| | RE: NXT external storage

| (...) Yes. RobotC already supports an optional "fast" mode that is five times faster transmission when reading a single byte. For reading multiple bytes from an I2C device, RobotC is about 15 times faster than the NXT-G firmware. There are a couple (...) (18 years ago, 9-Apr-07, to lugnet.robotics.nxt)

| | Re: NXC/NBC release news
|
| (...) The standard NXT firmware has a bug in the replace opcode which makes it impossible to use with multi-dimensional arrays (or ragged arrays of arrays). I have fixed this bug and submitted the code to folks at NI and LEGO for possible inclusion (...) (18 years ago, 30-Mar-07, to lugnet.robotics)

| | RE: IR Problems
|
| Elizabeth is quite right. It's easy to get collisions on the IR "bus" if two devices are sending (or replying) simultaneously. What I've done in the past with two RCXs is define one RCX as primary that is periodically (every 100 to 250 milliseconds (...) (18 years ago, 2-Apr-07, to lugnet.robotics.rcx)

| | 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)
