// Quick and dirty tool to decode mode2 data from LIRC
|
|
// Copyright 2018 Brett T. Warden
|
|
// based on c2_decode.cpp, Copyright 2017 Jorge Cisneros
|
|
|
|
// Usage example:
|
|
// mode2 -H udp -d 5000 | ./mode2_decode
|
|

/* Sample input (alternating space and pulse durations in microseconds):
|
|
space 500000

pulse 915
