#ESP8266 ColorChord Driver
#ESP8266 ColorChord
Please see the main ws2812esp8266 project for help with setting up your environment and programming, etc.
(based off of ESP8266 I2S WS2812 Driver)
This project is based off of the I2S interface for the mp3 player found here:
https://github.com/espressif/esp8266_mp3_decoder/
If you want more information about the build environment, etc. You should
check out the regular WS2812 driver, found here: https://github.com/cnlohr/ws2812esp8266
WARNING: This subproject is very jankey! It's about stable, but I don't think it's quite there yet.
## Hardware Connection
Unfortunately the I2S Out (WS2812 in) pin is the same as RX1 (pin 25), which means if you are programming via the UART, it'll need to be unplugged any time you're testing. The positive side of this is that it is a pin that is exposed on most ESP8266 breakout boards.
The audio data is taken from TOUT, but must be kept between 0 and 1V.
