ESP32 Spectrum Analyzer I wrote for the M5Stack connected to a Macbook for flashing.

I'm so happy I also found ESP-IDF after having a few false starts with the toylike Arduino IDE. Getting to use a proper IDE while coding for ESP32's has been such a boon. Ported my 3D game engine and wrote a 30fps 416x240 MJPEG video player for it since

@M5Stack Music is on brand for Dave even if I don't know what it is.

You never stop! Dave, as you are an expert and an excellent programmer, is it possible to port an older version of BSD to the ESP32?

Interesting... I'd think you could get 211BSD running. There's enough address space that you could just remove all of the linker paging and compile it to a flat binary, I think. I've just never enjoyed debugging the ESP32 very much and this seems like a case where you'd want a good debugger.

@M5Stack Esp32s are brilliant 🤗

I guess your brain needs to be perpetually tickled to keep it grounded? Like men like to walk back and forth while talking on the phone.

so i see you're using a fourier transform to extract the frequencies into a bar-graph. what would be superb as a visualizer would be full-screen frequency history over time — scrolling along a couple pixels per second — basically a history of the frequencies of the bar graph ✨

I asked Grok to ID the music in the video and Grok says it appears to be "Hungarian Dance No. 5" by Johannes Brahms. This piece is a well-known classical composition often used in various media due to its lively and recognizable melody. The specific arrangement or performance might vary, but the core theme is unmistakable.

Beautiful. Love the high FPS. Bychance did you put it up on github....

Are you human?

Looks super cool!

Yay!!! Nice job, sir!!!

Sweet dude

I really enjoy a lot of your little projects like this, I’d like to know how you find the hardware, I’m trying to do something similar with the cm5 lights

Nice. I wrote one too, but mine is slower and uglier

Nice post Dave. Two great Dave's in one, Plummer and Lindley.

Love his take on that song!

As you usually don't react in personal comments: I like it anyway.

I don't often revisit them, but did today, so thanks!

Thanks 😅. I really love, what you are doing.

When a bit of information values more than (kMG)bytes. Think atomic and evolution comes naturally.

Cool.
