Where can I download TinyXML.h?

....
sorry, was already reported ...

With the SD files playing function added, I add more audio format to play with.
ogg, AAC, wma even flac. every single one works except flac
I had flac plugin upload to VS1053, and it did play but dragging.
is it the SPI ,SD accessing speed or buffering issue?
we are now using 32bit dual core MCU ruining at 240MHz.
should be more then enough to play lossless audio.
where do I start to try improve it?

Hi, when I compile using Arduino IDE, there is an error: "fatal error: nvs.h: No such file or directory"
How to pass compile?Thanks.

Hi Ed,

Still impressed by the ESP32 radio.
I have progres to get the 28-07 version working. Indeed placing he correct preferences. SD is working now.
As I liked the ideer to have the IR, Encoder and free programmable buttons all available for control the radio.
So I had the gpio 13,14,26,27 and 25 working for volume station control working as a charm.
On the new radio I installed also the rotary switch.
My question is is it posible to have these working all or is control only possible or buttons or ir, or rotary switch?
The ir-remote control is on order in China this will take some time.

Like to hear.
Kind regards,
Theo

ps. Is it correct you removed the TinyXML lib.? If so remove also from page two of the pdf.

Hi @Edzelf

More than a problem in your project, it is a general doubt for the ESP32 modules
I have a question about the voltage supported in my esp32.
When I connect the module to my pc laptop, it receives 5V input sent by the usb port, but recommends using maximum 3.9V.
Should I use some type of connection that reduces the voltage of my laptop to connect my esp32 module to my pc laptop?
I use my mobile phone connector which has a 5V output, to power my esp32. Can i damage my esp32 module?
The heat generated by the ESP32 module to be connected to my laptop is high and therefore I am worried to generate any damage to this

Another question, Is there any option to increase the number of stations that ESP32-Radio can support?

thanks

My rotary encoder didn't work perfectly, becuse when I turned it in one direction, than the volume went low and high. I tried to modify the debouncing time delays, in vain.

I separeted the encoder switch and encoder turning interrupt routines. The switch is the original, the turning uses the background that the encoder is Manchester-coded, so it doesn't need debouncing.

The routines with some comments:

void IRAM_ATTR isr_enc_switch()
{
  static uint32_t oldtime = 0 ;                        // Time in millis previous interrupt
  static bool     sw_state ;                               // True is pushed (LOW)
  static bool     clk_state ;                               // True is activated (LOW)
  bool            newstate ;                                // Current state of input signal
  uint32_t        newtime ;                               // Current timestamp

  // Read current state of SW pin
  newstate = ( digitalRead ( ini_block.enc_sw_pin ) == LOW ) ;
  newtime = millis() ;
  if ( newtime == oldtime )                                // Debounce
  {
    return ;
  }
  if ( newstate != sw_state )                              // State changed?
  {
    sw_state = newstate ;                                  // Yes, set current (new) state
    if ( !sw_state )                                       // SW released?
    {
      if ( ( newtime - oldtime ) > 1000 )                  // More than 1 second?
      {
        longclick = true ;                                 // Yes, register longclick
      }
      else
      {
        clickcount++ ;                                     // Yes, click detected
      }
      enc_inactivity = 0 ;                                 // Not inactive anymore 
    }
  }
  oldtime = newtime ;                                      // For next compare
 
}
void IRAM_ATTR isr_enc_turn()
{
// The encoder is a Manchester coded device, the outcomes (-1,0,1) of all the previous state and actual state are stored in the enc_states[].
// full_status is a 4 bit variable, the upper 2 bits are the previous encoder values, the lower ones are the actual ones
// 4 bits covers all the possible previous and actual states of the 2 PINs, so this variable is the index enc_states[].
// No debouncing is neded, because only the valid states produce values different from 0.


  static uint8_t full_status = 0x0001;                         //lookup table index 
  uint8_t act_status;                                          // the actual value of the two encoder PINs
  static const int8_t enc_states [] = 
		{0,-1,1,0,1,0,0,-1,-1,0,0,1,0,1,-1,0};         //encoder lookup table
  
  static int8_t num;
 
  full_status <<= 2;                                          // remember previous state ( shift to the 2 upper bits )
  act_status = 2 * digitalRead ( ini_block.enc_clk_pin ) + digitalRead ( ini_block.enc_dt_pin );  // Read current state of CLK, DT pin
  full_status |= act_status ;	                              // add the actual 2 read bits to the 2 lower bits
  num += enc_states[( full_status & 0x0F )];
  if ( ( num == 1 )|| ( num == 3 ))                           // four steps forward
    { 
      num = 0; 
      rotationcount++ ;                                       // Right rotation
   }
  else if (( num == -1 ) ||( num == -3 ) )                    // four steps backwards
    {  
      num = 0; 
      rotationcount-- ;                                      // Left rotation
    }
  enc_inactivity = 0 ;    
}

is it right?

