Hello everyone,

I retired recently and now I have plenty of time to enjoy my hobbies.

One of the first projects I started is this KaRadio. Since I have a few ESP8266 floating around I programed one unit with the ESP8266 software (Rel. 1.7). I connected a 1.3inch Oled Display via a Arduino Uno. Everything runs fine except two issues:

1. I wasn't able to change the baudrate on the ESP8266. Whenever I entered the command "sys.uart("28800") I get the response "low memory". I do have have only 6 stations programmed. As a solution a changed the baudrate setting in the file karadioU8glib to "#define  BAUD       115200" (line 55).  So the display is now showing all informations.

2. The date and time are not being updated on the display. After powerup it displays January, 1. 2000 and the time starts to run at 00.00.00. But it never updates the date and time. Is this function not implemented in the software?

One additional question: Should I go on with  this Software or should I go for the ESP32 Hard- and Software?

Best regards

Hans-Juergen

p.s.

Thank you very much for this excellent work and for sharing it

Hello Jean-Pierre and everybody!

Could you advice me? I'm trying to do KaRadio32 with the ESP32 Devkitv1, but something's wrong. I suspect "Flash download tools" can't do with my ESP properly. 

First it couldn't download KaRadio32 to the ESP32 (esp_sync_blocking), but later I managed to erase (only pressing boot while ....._____....._____). Only after this I finally loaded KaRadio32 to my ESP32. I linked it to WiFi but monitoring worked during near minute and finished. Maybe the device is defected? But later I installed Mongoose OS to the ESP32. It worked and exchanged data via WiFi. I've not recieved an amplifier from Aliexpress yet, so can't test lineout.

Is there another loader for ESP32, not "Flash download tools"? And maybe I can do something else?

Thank you in advance!

Hello Jean-Pierre,

somehow I managed to get contact to the ESP via my mobile. When I first entered the wifi-settings, I broke up to fast: I only filled in the information for my home-ssid and its passowrd, then I accidently saved before I filled in the IP-adress of the router. Now I cant find the ESP any more in the WiFi-net. What can I do?

Thanx!

Edit: I maneged to fix the problem. Actualy it was a network problem, so it has had nothing to do with Karadio.

Thanx for the effort creating this great internet-radio, Jean-Pierre!

kindly there is someone who can show me the schematic and code to used an LCD 16x2 and control with three keys. thanks

Hello, I build this project with a esp32 and all run for the best but i would like to move the VSPI pins (18/19/23/5) to the HSPI pin (12/13/14/15) for a simplification of a PCB design and  this don't run.

The web and telnet is OK, i can use the radio but nothing is display on the LCD.

(Type 197 ) 

I test the screen with another soft and it'ok.

I checked all the GPIO.H and all the files where SPI is called but i didn't found where i made a mistake.

Could you help me ? 

How can I?Send the gpio.h may be

Take it at http://karadio.karawin.fr/KaRadio32.bin
Thanks, I forgot to mention it.

Thank you so much ! Sound over vs1053 as well as I2C-OLED are running now. So nice !!

Unfortunately after some minutes it stops music an does not respond until repowering..?

See on telnet or uart log if an error is found..

Mmh, using telnet/uart I was able to change to the correct display, did a system reboot and an ota update...so that all works nicely.  Log does not show any errors. Log states "playing". So I tested it with vs1053 patch (what is it for?) and without...same behavior, it suddenly stops audio after some short time.

For all url?

"For all URL?"

Seems so. Whole yesterday evening I tested and had Trouble even with local Radio streams. Webpage and LCD still running until a station Change, then it completely hangs. I will reorder some Hardware.... Interestingly I used exactly this VS1053 with an ESP8266 and your Software without issues...

Hah, it is working now ! It seems to be an issue with the ESP32. I used a new one and now its perfect !! Also, I think its running faster now...

Best regards,

Mike

Dear JP,

I have an ESP32-WROOM on my desk and want to built your radio.

Unfortunately, I cannot find the "build/karadio32.bin" in your github!? 

Where are the install binaries located ?

Thank you in advance,

Mike

Hello JP,

are there any known stability issues in 1.6.3?

I tried to build a new  Karadio and after updating  to 1.6.3 i have bootloops.

Tried on different modules. After Reflashing back to 1.0.8 it works stable.

Any Idea?

Thanks

Thomas

From 1.0.8 to 1.6.3, it is a big jump. I think that it will be useful to erase all the flash eprom, all 4MB.

I have the binaries 1.0.8 laying around. And ever i build a new karadio i flash them and than i update via the Webinterface Update button.

But you're right. It is a big Jump. I will download new binaries from your Github, erease the whole flash and try again.

Flash Pattern is still identical?

1. Boot

2. User1

3. User2

4. blank

5. blank

6. default

7. default

Thanks

Thomas

The saved data structure is not compatible with the old one.
<try https://github.com/TridentTD/ESP8266FactoryReset to erase all.

