int SendOldElroBit

(

int

Bit

)

Send a bit of an OldElro RF code with the correct timing.

Send a bit with the OldElro encoding

• The datagrams are rather simple, the first 4 bits are the house code (A-P).
• (LSB first, 1000 = 0x01, 0001 = 0x08)
• The second 4 bits are the device code (1-16).
• (LSB first, 1000 = 0x01, 0001 = 0x08)
• And the last 4 bits are the action (on/off/blink/dimtoggle/powertoggle):
• Action
• 0000 = ???
• 0001 = ???
• 0010 = ???
• 0011 = OFF
• 0100 = ???
• 0101 = ???
• 0110 = PWR TOGGLE
• 0111 = DIM TOGGLE
• 1000 = ???
• 1001 = ???
• 1010 = BLINK
• 1011 = ???
• 1100 = ON
• 1101 = ???
• 1110 = ???
• 1111 = ???
• In the encoding every bit seem to have a preamble,
• in which the transmitter is turned on for 1 period and turned off for 3 periods
• a Zero consists of turning the transmitter on for
• 1 period, turn it of for 3 periods.
• A One is turning the transmitter on for 3 periods and turn it off for 1 period,
• So a Zero is 1-3-1-3 and a One 1-3-3-1.
• The first 1-3 seems to be a preamble.

• Parameters

  Bit	( 0 or 1 )

• Returns

  zero on succes and a negative number on failure
