Hello, As a new member to Lugnet and to the RCX I am looking for some information on how to control pneumatic circuits using the RCX. I do not want to try modifying any brick or buying non-Lego pieces. Are there any good web sites on controlling (...) (23 years ago, 21-May-02, to lugnet.robotics)

| | LegOS, lnpd, and networking
|
|
It seems to me that a lot of the discussion lately has been on networking multiple IR (infrared) clients using legOS. Is the IR tower using an ID? This would identify messages from the IR vs an RCX. Also could the addressing be extended to allow IP (...) (23 years ago, 21-May-02, to lugnet.robotics.rcx.legos)

I've experimented with a couple of choices which were relatively easy to implement. Let me know if we should keep any these: 1. You can choose to set the host address at build time with a command-line option to make. Example: make LNP_HOSTADDR=2 (...) (23 years ago, 20-May-02, to lugnet.robotics.rcx.legos)

I get this error - "main() not defined" - when compiling. The code is copied straight from the Ferrari book. While C is the language of my choice, the line of code isn't so obtuse as to hide errors from me. So probably there is some other requisite (...) (23 years ago, 20-May-02, to lugnet.robotics.rcx.nqc)

The buttons "1", "2" & "3" send a IR message to the RCX. The RCX must be running a program that will respond to one or more of those messages. The A, B, C buttons will activate the RCX outputs forward or reverse. This requires only the installed (...) (23 years ago, 20-May-02, to lugnet.robotics)
