SpeedSpectra.

• Use json files, to control the device, with fields:
  • time - time duration of spectr in quants (one quant equal 50 milliseconds)
  • channels - list of channels values in range 300 - 4096 (for confident switching on of the diode, the minimum recommended value is 300)
• File format:

    "channels": [1540, 1293, 2647, 3954, 1697, 3059, 651, 383, 2300, 830, 2227, 1847, 3863, 3241, 2124, 347]

Starting application.

• Application takes two parameters:
  • Port "-p" - default use /dev/ttyUSB0
  • Json file with spectra and time "-s" - default ./spectra.json

$~ ./SpeedSpectra -p /dev/ttyUSB2 -s ./my_spectra.json
