ESP32 Forum

Most of the programmers here might be a few paygrades above this level of introductory stuff, but you might still find it entertaining. A full code review of an ESP32 single-chip spectrum analyzer.

Beyond DAC setup, covers interrupts, timers, multicore processing, the FreeRTOS scheduler, scheduling tasks, idle loops, and so on.

Hope you like it, let me know either way! There are 3 parts to it, here's the first (below). It's in VisualCode as the IDE, but all ESP32.

Thanks for sharing!!!
This is exactly what I have wanted to do for a while now. So glad you posted it.

PS. Dave, you share the code source for that project, and get into the hardware side of it too ?

I was thinking of maybe doing a Kickstarter to see if there's any demand for them, and if not, then I'd release the code. I show 99% of the code in the video, so there aren't any secrets left anyway I guess!

Well, when you have made a decision let us know.
