Internet radio and audio file player on ESP32-S3

Hi but by default when power is switched on it is on or off, or if it is on where do I declare it in the code to be off when switched on.

Greetings...

If you save in options disabled, it stays that way on startup.
In the code it's probably this function, change it to false.
.

@DJCheester I've introduced a whole configuration mode via the website. Now you can configure whatever you like. These settings are "permanent". They save to the SD card and the radio reads them every time you start it up. Of course, nobody is forbidding anyone from creating their own variations. That's what I make the source code available for.

@robgold will you be releasing any new version in the coming days 😉 ?

@hevet Yes, I made a mode to configure separate VU and scroller refresh times, and the displayMode (radio scroller, clock, fixed 3-lines) from which the radio starts. I've also made the ADC keyboard switching threshold configurations for my own purposes via the web site. I don't know if anyone besides me is still using this.

That's great.

I will be using 😀

Also 16 ADC buttons

I'll be redoing Schneider's retro tuner


Overall this is part of a larger retro set from the 1980s


For this, I reworked the amplifier from another twin model, and refurbished the equipment and retrofitted the CD player in a tape recorder case (drawer)

The whole looks like this.

The kit is designed in such a way that you can stack the blocks on top of each other (via the DCS connector) connecting everything without cables.

I am now planning to continue with this, i.e. to make our internet radio in an analogue radio housing.

The Main PCB will be redesigned.
The keyboard PCB is in the process of being created.

I will also make use of it. For me, a radio without buttons is not a radio, but a boombox (I think that's how it's spelled) - /obviously such a joke/.

@robgold trying to add display mode myself in options. I have it done like other options, everything writes and reads correctly. The problem is that when I change Display mode and save the config, the two modes overlap, I have to refresh the station. How did you solve this?

Welcome,

I have uploaded updates 3.17.52 Link .

New options in the main configuration have arrived:
Display Mode (0-2), 0-Radio scroller, 1-Clock, 2-Three lines without scroll - option in which display mode you want the radio to start up
VU Meter Visible (Mode 0 only) - whether the VU meter should be visible in DisplayMode 0
VU Meter Refresh Time (20-100ms) - VU meter refresh time
Radio Scroller Refresh Time (20-100ms) - time how fast RadioScroller info should be scrolled in DisplayMode 0 mode
ADC Keyboard Enabled - enables the ADC keyboard. Normally this is disabled unless you have a radio implementation in some tuner

.



Additionally, by going to http://NUMER IP RADIA/adc we can configure the switching thresholds for the ADC keypad. By turning the ADC debug ON. We will get the current reading from the ADC on the OLED display. By pressing individual keys on the keyboard, we get the values to be entered into the table. The data will be saved on the SD card.
This is an experimental function, so there is no super description of it yet. The function works ONLY if the ADC keypad is enabled in the CONFIG menu. The photo of the display shows the maximum reading because I have nothing connected to the ADC input on this radio.

>>21511951 And what function on the remote control implements this ? Only without a peek into the code on Githube. Figure it out yourself .

@robgold probably simulating the OK button 😁

Missed but you are very close. OK yes it will call what you want but unnecessarily it will still want to reconnect the stream.

Added after 6 [minutes]: .

By the way I don't think anyone has used an encoder since the pilot was added. I do not know if you know, but until the release of this version in encoder mode volume control - click to display the station list, long hold - menu bank, it was not possible to switch the bank properly

@robgold cmdSrc button?

rcCmdBack .

@robgold thanks .

As far as I can see, the screen doesn't brighten when I switch stations left - right. Is that supposed to be the case?

Yes, if you know what you're doing then why brighten it up. This is due to the rebuilt dimmer function. Probably in the next version it will no longer be restricted to the SSD1322 display only.
If you miss this, insert -> displayDimmer(0) into the station change function;

Ok, I thought there was an error, thanks for the clarification.

In this version, clicking on the station name in the browser should do what?
With me, only the volume level is displayed, but the expected switchover to the clicked channel does not take place.

I have a St-s120 tuner I would like to use the front panel buttons, but don't know how to go about it. I've looked through historical posts, but my lack of knowledge and experience means I don't know how to go about it. What, where and how to connect to be able to read the values on pin 9?

@simw should change the station to the one you clicked on. It works for me without a problem.
Go into configurations and click "Update" because compared to the old version a few variables have appeared and maybe something is not reading correctly.
I will maybe upload 3.17.53 later today as I found a few minor bugs mainly with encoder handling.

@gabar5 I'm planning to start a separate project on GitHub and maybe I'll make a separate post here on Elektroda about converting such a Sony to internet radio. The keyboard on these Sony's works in the matrix, you have to unsolder quite a few components from the front panel, replace all the switches (due to their age) and solder a few resistors. I don't have it drawn up like that right now. I'll take a picture and post how it is on mine.

Start by reading the service isntruction:
https://elektrotanya.com/sony_st-s120_sm.pdf/download.html
Unfortunately here is a matrix keyboard, so you will not be able to use the ADC input.
.

@robgold That would be great, I can handle the unsoldering, I have 6x6 switches so I'll embrace the replacement.

I've updated, didn't help.
I'll do a prock cleanup to start with and reconfigure everything.

@simw Just working in this matrix is the advantage here. Throw in a couple of resistors so that each button generates a different value and it works.
Red wire is 3.3V, black GND, white ADC input. This is on the radio board itself pulled up by 100k to +3.3V

I was more referring to the fact that you need to do more modification than just "attach the ADC to the connector to the tuner board".

And this is some misunderstanding that has crept in. That's right, you have to cut out all the diodes that are on the schematic by the keypad, I soldered everything in general. In addition, under the display you need to make a cutout for the OLED connector.

Do yourself an OTA Update and tell me if it works. Have you refreshed the page ? The browser does not keep it in memory ?

Unfortunately with me the OTA update resets the player. Strange that time there .
Cleaning the memory did not help, removing the card did.
I reformatted, but after inserting it again it is impossible to switch to another station.

v3.17.53 on GitHub. Mainly I corrected two issues - when selecting a bank via the page, the display was showing "bushes" and station selection via the encoder. The radio was not "clearing" one flag causing the OLED to take a long time to refresh.

@simw What settings do you have in Arduino ?

I changed the partition scheme as it is on github and it no longer resets.

After loading from OTA it still doesn't change stations if the SD card is in the reader.

Does everything work for you via the website?

OK, delete the configuration files, last station file, last bank file, generally try with a clean card. You will have to click the configuration through the www. The rest should load. At most, copy the banks to a disk somewhere for a while if you have your own stations.

Have you uploaded the icons? ICO and PNG file on the card? The browser is constantly asking the server for these two files and there will be an error in the browser console, maybe this is blocking your refresh.
