I am trying this new project to create a spectrum analyzer using a 16x2 serialLCD from sparkfun (ADM1602U).

I have been working under the guidance of FFT: Fun with Fourier Transforms on adafruit and was hoping for more guidance in terms of displaying it on the SerialLCD and not using the NeoPixel library.

Are there any libraries out there to configure the teensy to a SerialLCD? Which part of the code would I have to remove or add on?

Thanks for your comments
