USAGE: ./elad-local frequency Sampler_code Central_frequency Attenuator+lowpass Sampling_rate

I/Q are sent to standard output

The samples are sent in packets as:
128 I+Q samples (32 bit floating)
1024 bytes


Attenuator+lowpass has the contant xy
where x is 1 for normal filter based on frequency 
      and x is 0 for no filter
and y id 1 for attenuator inserted
and y is 0 for no attenuator

if you omit the frequency elad-comms starts at 14.200 MHz

for usage with S1/S2 you have to run first elad-firmware that load the correct firmware on sampler.