So the TFT library uses 16-bit colours (which I personally have never even run into before, other than the few times I've said UGHHH when using safe mode on an old Win95 or 98 machine). I certainly didn't know how to work with the raw hex values, and so I went about finding tables of colours and their associated 16-bit hex values.

Then I found something better, and so much simpler.

Thought maybe you might want to add it for the benefit of people wanting to define their own colors for the tft display. In fact, anyone reading can add this super easily to their sketch and start to customize their radio displays to taste.
This simple function allows you to use the much more familiar 24-bit colour defines that are common in HTML and pretty much anywhere I've ever seen colours defined on computers. (and because it doesn't require hexadecimal number format, its even easier: just 0-255 for each color. more is more, less is less.)

uint16_t getColor(uint8_t red, uint8_t green, uint8_t blue)
{
red >>= 3;
green >>= 2;
blue >>= 3;
return (red << 11) | (green << 5) | blue;
}
DONE.

Hello! I very much like the project of radio on esp32. I have such question. Why only ili9163? With other lcd, for example St7735 will be options? Thanks.

Hello,

I am facing distortion on some radio stations. I am not sure if this is because of cabeling (other stations work fine), the station itself or the bitrate. An example stream which causes trouble is: swr-swr3-live.cast.addradio.de/swr/swr3/live/mp3/128/stream.mp3

Here a excerpt of the log:

Getting these reboots seems to be after an MQTT publish while using ihr streams.

@Edzelf Many thanks for the new ESP32 version. I had no problems getting it work on the Feather ESP32 board. The only other change is to undefine USETFT since I do not have the display. It works great using the Web interface. The Web interface is very fast even when playing 256K streams.

The patch follows. I can submit a PR if desired.

What have I done wrong?
there is no need for wiring, just plug in, everything done by software.

Please, give some tips how to compile this project. Your tips for 8266 ware great. Started to install libraries, but there's a lot mistakes like this:

C:\Users\Eugene\Desktop\ESP32_Radio\Esp32_radio.ino:90:26: fatal error: Adafruit_GFX.h: No such file or directory

I used this way
https://github.com/espressif/arduino-esp32/blob/master/doc/windows.md

Just a question: if my MQTT server because of network problems is unreachable then the program tries to connect all the time and playing doesn't work.

I tried to ping the server but I couldn't find a ping library.

Any idea?

Hi,
great work but I am wondering if there is a chance to power the ESP and the amp with the same battery.
I am not very experienced in hardware-layout.
what measures can be taken to reduce noise in the amp power supply?
Thanks and regards
Andreas

Hi Ed,

Finnaly the TFT received and connected.
Meanwhile the 8266 replaced by the ESP32 changed the software for the latest version.
Indeed the 32 looks like more stable. The 8266 I actualy didn,t get it working after all in combunation with the geeetech shield.( lots of so called "glitching" ) there is a signal and data but not understandeble.
In the same time I placed the capacitors across the 5 Vcc -gnd and betweeh XRST-gnd hopefully will this prevent problems with the power supply spikes.
During my playing/testing I noticed that after a reset from the config page I had to give vol+ a push to get sound again. Is this a known bug?
Also after I received my TFT I didn,t get it working. Connect as discribed and tested again. I changed the TFT_ILI963C.cpp file on line 1096/7
No result. Than the blue 1.8 SPI 128x160 board type I realy do not understand this Most problaby this is the key to get my display working. Do you have a clue?
Further more I realy enjoy this project and like to learn a lot not only from the esp32 also from networking etc. A realy nice step further than just arduino.
Greeting
Theo

Get the error message SD Card Mount Failed!
And the mp3 will not play. What am I doing wrong?

Sorry for my question, but, where can i find pinout of this board? Have the same board, but, my google have no results for it
gpio***-d*** and any others

If I turn the encoder in PRESET mode back and forth 15-20 times, than the progrem crashes.
( I must say that the encoder interrupt handler is changed, it is much quicker. I will publish it here. Can it happen that ithe isr routine tries to write something at "the same time"?)

It seems to me, that it happens in the mentioned routine. It happens more often in the 1st call, this example is in the 2nd one.

