| | | | Regarding the IR protocol, I have elsewhere suggested the following simple low-level format: 1 start, 1 stop, 2400 baud, odd parity 55 f0 f0 L ~L D1 ~D1 .. Dn ~Dn C ~C L is number of data bytes, valid range 1..255, less depending on buffer sizes Dx (...) (25 years ago, 6-Jun-99, to lugnet.robotics.rcx.legos, lugnet.robotics)

I haven't done any testing regarding this, so I don't know how many zeros in a row will break (...) (25 years ago, 6-Jun-99, to lugnet.robotics.rcx.legos, lugnet.robotics)

Under the several lighting conditions I tried, and for distances of up to 27' (the farthest I could (...) (25 years ago, 6-Jun-99, to lugnet.robotics.rcx.legos, lugnet.robotics)

I sure would like to be able to keep the RCX tower alive, though. I wonder if it's the character going through that (...) (25 years ago, 7-Jun-99, to lugnet.robotics.rcx.legos, lugnet.robotics)
