A tiny display would be cool, and maybe useful once people get used to the idea
of a spectrum analyzer that doesn't have to roll around on a cart.
Me, I'd be very happy just to have something cheap that works well.
If I'm serious about making a measurement, I want to save the data to a file anyway.
Would much prefer Linux based software, an RPi would be ideal.?
An RPi-Zero is $5, can save files, displays to anything from a
cheap 3" SPI LCD to a 1080p HDMI monitor,
Can host its own software build environment.
And it can drive the SPI bus into the SI4432's, no need for an Arduino.?
