normal component 0402 or 0201

It can be assumed that all component sizes are normal. However, not everyone can grasp the 0805 components let alone the 0102. And there is no exaggeration here

Are you sure this is a jumper ?

No. I was following up on a thread by kol. @amrowek
Maybe he can identify the item .

Disable the SD_LED in the definition and replace it to have a SW_POWER button on pin 17

I have no such SD_LED definition

Apparently it is missing. The Power key works, but only turns on the radio. I checked that when it connects to the ADC keypad button it doesn't introduce any interference and then the power key works both ways (turns the radio on and off)

But unfortunately my Standby LED doesn't work in the reverse option, ie LOW when switched off, HIGH when switched on.

I flooded these three pads

Well, I did a 2-in-1 I shorted both antennas

This 'jumper' for switching antennas on the ESP module is a resistor marked R16 and is about 3ohm. I have personally checked.

@efi222 i.e. it's not a jumper and it might as well be a coil. You need to solder connect an RLC bridge at 1kHz and at 10kHz check the reading.

@dawidkosciesza I think I added the LED_SD option later and this version is not yet on GitHub it is with me as RC (Release Candidate)
Such a bit of a prosthesis once to call power OFF by remote control command and wake up by pin but since it works properly it's most important

The reverse LED configuration doesn't work properly because doing a power ON calls a reset and this resets the GPIO registers. You need to, after a correct start, set yourself a high state in setup() which will be disabled in powerOFF and that's it.

Hello,
i have uploaded on GitHub the new soft 3.19.52, what's new ?

PLAY FROM URL
There is now a new PLAY URL button in the menu, which allows you to open a page where you can test any stream from the Internet on the radio after entering an external link. I am not hiding the fact that this is how I test various interesting stations added by other colleagues creating Internet radios.



Start logo
I have added options to add your own logo instead of notes. The program itself checks if you have your own logo on the SD card or in the SPIFFS memory, if so it will be displayed instead of the notes. How does this work? You need to create a logo in XBM format (e.g. using the free Gimp) with a resolution of 256x64px as a black and white 1-bit image. Save such a file under the name logo.xbm on your card or in SPIFFS memory and that's it. Just remember that above the logo, after 1 second, the text "Evo Internet Radio" will appear, so that someone who sees the radio at your place can reach the source of this radio and in the bottom line there will be information about the connection to WiFi and the IP and software version.



WIFI MANAGER
I have improved the mode of connecting to WiFi a bit. From now on, if you connect correctly, a large CONNECTED message will appear on the display for a moment, the IP number and the radio will reset itself.



CONFIGURATION
Two new options have appeared in the settings.
The first:
"Save ALWAYS Station No., Bank No., Volume" its deactivation will cause the radio to save the value of volume, last station and bank to memory only when "powerOFF" is switched off. This is to prevent excessive memory usage especially SPIFFS.

Second option:
There is an option to set yourself your timezone, it is stored in the timezone.txt file, in the case of Poland you don't have to do anything, the radio in the absence of detecting this file will create it itself the first time and store our timezone there. This is a nod to colleagues outside of our time zone so that they can change this in the configuration.




VU-indicator - mode 4
In mode 4 (analogue drive indicators) when you press the DIRECT/OK button on the remote control, 10 rectangles will appear between the indicators, each indicating 1 second of audio buffer fill. In other words, this is a quick overview of how much data a given Icecast station/server allows to buffer. This is calculated in a simple way the buffer content in kb is divided by (BITRATE / 8). The result of course depends on the correct bitrate of the station. Those which have a fixed (frequency (44.1) * channels(2) * resolution(16) i.e. 1 411 200kbps) will show an incorrect buffer value.



VU METER - mode 0
I've added a mapping to VUmeterMode0 to eliminate clipping but I have a feeling this is a problem with the mp3 decoder, which outputs a uint16_t variable and sometimes gets overflow, so when split into two 8 bit values one may have a mismatched value in a given frame loop.


SKETCH
From now on in the sketch itself at the top under the header I will include information about the libraries used for compilation



SPACE
As you know "without LED you won't sell" so I added some LED type outputs - STANDBY_LED on GPIO16 and SD_CS which can be "pinned" on GPIO17
Of particular interest is the SD_LED signal, which is cloned by the GPIO matrix in ESP from the Chip Select (CS) pin of the SD card reader when the SD card is defined and used. This way we are not physically pulling the CS signal on the board and at the same time we can keep track of SD card activity especially if we are using the SD card reader that is on the Evo board at the back of the chassis. Pins 16 and 17 are no coincidence as those who have a board made for the MajstraXXL v2 or Evo schematic have them routed to the Joystick connector.


TALKS
As I've already written, I sometimes "peep" at others to see what they're creating because it's always inspiring, and on the website of my friend JCS I found an interesting program called AirMusic for Android phones. It is an application that allows you to make your phone into an Icecast server and e.g. stream any audio you play on your phone to your radio: YT, Spotify, mp3, microphone. Useful e.g. when testing spectrum analyser.



