ESP32 Internet Radio TTGO T-Display board

[@threedaymonk]

What a great project! These little boards seem amazing value, but I had no idea they could manage something as complex and processing-intensive as this. It sounds much better than I expected 8 bit audio would.

[@smitmachinale8281]

Watching your esp32 video's, i have also catched the esp32 fever. Thank you🙃

[@VolosProjects]

Tnx, your welcome😀

[@richieraisz9353]

It seems my previous comment was deleted.... maybe because the attached link. So thanks for sharing, this works fine, and there is no problem to upload the sketch. It is a very useful project for me, there are some stations here, available just via net. Let me suggest / kindly ask for a development of the project. It would be very useful to include a web server, enabling an easy way to enter wifi credentials. In this way the project would be really universal, and mobile, enabling to take the device with you, connect, and use anywhere. I guess, most of us would be grateful for this functionality! Thank you to take my comment into consideration, and many thanks for developing, and sharing this project!!!

[@0miker0]

Huge thank you for posting these projects and releasing the sketch that we all can use. I created a desktop clock/ weather station that uses pieces of your code and could not have done it without your help. Please keep up the great work.

Hi! I follow your projects with interest. The videos are both educational and entertaining. Maybe one day you can show how to make an interface that controls rgb leds(ws2812b). This can be done via the internet, but it would be nice to do something like a color picker from the TTGO T-DISPLAY's screen. Thanks for this cool video.

[@VolosProjects]

Not bad idea,thank you 😃

Damn, I overpaid by 3 euro I just checked. Bought it in December 2019 it seems and has been in the famous drawer since. Our friend here made me take it out again. Now I need extra glasses to read the display.

[@DanielSMatthews]

That is very smart, I was thinking of adding a unit like that to an old portable radio so that I can have information services and server processes post messages via MQTT then use Larynx TTS to feed the messages to an announcement service. One way is to have the TTS output to a wave on a HTTP server then send the URL to the TTGO board so that it just sits their playing new waves off the server whenever it is notified of a new one. It would just have to maintain a small queue of URLS in case the messages came in faster than it could play the audio.

[@mrobarton7192]

Another great video! I did not see in the code TFT_ BL (pin 4) defined. I assume it's done in the user setup header file. Also there is an LED included perhaps for future use? In the video it appears to be a SPST slide switch are you currently using that in this project? Again another great job keep up the good work!

great project. can you add bluetooth pair output. that would be ultracool

[@ugetridofit]

Now take it to the next level and have it connect to a bluetooth speaker.

[@Luke-san]

I don't think that they have a protocol to stream audio over BT. I requested the same in some KAradio groups and nobody answered. My advice for now is a Pi Zero W and Moode player which works perfect with BT speakers. I have a Zero 2 W also but that one has an issue sending audio to BT with moode.

. Great project. You have 2 radio projects. 1 FM and 1 internet. How about combining them so we have FM reception and also internet and if we add Bluetooth probably we can stream playlists. Any feedback or advice on hw and libraries to use? You neighbor from Greece where internet sucks sometimes

I really like your Internet Radio project, But I only have one question. Without a schematic to use, I took a screen shot of your project board to better understand where the extra button and slide switch was wired. After reviewing your sketch file I see that BTND=17 but in the video I don't see where this GPIO pin is being used. What am I missing. Any help you can give would be greatly appreciated. Thanks again for your videos they are very helpful for a beginner like myself.

Thank you for sharing your design. I really like the display. Since RECEIVA is closing down, my Crane Internet radio will soon stop working (search has already stopped) and I plan to gut it and replace the insides with something like what you have designed. My goal is to use the CCWIFI's original knobs and buttons.

[@brentjohnson1784]

I want to do exactly the same thing, if you figure out how to use the original knobs and buttons - please let us know how you did it.

[@lakyljuk]

Which version of board do you recommend? There are 3 types available at Banggood link you provided - different memory, different transfer speed, what is better?

[@michealmorrow1481]

So many questions left unanswered! What pins are you using for output (I see in comments). Are you driving a speaker directly or an amplifier? What amplifier or what kind. Where did you get that breadboard mini-phono connector?

[@user-sb5jb2cn9d]

you write "connected to pins 26 and GND" which is the audio output pin26 (Dac2). is the pin25(Dac1) also audio output? stereo output? And which pin is the button connected to? Pin 12 or 13

Do you think you can combine FM and internet Radio? in one, I saw you have another project with fm Radio.

[@mangeshgaikwad345]

Yosome 🤟

[@zaprodk]

Very well thought out! - Did you think about adding some code that doesn't start playing the audio until the buffer starts changing (to avoid the Bzzzzzzt sound on playback start)? - I guess you could check the audio buffer for changes before enabling audio output simply?

[@MickesSg]

I think the blocking "delay" commands int the main loop causes the problem.

[@eddyleast8684]

Found this on the audio library he uses // AudioOutputULP out = new AudioOutputULP(); // stereo // Connect left channel on pin 25 // Connect right channel on pin 26 // OR // Connect mono channel on either of them (stereo samples are downmixed) // AudioOutputULP out = new AudioOutputULP(1); // mono, only DAC 1 // OR // AudioOutputULP out = new AudioOutputULP(2); // mono, only DAC 2 Although I dont know how to implement it, since he's using I2S and not ULP. its on the AudioOutputULP.h at the src folder of the ESP8266Audio Library

I hate to be even slightly critical since I think ALL your Volos Projects are Very cool.... but I know I'd really struggle building some of them without a schematic and simple parts list with Part Numbers.. When you place components around the edge of the dev board, and don't give us any info on what pins need to be wired to them, or the value of the Potentiometer that may be needed, or how to wire the Audio Jack, or rotary encoder etc.. and also fail to give us a photo or view of the BACK side of the project anywhere in the video .. I get very discouraged knowing it may be very hard to figure that stuff out.. You always make downloading and using your excellent code VERY easy .. But the hardware and hookup needed can be very hard to replicate.. BUT, If you could please just add a simple photo of a hand-drawn schematic to the project's GIT Hub repository that would solve the problem several others have commented on below. I really do want to make this Internet Radio but have no idea how to wire its switches, jack and pot..

You just need to slow down. Sorry, my chanell is not step by step, this video whod need 1 hour if i will explain every time that i explain how to wire pot as resistor on some pin.

[@jimsnodgrass8454]

@@VolosProjects I understand and agree you can't waste time. But others have commented on having the same problem (below). We simply want to know a litte bit about the hookup and types&values of components needed. Usually a very simple uven hand-drawn schematic or photo would solve it... If you could just flip the board over for a second or two during the video we might be able to figure out and hand-draw out the schematic on our own.. I have tried this and it can take hours too. Please consider parts like potentiometers come in about 10 different Standard resistance values. Should we just guess? I just ( for example) ordered 4 different value POTS cause I'm trying to build your Color Picker PCBWay Board because you never tell us what value pots are needed. I really want you to succeed. I'm just spoiled I guess by most other YT channels which do document projects a little bit better i guess. Oh well ..
