 | | NXT model instructions under OS X 10.2.8?

My laptop can only run Mac OS X 10.2.8, but the NXT software requires 10.3 or later. And yes, I tried it anyway, but it crashes on launch. My desktop machine runs 10.4.9 and the NXT software works just fine, but I can't have my son sitting at my (...) (17 years ago, 29-Jul-07, to lugnet.robotics.nxt)

Hi all, (...) Recently, we finished a runtime for the RCX, and discovered the awful state of uploading tools for that platform. In particular, there are at least three versions of firmdl running around the net, each capable handling different (...) (17 years ago, 28-Jul-07, to lugnet.robotics.nxt.nxthacking)

Hi Christian, (...) if you have an endianness problem it should be visible. The easiest would be to compare it with a little-endian machine. (...) It uses the SAM-BA protocol, which is rather simple and without error checking, more like what a human (...) (17 years ago, 28-Jul-07, to lugnet.robotics.nxt.nxthacking)

(...) Elizabeth, Could you upgrade to b31 of NXC and see if you still have this problem? You will need to update your TextOut call to put the "false" as the last parameter or leave it out altogether. TextOut(0, LCD_LINE2, "DONE ROTATE"); Also, could (...) (17 years ago, 27-Jul-07, to lugnet.robotics.nxt)

Everyone, Being fair in the judgement in using a global watchdog flag to terminate a task. Honestly, when I have a multi-threaded process, I have always used a watchdog type of flag, mutex, semaphore, etc. to signal a thread to terminate. I hardly (...)