I have placed the HTML code for both PlayURL and Timezone in the INO code. It's not the happiest solution, it's easier to edit and keep it as html on the SD card but on the other hand for someone new one file to compile gives basically a finished solution.

I am attaching two example logo files. They are not on GitHub and are included here as a reference on how to create such a logo and not as part of the Evo radio.
For such a logo to work you need to rename it to "logo.xbm".

>>21773883 super changes, this project is developing at a dizzying pace. I'm testing and from comments, I noticed that there are streams that work for example on a computer in the browser, on other audio librariesI2S also (yoradio), and here not. This problem was already present in previous versions of the software, but I did not report the problem.

For example, Radio Kwidzyn (but there are also several other stations):


The second thing I have noticed is the pointer VU - mode 4 - there are no vertical rectangles with me.

I uploaded the .bin for myself via OTA, I did not test uploading from sketch

@Lechuuu address https://s3.slotex.pl/shoutcast/7308/stream?sid=1 has a redirect in the library to https://s3.slotex.pl:7308/stream/1/?sid=1 I don't know why the radio, despite seeing the new link correctly, doesn't open it but closes it with the message stream title: HTTP/1.1 404 Not Found but when you type in the new one it plays correctly - Radio Kwidzyn.
I opened a thread at Wolle's (author of the audio library) why the redirect didn't work correctly despite the correct link.

In Mode 4 you have to press DIRECT/OK (the button assigned to "rcCmdDirect") to enable the buffer preview. Normally the buffer information will not be displayed to you. It is only there if you request it.

Well I scored a gaff - yes I read the posts, it actually works.

Well the stream works too, thanks.

From the cycle of what was played..., someone on the forum earlier suggested the idea of logging events so I sat down to the topic to make an event.txt file on the SD card where the data of the current station and the material played is stored with an assigned time stamp. The lines won't be saved indefinitely but in a limited range, for now I've given 10 entries to start with, the oldest ones fly out and the new ones at the end of the list. When I polish the code a bit with descriptions, I will upload it to my github profile, it will be on me at version v3.
Later I will add a call of this log to the radio screen using another new remote control button "Search" with the option to scroll with the up and down arrows.

And this is how it looks on the serial:

>>21774134 Master a cool tale. I think I will also get something like this in the Evo
By the way I had an adventure with radio in my life the software did its log exactly on this principle (and it was Dyna to this day very popular radio software used for example: by RMF) and audio copies were made.... note here hit on videotape in LP mode because it gave 6h recordings so only 4 tapes per day

Any reference of the audio library to evt supports you logs or do you filter it even harder ?

@Lechuuu Radio Kwidzyn has been added to Bank03 - Cities, it is at number 53.

>>21774145 I simply wait for the new data to appear in the "displayRadio" function and there at the very end I threw in this event logging:

>>21774161 In my displayRadio is not called every time the StreamTitle changes because it is handled by TextScroller but I get the principle so you have already given me an idea how to add it. By the way, I just added the save to SD card to add the LOG now, thank you

Hello, I am having trouble with a display. I have a SSD1322 display, I am looking at the schematic and the display instructions. I can't seem to identify the pins and what and where they should be connected. Can someone enlighten me a bit?

>>21774260 Take a peek here https://europe1.discourse-cdn.com/arduino/opt...d824d880e37e8ef8541270d44d533b4_2_543x500.png

Thanks. It's already clear.

With me now, no logo is displayed.

There was another byte there, but as far as I remember the Author of the code is not planning an "Add to favourites" byte.

@hevet a did you win a memory file with the logo ?

I haven't uploaded, but you wrote that if I want mine you have to upload to memory, otherwise it's default.

>>21774301 there should be notes...I'll have a look at it later.

Hello.
I have this problem even with the test file.

@robgold When compiling the latest software, this error pops up:

This is probably the fault of the ESP Async WebServer library version 3.9.1, because when I change to 3.7.2 everything compiles beautifully.

>>21774349 And did you delete sketch (the folder where Arduino keeps the pre-compiled parts of the project) ?

In my radio works on
ESP Async WebServer: 3.9.1
Async TCP: 3.4.9

It compiles without any problems. When picking up AsyncWeb, you need to pick up the ASyncTCP revisions. This goes hand in hand with.

@hevet I checked and correctly notes appear at startup.

@robgold Now it's compiling. Blind me didn't update the Async TCP😀.
Thanks.

Start logo test video.

@robgold then I have a problem, the logo only displays when I upload it to memory, otherwise black screen at the start.

>>21774502 @hevet
please find ino this function and replace it. Apparently the SPIFFS memory can return "true" even if the file has a length of 0. You should have created traps. Somehow I missed that with the SPIFFS memory.

@robgold is fine, the logo is back .

Greetings. Can such a card reader be used? It has slightly different markings. It already has resistors on it.
