I won't mind if you tidy up the arduino code and post an updated version....
These are the commands used by the PC SW for the tiny spectrum analyzer:?
v : select VFO
o: set output frequency
a: start of scan
b: end of scan
m: scan once
t: step time
w: RBW
s: steps
x: read/write SI4432 registers (very usefull in Arduino monitor when experimenting with the SI4432)
