John, I have a few beginner questions for you. I am trying to emulate the
infrared protocol on a different microcontroller. I want it to be able to be
controlled by a Lego remote and to send/receive messages to Lego devices. What
format does the Lego Remote protocol has? My microcontroller can do a standard
protocol like 8 bit command followed by 8 bit device. Is this close enough? The
device is the RCX, Spybot, Remote, etc. and the command is 01 to 99 or whatever
else? Is there a list of commands and device codes that I can use?

Thanks for your patience, the result of this study will be posted soon.
