    For ESP32 see the github page KaRadio32.

    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.

Can somebody please help me. When running KaRadio32 on a ESP32-Wroom-V4 together with a VS1053/1003, but also when using a UDA1334A via I2S, I get an audio signal on just one channel.

Bonjour Je me permets de vous déranger , je viens de réaliser la dernière version 2.2 R1 un grand merci tout d'abord pour votre super boulot, j'essaie de mettre un ST7735 I2C comme écran et après plusieurs tentatives je n'y suis pas arrivé ( par contre LCD_SPI_ILI9341  et   LCD_I2C_SSD1306 fonctionnent parfaitement)

Auriez-vous des conseils de câblage svp ?  (  CS,DC,RST,SDA et SCL)

merci encore

c'est un ST7735 128x128 mais I2C pas un SPI et je n'ai pas trouvé de code équivalent j'ai pourtant  essayé le câbler en I2C sur  :

// I2C lcd (and rda5807 if lcd is i2c or LCD_NONE) //------------------------------------------------

#define PIN_I2C_SCL GPIO_NUM_14

#define PIN_I2C_SDA GPIO_NUM_13

#define PIN_I2C_RST GPIO_NUM_2 // or not used

peut-être avec un autre code serial mais lequel je n'ai pas vu d'équivalence dans la liste

Hello!

First of all this is a great project. Is it possible, to add a rotary encoder or some buttons for changing the saved favourite radio stations? This would be a great feature, especially for people who don't want use a smartphone.

Thanks in advance

The O-led with arduino mini  addon work now , but the  date display  only  "01-01-2000' and the clock work like a function time counter , it count the time from powering on  .What can i do to fix this ?  Thank you !

Jean-Pierre Cocatrix wrote 01/30/2021 at 21:42 • point

This is because the request time from the mini is not received by the esp. Check the mini tx ---- rx esp wire

  Are you sure? yes | no

josefburgersanktmartin wrote 01/31/2021 at 08:43 • point

in my schematic the wire mini tx ---- rx esp not exist ,   only tx from ESP 8266 to rx mini , i have only 3 wires from radio to mini , 3,3V GND and  tx esp to rx mini

  Are you sure? yes | no

Jean-Pierre Cocatrix wrote 01/31/2021 at 08:50 • point

Yes a mistake.
but in u8glibConf.h you can read:

The tx of the pro mini must be connected to the rx of the esp12 but
Warning; the esp rx pin is not 5V tolerant, so if your pro mini is a 5v version we nned to adapt the level.
-------
See
http://www.instructables.com/id/Pi-Cubed-How-to-connect-a-33V-Raspberry-Pi-to-a-5V/

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

hehaipeng wrote 12/14/2020 at 05:15 • point

hank you! Production completed. It's just that China's radio streaming media does not support the display of radio program information, and the display screen looks ugly and harmonious. I want to adjust the screen display layout and enlarge the font, but I'm not very familiar with programming, and I'm only good at hardware. Hope under the guidance, thank you!

Hello,

I have installed your Software on two ESP32 systems and booth working very well, i have only two suggestions.

1. sometimes after power the radio, the ESP32 don´t connect to the wifi and start instead the AP, the router is not far from the ESP... and next time the ESP connect to the WIFI, maybe it is possible to programm a routine, when AP is active, check every 5 minutes to stored WIFI networks.

2. somitimes when i switch a light in the near of the Radio, i hear a knock at the speaker and the radio is loudless, after a restart the radio is working well. Ithink the problem is the VS1053, maybe it is possible to check if the VS1053 is working, if not, give him a reset.

  Are you sure? yes | no

Martin Fasani wrote 01/15/2020 at 15:23 • point

I have a suggestion about that: Instead of using WiFi manager, let WiFi configuration come from Bluetooth serial or BLE (Serial is a smaller lib)
Here there is an example: https://github.com/martinberlin/Remora
There is an Android app called "ESP32 WiFi setup over BLE or Bluetooth Serial" and then you can easily setup the Radio via Bluetooth

  Are you sure? yes | no

Hi,

I like this project but haven't had much success. I'm using a nodemcu v.3 with an ESP8266 and a VS1053. After flashing the nodemcu, I can see a response from it in a terminal program. Following the directions in the response, I can connect to WifiKaRadio successfully, but when I enter 192.168.4.1 in my browser, it says "This site can't be reached." There is also no result pinging that IP address, but 192.168.4.2 does respond to the ping. I can't get any farther than this.

Can anyone help?
