    Spectrum analyser Equalizer project how to go about it?

    sorry to repost I don't want the message to get lost in the comments history and kinda need some info thanks anybody have any ideas about charlieplexing and multiplexing with the esp32 and the 20 pins I need for the 320 LED's I'm using in my LED matrix which I'm making, and the FFT stuff...

    Spectrum analyser Equalizer project how to go about it?

    I have a fair few arduino's lying around, esp32's 4, nano's, 1 mega, 1 due, uno's tons of resistors 1/2 watt 1/4 watt, pots diodes zeners big ones small ones tons of caps - all shapes and sizes, wire and an annex iron, protoboard and lots of it transformers switches FET's tansistors bassically...

    I see, panic over! anybody have any ideas about charlieplexing and multiplexing with the esp32 and the 20 pins I need for the 320 LED's I'm using in my LED matrix which I'm making, and the FFT stuff, including that code that I posted ealier, with all the components that I may come accross and...

    when I click the maker pro logo it it messes things up even if I log out and in, but from this window that I'm on now I can right click my M logo and everything works fine

    Spectrum analyser Equalizer project how to go about it?

    So I've been tooking at charlieplexing and with 24 pins I can drive 520 LED's and what's more the esp32 dev board has 25 GPIO pins so I think this is what I'll be using because the code I have fits on the esp32, but I think it needs to be tweaked for my purpose, any ideas? the code I want to...

    So I get the multiplexing theory, how do I then have the LED matrix move to the music?

    Spectrum analyser Equalizer project how to go about it?

    maybe with the use of shift register - I don't know I want to use my mega because it has the 36 digital pins available, really new to these things and may take time to fully understand but I learn well and I've got the time so...

    I kind of get it is there any way you can tell me how to actually do this, by example for my 16 band 20 led high please?

    Spectrum analyser Equalizer project how to go about it?

    Ok understood, so how then do you go about making the columb and the lights in that column turn on at the same time before moving to the next column whilst in time with music "dancing" on the LED matrix?

    Spectrum analyser Equalizer project how to go about it?

    ok so if I were using multiplexing how do I make FFT and the frequency business and esp32 or the mega I need 16 x 20 equal to 36 pins which is achievable on the mega and I have one of those too
