You should have either tired to build the cross compiler or downloaded it (...) (22 years ago, 9-Dec-02, to lugnet.robotics.rcx.legos)

| | RE: IR Problems
|
| RCX IR does not require direct line of sight. All sorts of reflections will work. Especially if you're in a "smallish" (bedroom, home office) room. The RCX firmware always has the IR turned off. "Wait for mail" and "send mail" is just a higher (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

When I send a 0xf7 opcode with a message of 0x03 (...) (21 years ago, 3-Feb-04, to lugnet.robotics.rcx)

The sender should be programmed to handle message loss. What I had the kids done was (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)
