    ESP8266 Simplest prototype:

    - Optional external ram (23LCV1024) support (1:CS/=GPIO16 2:MISO=GPIO12 3:NC 4:GND 5:MOSI=GPIO13 6:SCK=GPIO14 7:GND 8:3.3v)

    Attention:
    The optional led is now on GPIO2. The blue led on the ESP8266 is blinking at the same rate.
    GPIO16 is now the Chip select for the external ram if any.
    The external ram is detected at boot time if present.

    To upgrade to this release, please flash user1.4096.new.4.bin at 0x1000 ,
    user2.4096.new.4.bin at 0X81000 and blank.bin at 0x7e000 & 0x3fe000
    After that, all next updates are done with the On The Air (OTA) feature.
    New binaries are hosted at http://karadio.karawin.fr .

    Loading the esp8266

    First use

    • If the access point of your router is not known, the webradio initializes itself as an AP. Connect your wifi to the ssid "WifiWebRadio",
    • Browse to 192.164.4.1 to display the page, got to "setting" "Wifi" and configure your ssid ap, the password if any, the wanted IP or use dhcp if you know how to retrieve the dhcp given ip (terminal or scan of the network).
    • In the gateway field, enter the ip address of your router.
    • Validate. The equipment restart to the new configuration. Connect your wifi to your AP and browse to the ip given in configuration.
    • Congratulation, you can edit your own station list. Don't forget to save your stations list in case of problem or for new equipments.
    • if the AP is already know by the esp8266, the default ip at the first start is 192.168.1.254
    • a sample of stations list is on https://github.com/karawin/Ka-Radio/blob/master/ESP8266-Firmware/WebStations.txt . Can be uploaded via the web page.

    Please tell me if you succeeded or something more can be done, thanks.

Hello! I install the Sram 23lc1024 and pin 7 to 3.3V, otherwise it was not recognize the memory.
And I make a query. I wonder if you can change the predominant color white of the website by the black background color?
Greetings and thanks for everything!

yes for this chip, it is a /vhold to be wired to Vcc.
The 23lcv1024 is a vbat that must be grouded.
I can add a theme changer in the future.

Hello Just a great project.

The project in its current form is already self-sufficient.
But perfection is not the limit!
I would like to ask: Are there any plans to connect some of the popular display?
Also, I have a suggestion: Add in the initialization procedure VS1053 including I2S output. This allows you to use higher quality external DAC. I think many of this feature is needed.
Thanks again for your work.

  Are you sure? yes | no

I'd also like a display for mine. I have ordered some cheap Nokia 5110 Displays with SPI interface and it should be possible to connect them like in this project: https://github.com/Edzelf/Esp-radio But I have no idea how to modify the code here.

  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 09/08/2016 at 19:55 • point

Only GPIO16 is free if the external ram is not used. 
The code must be modified, yes, and completed a lot to display usefull informations. Not planned for the moment.

May be a future project with the esp32?

I will add a display with a arduino pro mini on the uart interface of the webradio. So with the command panel, It will be complete..

Some 320 kB/s works, other not, and i don't know why. I need to analyse the wifi stream but i don't have the tools for that. I think it is an esp8266 software problem because mediaserv30.live-streams.nl:8086  and other works perfectly at that speed.

Hi, thank you very much for this project. I just built it up and it works a treat! I plan to use it for music distribution in every room with a central RasPi based Radio-Server which is connected to a music source. In order to get it a bit more compact, I also planned to design a PCB but it seems like you already did this as well. Did you already tested the design? Again, thank you for this great contribution.

  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 08/20/2016 at 21:37 • point

Thank you for this feedback. I have not designed the pcb. It is a work of  PiotrSperka at https://github.com/PiotrSperka/ESP8266-WebRadio. I took the project to greatly improve the software, but I have not tested the pcb. I dont have the tools to do that.
As the design is simple, I think and hope there is no problem.

I have problems to flash my ESP with the binaries. I can flash other fw like micropython without a problem. I use esptool.py. Is it correct to flash the following one after another:

boot  0x0000

esp_init 0x7c000

user1  0x1000

user2 0x81000

blank 0x7e000

blank 0x3fe000

I even tried to make one bin like this:

esptool1.py make_image -f boot_v1.5.bin -a 0x0000 -f esp_init_data_default.bin -a 0x7c000 -f user1.4096.new.4.bin -a 0x1000 -f user2.4096.new.4.bin -a 0x81000 -f blank.bin -a 0x7e000 -f blank.bin -a 0x3fe000 radio.bin

No, it's not blinking. And I waited for 5 min now. But you give me other addresses than in the description. So it is

0x03fe000 blank.bin

0x0fe000 blank.bin

0x7e000 blank.bin

0x3fc000 esp init.bin

0xfc000 esp init.bin

And then

0x01000 user1.bin

0x81000 user2.bin

? But you still need the boot.bin at 0x0000 or not?

Sorry for the stupid question, flashing multiple files is new to me. I know the Esp is OK,  I just flashed microphone and that worked.

Is there a reason why u used a different baud rate for user2.bin?

Thanks for your help. I am looking forward to get this going. Great development by the way !

  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 08/05/2016 at 21:35 • point

The boot blank and default  must be done only one time.

No constraint on the speed, the esp is in autobaud when flashing.

If the flash of the user 1 and 2 is succesfull, after a reset, the led is blinking.

YOu must have an esp12 with 4MB

Thanks for getting back to me about playing standalone MP3s.  I wanted to see if the source to your project is available.  
Amazing job!

With some web searching I found your github project.  Note that the description of the project has a broken link to your github project.  

https://github.com/karawin/Ka-Radio

I am looking forward to putting together the project when my VS1053 module arrives.


I am trying to put together a little project using the ESP8266 + VS1053 board that can play Mp3s on the project sourced from a website when I invoke the device. 

Can you point me to where in your code I should go to see how to play an MP3 from a web server?   I tried browsing through your code listing, but I could not see which code is used by your instant play functionality.


  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 07/20/2016 at 10:54 • point

No specific code. Just point to a mp3 file and read it like any other stream.
Missing: a playlist sequential reading. Presently, only the first mp3 is read.

Hi.  This looks like an awesome project.  
One thing I would like to find out is what I would need to modify in order to play individual Mp3 files residing on a web server (e.g., www.somedomain.com/mymp3file.mp3 ) instead of just listening to a webradio station.
