How TransmitIrRemoteButtons.bs2 Works
The
below.
remoteCode.BIT7 = 1
always is for SONY TV messages. Then, it pauses for 23 ms. This, plus the processing
time for the
PULSOUT tPIn, 1200
calculates and sends the pulses of the correct durations for binary-1 and 0. For example,
if
300
remoteCode.BIT3
lasts 0.6 ms, which transmits a binary-0 pulse.
' Change button values to remote codes.
IF (remoteCode = 0) THEN remoteCode = 10
IF (remoteCode <= 10) THEN remoteCode = remoteCode - 1

RETURN
remoteCode.BIT3
sends a
Send_Ir_Remote_Code
It sets tPin (P6) low to turn off the 555 timer's signal.
READ
PULSOUT
commands causes a typical message to repeat every 45 ms. After that,
is 0, then the
is 1, the command
of 600, which is 1.2 ms, which is a binary 1 pulse. However, if
sends the start pulse. Next, a series of
sets bit-7 in the remote code variable to 1, which is what it
subroutine in TransmitIrRemoteButtons.bs2 is shown
PULSOUT
PULSOUT tPin
command only sends a pulse of 300, which
