Thank you for the wonderful development of the project. Thank you for the opportunity to add to the user agent of change. This will give the opportunity to listen to interesting radio streams.
display Connection - it is also very good news. The touch screen would be useful in this project, because it can be used to control the device.
Nextion fairly expensive option, but very beautiful. In the future will connect the circuit and code?

I will develop a range of displays including a touch creen but may be with another more powerfull cpu than the pro mini. See the LOGS https://hackaday.io/project/11570-wifi-webradio-with-esp8266-and-vs1053#menu-logs

And as usually, i will deliver software and schema for free. It is my hobby.

Thanks

In progress: yo2ldk has made a prototype.

Hi,

the PCB is for this design here:

http://piotrsperka.info/2016/06/odtwarzacz-radia-internetowego-esp8266-cz-2/

Anyway, i try to do it on my own. That could last a while because im a totaly Beginner :-)

Hi Jp cocatrix,

are there any PCB recources for a minmal Webradio.

The ones in the Kicad Folder seems to be not up to date.

Thanks Thomas

What is missing? The pcb is a work of piotrsperka, not mine. I dont have the knowing to do that. Tell him directly.

Thanks

ok, I try to start play a link, via serial:

 cli.url("http://5.39.71.159";)

##CLI.URLSET#: http://5.39.71.159
#INFO:""#
cli.path("/listen.pls")
##CLI.PATHSET#: /listen.pls
#INFO:""#
cli.port("8994")
##CLI.PORTSET#: 8994
#INFO:""#

  now, if I give cli.start, ESP module is blocked, need to reset it.
How can I send via serial to play that link for example, with one send command?
 (try it with "&" between command - not recognized)

Please remove the http:// and it will work.

Hello,
I've problems with autoplay. I use v1.1.0. After power
off the esp8266 reboot and connect to wifi and you can see that station 0
select but i didn't receive information or the stream. I need to change
the station first, then the stream work. After that i change to station
0 all is working but without changing the channel, autoplay don't work.

Just uncheck and check again the Autoplay. It will trigger the state of the autostart on the esp8266 eeprom.

Yes i know, it is a pity, but you have to do it once for your life ;-)

Hi, thanks for the nice effort you already did. The instructions are perfect to follow. In de sound I have some lite ticking. I put already some elco of 220uF and 100nF on the powerline and changed the powersupply, no better result. Do you have any idee how to solve the problem?

I am playing for the moment with a Nextion touch-screen ( exist in different sizes ) and esp8266, is that not a good display to use in your project? All the screens are saved in the display driver so, no use of alot of memory in the esp8266.

No idea. Is it a regular tick or random tick? Try to look at you ground wires. Try to shield your prototype.

The memory is not the main problem for the screen. The problem is the lack of gpio on the esp8266 and i don't want to add external components to multiplex them.

I am developing an external screen based on the uart interface: A little processor like the arduino mini pro (or compatible) and a basic screen. The advantage of this approach is that with a canvas for one screen, every models of screen can be adapted. This mean that at the end you can have a big library for everyone and everybody will be able to modify the appearance to cop with his taste.

I will have a look to the ground loop. It is not a regular tick. If I start the radio then the tick is faster then when the radio is off. I use the 3v3 regulator of the mp3 board to supply the esp8266. Could that be a problem? The nextion screen works with uart and needs only 2 wires. It has his own processor on board. So you dont need a extra arduino to use it. It comes also with a editor to create the screens and test them. It had mine for less then 15 dollar ( 2.8" ) mail included from ebay.

The vs1053 must be wired to the 5v VU of the nodeMcu.
Another user try to test with the nextion. I will comment it if he succed.

Yes, the user-agent is an interesting subject.
For Karadio, i send a user-agent  Karadio\1.1.0.

If you send a user-agent as mozilla or chrome etc, you don't have the stream but only an html of status. But if you add a ; to the address, you receive the stream. It's a trick.

With a user-agent "karadio", I don't have the problem with all stations I know.

I tested your station with karadio\1.1.0 without success, but after, i tested with pcradio, and it works but for one second, and the decoding of the stream hang. I will analyze more to see why.

Thanks.

https://drive.google.com/open?id=0B-4TW9qHjNsjME9sZlBkaTBqb2M

I used this XML file. This is the app for Android "PCRADIO". This working radio streams. Only need to change the Usera-agent. The ability to change The user agent makes the device more flexible.

Hey, 1.1.1 will add your specific needs

Hi Jp cocatrix,

its me again. Thank you for your fast implementation of the sleep timer :-)

Actually i finalized my first control panel, and there seems to be a bug regarding the volume logic. I can only switch between to states, -17 db and -14 db. Other buttons works as expected. Do you have a idea?

I dont use the buttons start and stop because i have not enough and they are not soo important. The resistors are in place.

Thanks a lot

Thomas

No idea. It is just a voltage seen from adc. If it works for -17 and -14 it must work for all.

