This is in reference to a problem I am having programming the internal
IR of the Palm device but the information I need is about the LEGO IR
tower so I am posting it here.
It is my understanding that the LEGO IR tower does a direct conversion
of serial data to IR pulses. I mean, sense the IR tower uses a null
modem cable to connect to the serial port, I thought that the tower
simply converted the high and low voltage to on and off IR pulses
respectively. Is this correct? Is it adding signal information? Does it
invert bit polarity (0 bit = on)?
Any insights or speculation would be helpful.