The last existing preset station is 7 . Shouldn't we check it for max before calling readhostfrompref ( enc_preset )?

The program excerpt in chk_enc() routine is :

   dbgprint ( "chk_enc 1 preset:%d, ",enc_preset);
   delay(100);                                                             // crashes in readhostfrompref ( enc_preset ) !!
   tmp = readhostfrompref ( enc_preset ) ;                 // Get host spec and possible comment
   dbgprint ( "chk_enc 11");
   if ( tmp == "" )                                                     // End of presets?
    {
      dbgprint ( "chk_enc 12");
      delay(100);                                                       // crashes in readhostfrompref ( enc_preset ) !!
      enc_preset = 0 ;                                               // Yes, wrap
      tmp = readhostfrompref ( enc_preset ) ;           // Get host spec and possible comment
      dbgprint ( "chk_enc 13");
  }

and the debug messages (it calls the routine with non-existing sation 9):

Hey Ed, I just followed a link someone else posted and found this product. It seems that the current state of your hardware and even software are likely pretty much already set up to support this feature, and I think it would be really awesome to have available if a stream becomes temporarily offline/unusable due to lag. There has been a few times when I couldn't get a decent enough stream to provide smooth playback (due to my shitty internet, when there's too many people on it). I think that having the option to record data while the unit is turned off to fill in some of those service gaps would be a nice touch.

I'm fairly certain it would be fairly straightforward to implement, (likely just a few lines of code really...) I think you'd just have to find a way to store the incoming data into files that could be picked up and read later on. Would likely be as simple as generating a mpeg compatible file headers/padding/etc. I personally haven't looked into the specifics of the mpeg layer 3 specification before, so I'm not sure what would be necessary exactly, but it seems that all of the necessary hardware is already in place.

Can one connect KY040 and IR remote control?

I have been trying to get the IHR stations working and have continued to fail both on this project as well as the esp8266 version. I feel like I must be doing something wrong?

The specific station I require access to has a call sign: CHBD
IHeartRadio: http://www.iheartradio.ca/big-dog-92-7/
My preset is something like : preset_00 = ihr/CHBDFM # 00 - BigDog 92.7

I'm wondering:
do I have the formatting correct?
Do I need to log in or something like that?
Is that a valid call sign?
Any other pointers?

It seems lately that all of the examples will load and play, with the exception of anything that has to do with IHR. I can't get anything from ihr to play (although it does seem to pull the metadata properly, at least)

I'm going to attempt to figure iout how to cross reference this post and the ihr post from the other platform, since it looks like this one doesn't have nearly as much traffic as the other. #Edzelf/Esp-radio#82

(PS. please don't judge me based on this shitty channel, it's not for me, it's for the guys at work to help ease them into the idea of listening to something else for a change - this is a local station for me).

Is it possible to do on lcd like
https://ru.aliexpress.com/item/84X48-84-48-Nokia-5110-LCD-Module-with-blue-backlight-adapter-PCB/32578048862.html?spm=2114.13010608.0.0.627DNP

Why take out SD random playing function?
I enjoy it very mach, except it is slow when seeking for next song.
But I would like fixing it instead of taking it out!

Thank you for the big job, Ed.

How can I easily correct the wifi access data without loading new init file and without wifi connection.
Background is: I want to prepare a web radio for a friend of mine. How can he connect the radio to his wifi environmet without reprogramming by Arduino SDK?

I meant pinout of this DEVboard))) which gpio of esp32 goes to some pin of this devboard

Google Now spotted this for me, do you know him @Edzelf ?

Hi all,

The latest version downloaded and flashes into my esp32 devkit (DOIT). So far so good.
Also installed the pushbuttons for the volume and preset.
Some where some how I run into problems which gives the follow malfunctions, it is not possible to run thru my station list up/down. not even preset is possible also the sd card is not readable no files on sd ( there are ).
Looking on the internet I found some issues related to the flash error "flash read err, 1000" looks like this is most probably the problem. So I would like to know if this is the case?
Howe to reset the flash read error to (0) zero it must somehow related to flash encryption or something else.
I double checked the hardware etc.
Like to hear.
Kind regards
Theo

ps I have the pyton esptools installed in arduino hardware folder and I am using the arduino ide for flashing my esp32

That's a great project, but when I power it with powerbank - it's ok, but when i try power it with samsung charger or ac/dc modules like these:

there's a big trouble. There's no sound or it's squashing

Please, help, how can I do it?

