rfscanner

Simply outputs all received signals:

Usage: rfscanner [options]
Options:
  -p <number>, --pin <number>   The input (wiringPi) pin number (see http://pinout.xyz
                                for details, default: 2)

rfrecorder

Looks for a pattern in received signals and stores it in a file.

Usage: rfrecorder [options]
Options:
  -o <path>, --output <path>    Specifies the output file path
  -p <number>, --pin <number>   The input (wiringPi) pin number (see http://pinout.xyz

  --buffer-size <size>          The size of the input buffer (default: 250)
  --record-samples <samples>    The number of samples recorded (default: 5)
  --record-failures <count>     The number of samples not matching previous samples
                                before discarding all previous samples (default: 2)

rfplayer

Plays a file created by rfrecorder

Usage: rfplayer <filename> [options]
Options:
  -p <number>, --pin <number>   The input (wiringPi) pin number (see http://pinout.xyz
                                for details, default: 0)
