/*
Usage: ./codesend decimalcode [protocol] [pulselength]
decimalcode - As decoded by RFSniffer
protocol - According to rc-switch definitions
pulselength - pulselength in microseconds
'codesend' hacked from 'send' by @justy
- The provided rc_switch 'send' command uses the form systemCode, unitCode, command
which is not suitable for our purposes. Instead, we call
send(code, length); // where length is always 24 and code is simply the code
we find using the RF_sniffer.ino Arduino sketch.
(Use RF_Sniffer.ino to check that RF signals are being produced by the RPi's transmitter
or your remote control)
