adding a vu-meter with LEDs #169

Closed hmax42 closed 3 years ago

hmax42 commented 3 years ago

Hello First, thank you for this great project.

I am already using it successfully with the Make Python Audio 2.0 https://www.tindie.com/products/makerfabs/esp32-audio-player/

Now i want to use it with Pimoroni's Speaker Phat and Waveshare's ESP32 One https://pinout.xyz/pinout/speaker_phat https://www.waveshare.com/wiki/ESP32_One

Audio works :) But i'd like to put the current volume of the sound into the LEDs. The LEDs are controlled with a SN3218 so that works. But how can i find out, which LEDs to light up according to the current playing sound? How can i access the wave data?

https://github.com/hmax42/ESP32-audioI2S/commit/6cce84217e5bc8f2f8925936affc84576932a29b have to test it still, my local dev env uses my branch "powerlevel", which uses a ESP32-audioi2s-version from last summer and an esp32-1.0.4