Check and check again. Test the voltage on adc and 3.3 and gnd...

if (system_adc_read() < 10) adcdiv = 0; // no panel adc grounded
    else
    // read adc to see if it is a nodemcu with adc dividor
        if (system_adc_read() < 400) adcdiv = 3;
            else adcdiv = 1;

void switchCommand() {
    int adc;
    uint8_t vol;
    char Vol[22];
    if (adcdiv == 0) return; // no panel

        adc = system_adc_read();
        adc *= adcdiv;

        if (inside&&(adc > 930)) inside = false;
        
        if ((adc >400) && (adc < 580)) // volume +
        {
            vol = VS1053_GetVolume();
            if (vol <244)
            {    
                vol+=10;    
//                printf("vol %d   vol1 %d\n",vol,vol1);                    
                sprintf(Vol,"%d",vol);
                setVolumew(Vol);
            }
        }
        else if ((adc >730) && (adc < 830)) // volume -
        {
            vol = VS1053_GetVolume();
            if (vol >10)
            {    
                vol-=10;
//                printf("vol %d   vol1 %d\n",vol,vol1);                    
                sprintf(Vol,"%d",vol);
                setVolumew(Vol);
            }
        }        
        if (!inside)
        {    
            if (adc < 200) // stop
            {
                inside = true;
                clientDisconnect();
            }
            else if ((adc >278) && (adc < 380)) //start
            {
                inside = true;
                sprintf(Vol,"%d",currentStation);
                playStation    (Vol);
            }
            else if ((adc >830) && (adc < 920)) // station+
            {
                inside = true;
                wsStationNext();
            }
            else if ((adc >590) && (adc < 710)) // station-
            {
                inside = true;
                wsStationPrev();
            }
        }
}

Seems to be a cold junction or somewhat else.

I changes nothing bu now it works.

Have a nice week.

Thomas

Cons not in your project, but in someone else's. In your project easier firmware process for the novice. While it's difficult to judge, first you need to do. I think the project is better to use a more common displays that can be purchased on aliexpress, ebay.

https://github.com/Edzelf/Esp-radio

This is another internet radio project. This project has its pros and cons. I like more your project. 

Tell me the cons ;-) (apart the hardware display that is coming)
I will change it to pros if possible.

Yes, i know this project and other obviously.

Thanks.

Thanks.

I am studying a complete list of display for karadio. From a small one to a large touch display. But it take some time... 

All based on a mini pro arduino.

Thank you for a wonderful project. Let's wait for the development and continuation.

I build a Webradio based in your Instructions. I works wonderful. Thank you so mich for sharing your project. One question, for what is the optional RAM ? It works perfect without it?

One suggestion for a furher release. It would be  great if a sleep timer would be possible.

Regards

Thomas

Great,

Stay tuned, the next release will be far better with drag and drop of the list of stations and a theme changer (clear or dark) (and a great speed improvement for all functions).

The external ram is for weak internet connection to improve the receive buffer.

Your suggestion is great. But i can only stop the play state, not the power ;-)

I will code it on the next release.

Thanks.

 Hi,
How can I know if esp is connected on internet ?
 I cannot heard anything on output, or is vs module damaged ?!  :(

When connected, it blinks blue for 10% and off for 90%.

Connect a terminal windows via usb at 115200auds to have some traces.

I like this one http://www.compuphase.com/software_termite.htm

Check your connections between esp and vs

Bye

 All is OK now, Thank you !

I have one MP3 decoder board burn ..

 All connections was made it well but,  I put an Phone headset (who have 4 rings), and maybe was some short circuits on output so, don't do it like me !!!    :)
  BTW, mp3 board have in-scripted VS-1053 but chip is 1003, and perhaps that's way auto play not start 

Check the vs model within the trace:

VS Version (VS1053 is 4) = 4

The autoplay depends on the  autoplay setting. Change it to activate the autostart.

 On 320 kbs stations, audio is very crispy . wifi and internet connections are high speed; need to put external RAM to hear it continuous ? 

Yes some stations give me some trouble. What is your station?

It seems that the esp has some difficulty to read the stream. May be a html problem? I need to analyse a bit more.

this one for example

http://www.internet-radio.com/servers/tools/playlistgenerator/?u=http://38.109.219.207:8020/listen.pls&t=.pls
 

BTW  I made upgrade by wireless to the new version ( great feature ), who look very nice !

Unable to understand why this station is not good. I am unable to receive at the good speed.

I tried with these ones: http://www.hionline.eu/streaming-url/ and they are ok.

Strange.

Hello, i need to change the baud rate from 115200 to 9600. What can i do ?

Good question. 
A compilation is needed.

BUT

I will add a command on uart interface in the next release soon:
cli.uart("x")

With x the uart baudrate at the next reset and permanently.

The command will reply with
##CLI.UART= 115200# for example to check the speed.

Notice that if the x is incorrectly entered, the interface may be unusable.
cli.uart  only will display the current baudrate.

ok then i wait for new release.

