And yes, it uses virtual devices. A friend sent me a link to this page- <https://www.bartnec...EU-FA9e10> The page gives a walkthru to set up a virtual device, install XP in that virtual device and then spool up the RCX software and the IR tower I (...)

I've used the RCX with standard LEGO firmware, though I'm not familiar with the Swan firmware. Having said that, this simply sounds like the old message is not getting cleared to make room for the new message. Have you tried calling the (...) (6 years ago, 18-Jun-18, to lugnet.robotics.rcx)

Good morning We are using a total of 12 lego rcx sets to practice in an educational center. We are using the nqc language with these robots. We use 2 types of firmware: on the one hand the firm0328.lgo, sometimes the firm0332.lgo, ie RCX2, and also (...) (7 years ago, 1-May-17, to lugnet.robotics.rcx)

(...) D'oh... I'm posting this because I'm sure I'm not the only one who missed this: I didn't realize there's a drop-down when BricxCC starts up, to select "Swan" instead of "RCX" when making the first handshake with the brick. After doing that, it (...) (12 years ago, 19-Jul-12, to lugnet.robotics.rcx)

Hi all, One of the common ways I like to control the speed of a gearmotor (in NQC) is by introducing a loop, for example, like this: while(true) { OnFwd(motor); Wait(a); Off(motor); Wait(b); } I often do this as a motor approaches a setpoint (say an (...)
