Hi All. I've just had some wierdness with my tower and decided to open it up to see what's inside. My basic issue is that the two emitters and the detector are not lined up (even close) with the "Clear" lens section on the front of the tower. Is (...)

(...) I'll back you up on this. My pbFORTH sends a simple character stream and it seems to work fine. No complements are necessary. 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)

Hi all, I've been using Legos without any major problems but never got the tm-and-ir demo to work properly. I can receive characters on the RCX fine but when the 'view' button is pressed (within 3 seconds) the results are normally junk on the screen (...)

(...) So of course I was curious about getting rid of the complements. Apparently, they are not necessary, or so my testing so far seems to indicate. 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 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)

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)

Sorry, I have been out of the loop for quite some time now on the protocol.

(...) you can specify where the .h files are using the -I switch... maybe you just need to check the Makefile (or Makefile.common) and change some paths there... or: check the configuration of compiler, sorry, I can't help with that... erik (25 years ago, 5-Jun-99, to lugnet.robotics.rcx.legos)
