esp32 wireless display for moOde, at only $5?

[rix81]

there are various inexpensive esp32 based displays on aliexpress,  starting from $5.27   with built in esp32  (check bundle deals)
I'm not familiar with this, but is there a way to use them as wireless display for moode?  At least to show mdp info,   or to get basic controls like switching internet radiostations etc.

Sounds like a great DIY project for someone, what my dad used to call “a learning experience”

However, once you start adding up all the other stuff you need—-powering it, encasing it, learning how to program it, developing a communication protocol between it and your moOde player, etc.—-you’ll see the appeal of the official 7-in touch screen. At least I did.

https://github.com/dheijl/M5PaperMpdCli does something similar.

I was hoping that someone already did it. My knowledge of programing is zero, but chatgpt swears that it(he) will provide me working code. Hmmm.... doubt.
I'm going to buy this display. And then will see,

dheijl - interesting, sadly it's only text ui

dheijl - interesting,  sadly it's only text ui

I hate Gui programming, and will go to great lengths to avoid it...

my display was delivered.
chatgpt was able to generate code to display current station and song,   but with only with text ui.    he can't do Gui properly (

Hi, 

I used this project as a template and recreated it with modifications (using ESP01 with serial data-connection instead of parallel, etc). Working fine. Probably a good starting point. Thanks to Github-User nopnop2002.

I made another one with a beautiful VFD. Here is a video.

Hello everyone,


the delivery of the MAX7219 modules arrived. I have connected six pieces 32x8 dot matrix modules together (~80cm length) and control them via an ESP32-C3. (The MAX7219 looks awsome) Instead of contacting the MPD directly, I used the moOdeaudio LCD updater this time. I was very lazy and used Tasmota instead of my own sketch. Data exchange takes place via MQTT. I don't know the Python syntax well, so improvements are welcome. (In particular, sending the MQTT message should be done directly via Python, not via Bash commands.)
