.

Robgold - great job! The radio is world league ! Thanks for the hour and turning off the OLED - it gets quiet and audiophile. I'm writing and listening to Radio Paradise Main Mix.... and it just says it's 11 o'clock Oh and surprise surprise after anon reset and play on.... I still have a spider without coupling cones.... it's probably their fault.

Merry Christmas to all !

Yoradio has MQTT - have you tried it ? Does it have any practical use ?

@wirbud E.g. such that the radio turns on when I'm in the studio and off when I leave. Yes I know I can do it myself, walk up and turn it on/off, but if something can do "itself" then even better .
Yoradio I haven't tested yet, I'll have a look.
I see it even has a custom component for HACS, so it's prepared under HA.

Indeed - great ! And how should your presence be detected - a presence detector ? (because Ikea's PIR probably won't work because how is it supposed to recognise that you went out or you are still there but you don't move.... A bit off topic but I'm playing around with HA now and watering the plants as they dry of course. Maybe I'll radio them on occasion when I am or when I'm away. Thanks

Yes, an occupancy sensor would be the best solution, you can do it on a pir with a long delay to fade motion detection, but it won't work quite right, I have an auxiliary (night) light in the kitchen done this way, one of the first automations, enough for me, but not crazy.
Trigger could be e.g. computer on, light, anything connected to HA

Hello, I am also considering the option of active radio mode, i.e. radio on, and a sleep mode on the screen, some graphics for a while and then blanking, triggered by the state on the selected pin, but I am not as skilled in writing code to do this myself.

Greetings ...

@DJCheester I just tried to do something like this today, I added an extra microswitch pullup to the 2nd GPIO pin, a few lines of code and with this switch I turn the radio on and off. Testing for now. If that's something you wanted I'll add the code....

Hi the code can you please provide or write the changes as I will be distosing to my project anyway and the switch will not quite work like that. Regards...

I don't know if anyone will find it useful to switch on and off using the microswitch, but I missed it and I've put a few lines together in the dirt.

Ps. I am not a programmer - code to be improved by more experienced people. But it works .

@wirbud The reset you have on the Paradise radio (presumably FLAC) is due to the Audio library. It most often "rash" when it should switch to an mp3 stream then switch back to a FLAC stream. Although this is not a common occurrence. It happened to me once in the previous month. On mp3 stations it doesn't have this problem.

As far as automation is concerned, it is enough to control a simple "relay" type module, which will switch on your power supply (USB charger) to the radio. The whole thing, after all, wakes up about 2 seconds after which it plays.

@Lechuuu the code is OK. However, it's still such a "half dream". ESP is asleep but PCM is powered. Correctly everything should be cut off by a transistor and only then ESP asleep. At the moment it's just an illusory feeling of being switched off but in fact not much is switched off. Additionally the ESP should wake up to the remote control button, check if it was the POWER button if so then "get up" if not then continue to stay in sleep mode. This is how I would see it. We will probably add such full functionality over time. Without remote control operation it's all the same to me if I get up from the couch and have to snap the switch or the button.

Welcome .

Today, out of an excess of free time after Christmas, I got the new radio up and running

You can give it the name UNO (although the first one is not)

I used the following ESP32 module for it

.

Adding to this is my second PCB project based on the sandwich.

.
.
.
.

I "slimmed down" the radio - missing the connector for the encoder, the connector for the keyboard, and the PAM8403 power amplifier (2x3W).

I hooked it up to my tube radio and it plays nicely.

Note at the beginning my SD card didn't work - it turned out that on the Chinese module the GPIO47 and 48 pins are swapped, physically they are reversed, I suggested the description when designing the board and now I have to swap in the code to make it work But this is not a problem.

I would add that this larger display doesn't chop as much on the audio lines .

Regards ....

Hi. I have also put together a yoradio project but have noticed a problem with the stream frequently trimming. I have a esp32 wroom 30 pin dac pcm5102 board, 2 x encoder and ssd1322 display. Power supply from a 33w charger. Wifi perfect, shows 22dBm rssi. Anyone have any ideas on this?

For this project you must have an esp32s3.

@hetm4n In this thread, there is a slight scrolling topic of parceling a library related to packet buffer size, or something similar. To my eye, that's the problem with you, so you'd have to go through that thread page by page, because the reference to parceling that lib is there several times.
(I can't help you exactly, as I haven't put it together myself yet, but loosely reading through this thread, I picked up that it absolutely has to be done to improve stability)

Welcome.

I have a question .
I have been changing the look for a while and found that I wanted the day of the week.
After adding it, the day appears to me but unfortunately not in the format I would like.
I got it in the format of the number Saturday is 6. How do I change it to display for example: "Mon"

.

Thanks.

@nouki you have to build yourself a "case" for this. You have it in displayMode=1 (clock)

code snippet:

.

Unfortunately I do not use this design but another. In addition, I have not written anything for a long time .

Thanks

Welcome,

I have uploaded on GitHub the update to 3.17.77 , ->: Link .

What's new in 3.17.77 ?
- I have changed a bit the layout of the radio's website
- We have WebSockets, i.e. station data, volume and the added station string is transmitted in real time (e.g. by turning the encoder on the radio, the volume on the page will also change)
- In the configuration there is now an option to extend the VOLUME range from 21 to 42. This is useful if someone wants to build the radio module together with the amplifier module.
- I have added auto creation of the config file. If the radio does not find the config.txt file, it will create it automatically on first start-up
- The code is written so that by replacing the SD entry. (SD dot) to SPIFFS. (SPIFFS dot) it is possible to use the SPIFFS memory instead of the SD card. Then you have to use the website to load the files from the SD card content directory (especially editor.html)
- is MDNS, the radio reports itself on the network as host: http://esp32radio.local/ regardless of IP.

Have fun testing.

.

@robgold thanks for the new version

Observations from the new version (maybe only for me)
- in Configuration on the page is Max Volume Extended [0] range 1-21 or [1] range 1-42, in the selection On/Off (for consistency should be Max Volume Extended [OFF] range 1-21 or [ON] range 1-42)
- volume range change (works after radio restart), is this the way it should be?
- if a station broadcasts a title with Polish characters, then after switching to this station there is no title in the window on the page, when switching to another station, the window does not refresh, you have to refresh the page. You have removed the processText for decoding Polish characters, if it is disabled, it displays Polish characters on the website, but does not display them on the radio.