The 1.0.10 is available on ota update.

"Release 1.0.9

- New I2S external DAC interface on the vs1053. The I2S is enabled by default to 48kHz. To change the speed permanently use the uart interface with the command :cli.i2s("x") with x =0 for 48kHz, x=1 for 96kHz and x=2 for 192kHzThe i2s interface is available on the alientek vs1053 with i2s_sclk on SCLK (GPIO16), i2s_sdata on SDIN (GPIO07), i2s_mclk on MCLK (GPIO05), i2s_lrout on LRCK (GPIO04)."

Hello.
I downloaded a program version 1.09.
But I still do not see the I2S signals at the terminals GPIO06(pin 11), GPIO7(pin 12), GPIO5(pin 25), GPIO4(pin 36) VS1053

Great project, i build one today, and works great

I built the minimal solution with Nodemcu 0.9 and LCSoft VS1053 module for less than 10 Euros, great! Now I would ike to 

1) understand the coding (so many includes and other files) Which firmware is used as a basis? I see that this is C Code, so it's not the lua firmware but it also seems not to be the arduino firmware. So what is this project using? I think, I found it out myself, it is RTOS, isn't it?

2) Connect a Nokia 5110 Display via SPI interface. How do I do it? I found a similar example on https://github.com/Edzelf/Esp-radio, but this is using the Arduino for ESP8266 platform, so the code will most probably be incompatible. Can anyone help me? The connection is clear, but the code isn't. Where do I finde a library for this display on RTOS?

3) know, if connecting the LCSoft VS1053 to a Stereo Amplifier (Big Onkyo from my Stereo System) can damage the amplifier or the module? I read on a German forum that Capacitors in the earphone lines probably have to be added to filter out DC. Do I need these? Which size is recommended?

4) know, if is possible to set the LCSoft module into MP3 mode by software. As described on http://www.bajdi.com/lcsoft-vs1053-mp3-module/ I had to solder a bridge between pins33 and 34 which was terrible with my large iron, to get MP3 mode on startup. I read somewhere (but I dont' find it anymore, that the module can be set to MP3 instead of MIDI mode by sending some codes after startup. Has anybody done this and knows how to do it in this project?

5) know what happens, when I am in a different WIFI-Network, where my SSID is not found. Will the radio start itsown access point again like at first start, or do I have to change the SSID and password for a new network as long as I am in the current one? Or do  I have to change this via serial interface?

Anyhow, great project! I think about making a tutorial for beginners on instructables.com where I explain how to build this project from scratch. I'm just waiting for some parts to build a second ona and take pictures from each phase. 

Hi,

1/ just a notepad+ editor or vi under linux. It is a freertos project.
Based on https://github.com/espressif/ESP8266_RTOS_SDK

2/ No free gpio available for that.

3/ With the alientek module, the capacitors are included, but not with the cheap one.
It is very simple to add them on a board but most of the amplifier include them at input. Never had problem on amplifier or amplified speakers.

4/ The needed code is already added to the soft. No needs to soldier pins.

5/ If the ssid is not found, the ap mode is started. No problem.

I plan to write an instructable, but now i am stuck in a chunked transmition bug.
No time for the moment.

If you want to do it, great. Some snaps:https://www.dropbox.com/sh/0rbq6r2iz41ujhm/AAD5I_wriYIe-xeLZGWPJSpQa?dl=0

Thanks

See http://www.instructables.com/id/Wifi-Webradio-With-ESP8266-and-VS1053

Got it running fine on a Wemos mini board (ESP12 with pins broken out) http://www.wemos.cc/Products/d1_mini.html but not sure how to wire up the additional RAM .

Fantastic project and works well but was getting a bit of a buffer issue so I tried to wire in the extra RAM.

Can you confirm how this wiring is supposed to go as I am not sure on some of it:

Numbers are obviously pins on the RAM

1:CS/=GPIO16   <- does this mean it should go to either the CS on the MP3 codec board or GPIO16 on the ESP board or both? 

2:MISO=GPIO12 same here, is it both?

3:NC   -> don't connect this one

4:GND  -> Ground obviously

5:MOSI=GPIO13 <- again is this joining all three pins?

6:SCK=GPIO14 <- as above

7:GND  <- Ground obviously

8:3.3v <-  3.3v :) 

Thank you for all your work on this,  it is awesome :)

Hi, GPIO are those of the esp module. 
Spi is a bus with shared miso, mosi sck. Only cs need to be particular to each device.

If your chip has a /Vhold in place of /VBAT (lcv chip), the pin 7 must be wired to VCC otherwise to gnd.

Thanks

Hi, what a perfect project.  I downloaded the files from Github, but for the blank.bin there I have No Download Button. Where can I find or make myself that blank.bin file. Thanks for everything

in ESP8266-Firmware/bin/  on

Thanks

Thanks, I used now a different pc and the download works.