I configured addon.h and gpio.h as following:

#define LCD_COLOR 128 //0x80
#define LCD_SPI 194 //0x40
#define LCD_I2C 0
#define LCD_NONE 255

#define PIN_LCD_CS GPIO_NUM_14 //CS
#define PIN_LCD_A0 GPIO_NUM_27 //A0 or D/C
#define PIN_LCD_RST GPIO_NUM_33 //Reset RES RST or not used`

compiled OK, stations receive OK
sys.lcd
##LCD is 194#
but after start I see very very slowly LCD filling with light blue and nothing more.

Your mistake is on addon.h. It must not be changed.
#define LCD_SPI            64 //0x40

The lcd type is set by sys.lcd command.

Thank you for fast reaction.

I corrected it with no result. Additional test results I putted on github page.

Is it possible to add a radio on / off function at the specified time in the project on ESP32?

Thank you for the project.

I do not have enough cyrillic fonts, please add

Hello JeanPierre. Thank you very much for your great useful work for us. I want to modify my radio (add the WEB function to it) So I had an little idea about it, maybe she is not new, of course, but I decided to share it with you. My radio on the side can play files from USB, Micro SD, Bluetooth and AUX. Also my radio have a Ir RC. Aliexpress sells many similar low cost modules.  The idea of controlling my radio by 1 wire (through Ir line) - by small means we get more opportunities. 

How do you like this?

Hello JeanPierre, first of all ,thanks for the beautiful project.

I've built one (KaRadio-32 with integrated addons) and an LCD ILI9341 194 // 240x320

Everything working fine but the image is shifted to right by abt 20 pixels,any possibility of fixing it ?

Thanks

Mauro

Look at the lcd switched off. You will see that it is the lcd itself with a black array on left.

bonjour Jean-Pierre 

Je m'appelle aussi Jean-Pierre : j'ai 66 ans et j'aurai besoin de votre aide pour adapter votre système pour ma mère de 86 ans... elle écoute France Inter en WiFi mais elle devient très maladroite...je vous dis quoi (je suis chti) par Mel : mode Ip. Merci

Hello Jean-Pierre, thank you very much for your wonderfull project. I have some problem with lcd display ( ili9341) initialization . I can see just:

Karadio

(c) Karawin

IR+clcd V1.1

IP:

and nothing more. I use arduino pro mini + lcd ili 9341 + karadioUCglib. Uart speed 28800 same on arduino and esp 12f. (ucglibConf: Ucglib_ILI9341_18x240x320_SWSPI ucg(/*sclk=*/ 7, /*data=*/ 6, /*cd=*/ 5 , /*cs=*/ 3, /*reset=*/ 4); ) All worked on 5110 lcd. but i haven't it now. Can you help please? 

ps: sorry for my english =-)

Probably a problem of uart if nothing seems received. I don't have a prototype to test it.

Hello. At me the offer to the author, to add the timer of inclusion and deenergizing on time.

Hello, for quality sound it is important to know the level of wi-fi signal. Is there a possibility to bring the level indicator wi-fi access the management page of Karadio.

I tried some time ago, but it broke somethings. I agree that it is a good feature. I will try again.

Done in 1.6.2

Many thanks for your promptness. Updated to 1.6.2, the wi-fi indicator is working.

Hi JP, i have a big problem. After upgrading from 1.1.7 to 1.6 I have no sound anymore. The slider for loudness goes from minus 127 to 0. Is there a change from a variable to a signed type? I tried to enable the patch as well but no success. Any further Idea what to try?

Thanks a lot and have a nice Sunday

Thomas

It seems that your vs1053 doesn't like the vs patch. To disable it on the uart interface or with telnet type the command
sys.patch("0")
and reset the esp8266<

The slider in db is from -127db to 0db

Or may be another problem on wire because it is the only cause i can imagine. See the log on the serial at the beginning to see if the vs is well detected.

Hi JP, it seems to be a defect in Flash memory.

I tried several things. A reflash ended in a blinking Pattern twice a second and no serial output. So i assume the flash is dead. I replaced the ESP8266 board and now it runs good again.

Regards

Thomas

Hi,I like your projekt very much.
Now i have a little problem with the OLED Display.
Sometimes it loses connection to ESP and the Text  becomes  static.
I use a Wemos D1 mini and the Arduino ATmega 328 mini pro 8Mhz 3.3V to
drive the OLED. I also use IR and the Switches.
When i set the uart speed again (sys.uart("28800") it works
for some time, only the displayed Ip at startup is then 0.0.0.0 But Sound is ok and the "real" IP is also reachable with the Browser.
I work with Version 1.6 and i believe it worked better with 1.4 in my Case. Any Ideas?

Is it possible to make a soft reset from the ardruino 

from the arduino? I don't have an arduino on this project apart the addon for lcd and controls. Anyway, to send a reboot on the serial, the command is
sys.boot
