  • gzipped html tranfert. More stable and improved speed
  • The page content follows the header size.

History:

history

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.

Hi JP, how is the correct Syntax to Change UART Baud over Browser?

Thomas wrote 02/18/2017 at 10:05 point

Hi JP, i already found but dont understand. Is it 192.168.2.136/sys.uart("19200") for example? This Dont Work so i guess my Syntax ist wrong

  Are you sure? yes | no

jp cocatrix wrote 02/18/2017 at 10:11 point

Two different interfaces: 
On browser:

192.168.2.136/?uart   revert the uart to 115200 until a reset. Useful in case you don't remind the current speed.

But on the uart interface (serial on tx rx)
sys.uart("115200")
Or other speed to change the uart baud rate on the next reset and forever until another sys.uart command.

115200 is the default. Before connecting a display controller, you must change to 28800.

  Are you sure? yes | no

Thomas wrote 02/18/2017 at 10:23 point

Ok, its a pitty. I  thought it could be adjusted on browser also. Is it possible to read the curren setting of baud on the browser? I unfortunatly have no communication between display controller and Esp . And want to check this first before Disassemble my Radio to connect it to a computer.

  Are you sure? yes | no

Thomas wrote 02/20/2017 at 11:07 point

Hi JP i know that your Standard setting is 28800. But i changed it both to 19200 because 28800 is not selectable with Arduino Serial Monitor. This works fine for me, also with IR Receiver on a pro Mni with 8 Mhz and 3,3 Volts.

In the past i had sometimes trouble with self changing settings on the Baudrate.

But in this case i checked now with computer, it hasnt changed.  I detached the esp Module and mount it again, and now Display works again.

It seems that my build on a protoboard is not much better than on a breadboard.

Thomas

To replace the vs1053? No, absolutely no, it is the stream decoder (mp3 aac etc).
But you can add a bluetooth transmitter after to send audio.

When the stream disappear, a connection is retried once.

It play well! but only with the patch.
Without it, the vs1053 crash.

If the patch is loaded you see:

VS Version (VS1053 is 4) = 4
SCI_ClockF = 0xB800
I2S Speed: 0
plugin size 18ce 2 c67
plugin start: 7 1 8050 6

Do a sys.patch ( "1") to enable it again, and reboot.

Are you sure to have the last release? Do an OTA upgrade please.
This is an alpha command not yet documented.

Yes. Already there were rows in the log

  Are you sure? yes | no

jp cocatrix wrote 01/26/2017 at 17:49 point

The free ram memory is critical. So i am not sure to implement mDNS.
Less critical is the ip conf for each AP.  For the moment I recommend to use a static DHCP lease to avoid the need of two fixed IP. With a well configured router, it is transparent. That's why I added the MAC address. I have to develop a new bank in eeprom to store more permanent configurations. The first one is full, that's why I postponed the second IP.

Thanks for your suggestions and appreciations.

Технический паспорт для vc1053 рекомендует конденсаторы 22 мкФ в силовых цепях.
Установленная на плате модуля С17 и С18 были сомнительными номинальным.
Под руки были только 100 мкФ.

The value of the resistors is not critical. Only the ration 1/3 2/3 must be respected 1k and 2k for example)

Hi JP, 

Autoplay dosn't work correctly, every time I turn the player on, I have to press the play button, to start the radio playing

  Are you sure? yes | no

jp cocatrix wrote 01/24/2017 at 02:22 point

update please.

  Are you sure? yes | no

Sergio wrote 01/24/2017 at 11:00 point

With the last update, i don't have sound with any stations

  Are you sure? yes | no

jp cocatrix wrote 01/24/2017 at 12:22 point

Do another ota update, and enter the command on uart:
sys.patch("0")
And reboot again.

I wonder why your prototype doesn't like the vs1053 patch.
Are you alone in the world? May be some other problem on wire can explain it?

  Are you sure? yes | no

Till i'm update the player  to the last update works ok, the only problem was that the autoplay doesn´t work ok. No wire problems, i´ll try with the uart command that you said. 

  Are you sure? yes | no

Sergio wrote 01/25/2017 at 00:10 point

now works, on 2 players i have to entered the command on the uart

Thanks, may be a problem with the VS1053 patch

  Are you sure? yes | no

The vs1053 patch is the official one. No problem with it. May be a spi error on transfert? The wires are longs between the esp and vs?

  Are you sure? yes | no

May be. The power supply used DC-DC step-down module LM2596 powered by the voltage regulator +12 V boom-box.
ESP8266-12 randomly stopped communication with VS1053, assuming a fault ESP8266-12 replaced it ESP8266-7 effect it is not received, the modules behave as well. Only extra capacitors ensure their reliable operation.

  Are you sure? yes | no

May be a high frequency filter with a few pf, and a 22µf on the 5 volts only?

  Are you sure? yes | no

vis22 wrote 01/22/2017 at 19:04 point

The recommended VS1053 module has to install additional capacitors 22 microfarads in parallel of C17 and C18 to the supply chains. Without them, the module sometimes freezes.

  Are you sure? yes | no

jp cocatrix wrote 01/22/2017 at 19:25 point

Never seen on more than 10 prototypes. 

May be a power supply problem on your prototype before these regulators?

  Are you sure? yes | no

Hi, what caps do you recommend, just ceramic SMC's?

  Are you sure? yes | no

jp cocatrix wrote 03/14/2017 at 18:07 point

I never experimented a freeeze of the vs1053.

HI T4SPAM,

exactly


amp would be activated only during playback
(It prevents clatter at start-up)
the rest suppresses  filter

Great. Pin D4(GPIO2) is already in use for LED on Button Interface.

But we can use Pin Playing 12 on LCD MCU as well.

Regards

Thomas

Pin D4 (GPIO2) is already in use for LED on Button Interface ...

I would therefore suggest a new feature firmware for ESP8266
configuration GPIO2

LED out

or
amp control

thus enabling control amplifier without display

Please excuse my bad English

Yes, I can also add a sys command to choose between the blinking default and the playing status on gpio2

  Are you sure? yes | no

HI jp cocatrix,

It would be great
Thank you in advance
Archetix

  Are you sure? yes | no

jp cocatrix wrote 01/20/2017 at 16:38 point

No problem. in the next release

sys.led("x")  with x=0 default blink, x=1 led On when playing (state saved in eprom)

Ok?

  Are you sure? yes | no

archetix wrote 01/20/2017 at 17:58 point

OK
Thank you very much
