New Firmware connects to Arduino by I2C
With only 3 wires now we can connect INDSP to Arduino.
More, in this way we have a 8 Band equalizer too.
Library is free for personal or commercial uses.
With Arduino we can control :
Noise reduction in steps of 1 dB (0 - 45 dB);
8 Band Equalizer in step of 1 dB (+-9 dB);
Select one of the 7 bandpass filters
Switch on/off the Auto Notch filter.