Hello,

After using the radio for a couple of day,s without problems I noticed a " as it looks like a refresh " problem.
On the display a line of text remains and it looks like text is displayed over a old text. See picture.
Stop and resume cleared the display and cont. with a correct text.
This phenonemom happened more frequent now.

As the display is also controled by the SPI and this looks a problem which came up after some time my idee is. Is there a relation with ths SD problem?
@ed, I just wants to let you know this phenonemom.
If I can do something please let me know hopefully I can help.
Regards,
Theo

Dear All
I want to share my modifications, that displays, IP , web radio name and title on a small OLED screen
#Esp32_radio_oled.zip

The ESP32 supports I2S, so why not use the I2S output to connect a Audio DAC like this one: https://www.aliexpress.com/item/Interface-I2S-PCM5102-DAC-Decoder-GY-PCM5102-I2S-Player-Module-For-Raspberry-Pi/32807703240.html

It is very cheap and will probably solve the noise issue as wel.

Another thing is, the ESP32 supports touch control. That could replace the mechanical controls.

I tried the ESP8266 version also, it is excellent.
I'd use the ESP32 verison now and I have some modules with built-in I2C OLED.
I have this one:
https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.6.2.v07Jjm&orderId=85346295631073&productId=32807483723

Unfortunately the number of exposed pins is minimal and stupid a bit. The PINs you used for SPI are not exposed.

The question: Can I use another set of SPI PINs (not the standard VSPI) in Arduino?
I tried:
SPI.begin(12,13,14); without success.

I checked the connections, seems to be OK.
Do you have any idea/advice?

Thank you.

George

Having trouble compiling.. It appears you added an include to a file called mp3play_html.h (presumably a new page for the web interface) 2 days ago, and loosely implemented it into the sketch, but I can't find it anywhere. Did you forget to upload it maybe? Or am I just blind? lol

sometimes after pressing "save" and then after a couples of seconds "restart" im getting:

I use an OLED display that has limited lifetime, so I implemented a screen saver function in the loop(). Within 1 minutes switches off. I use encoder, it switches back.

Hi, ED!!! is there any opportunity to add clock on display? there's a lot of empty space on display, i think it would seem great

Hi
Is it possible instead of 1053 to use Bluetooth BLE module of ESP32 to send the mp3 to a BT enabled device (speaker) which can play it?
thanks

Why some radio are not being found like
http://direct.franceinfo.fr/live/franceinfo-midfi.mp3

Hi Ed,

Already long time not contacted. The radio play,s very well.( we only suffer from a really slow internet) as soon as we surf on the internet the radio looses some bits. Not the problem of the radio KPN lack,s "buitengebied"interest.
This evening I checked the site and sow a new revision dated 19th July.
So I installed and tested it. I must say I have the impression it became less stable. And starts up quit a bit slower.
Now my experience,
The operational error direct noticed was the channel operation.
On my system I have gpio13 vol+ gpio14 vol- , gpio26 channel+, gpio27 channel-, and gpio25 preset6
It is not possible to operate the channel via the pushbuttons once you have channel for instance 5 it is not possible to lower the channel. It looks like the only way is up and remains there.
After some tests I noticed that only after you pressed the "control" on the html page banner it will lower the channel.
An other thing. OTA seems not working on my system.
I tested it with the arduino basic OTA script and this is working.
So with the radio script it is not?
Not a big deal but I would like to feel the luxure to program the radio over the air while the radio and the esp32 is build in in a nice case.( no external possibility for the usb connector.)
The time indicater is a nice feature. Howe ever it looks like it is not always shown on the display.
The lower indicater banner showed preset 8 but I have only 0 till 7 programmed?? This is 8 but still.

The serial monitor gives the following: after I pressed the gpio27 for request lower channel
( it has worked perfectly )

push gpio27 I did.
Serial monitor showed,
GPIO27 is now low , executed down preset =-1
command downpreset with parameter -1
preset is now 3
Stop request
Stopping client

( is it necessary to note -1 for downpreset? Volume is not like that it is just 2 for both up or down?
Like to hear.
ps. The radio is in our living-room operational. If the wife likes it it is ok. But if it has some unlogical hick-ups she will complain and I have to go to the shop I,am afraid.
We will see.
Kind regards,
Theo

radio does not connects to hidden SSID and then starts too run its own AP

One of the great improvements of ESP32 is the integrated bluetooth feature. For ESP-idf there is already an example for a a2dp sink (https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/a2dp_sink). I hope this will soon be available in the arduino esp32 as well. At that point I would appreciate to have it integrated in order to be able to connect a smartphone vie bluetooth and play the a2dp stream on my esp-radio.
