For the moment not much. You have some basic key control of the power
scale with the keys.
But that's the next item in the TODO list :
- Proper frequency scale with set_center_freq / set_sample_rate
- Click to tune call back
- Cursors
Waterfall rate is probably going to be later. There is currently a 1:1
ration between each FFT computed and each line of the waterfall
texture.
Since the whole idea being fosphor is to never just "drop" data, to
slow down the waterfall, multiple FFT results must be "aggregated"
with either min/max/avg functions and that's a bit more tricky to
implement.
Cheers,
Sylvain
