|
| I can't figure out how to use the IR commands. I've tried, read a bit in the documentation, but still have no clue. I'd like to know how to: a) Send a message (and decide what message it should be) and b) learn how to recieve messages Thanks in (...) (24 years ago, 29-Mar-01, to lugnet.robotics.rcx.nqc)

| The tower is just a serial device! No driver (other than that supplied by Win2K) needed! You can also use NQC to program your brick, or order RoboLab ($25) from Pitsco (www.pldstore.com).

Put your send-zero loop in a separate thread and I think you should be set. (24 years ago, 27-Mar-01, to lugnet.robotics.rcx.legos)
