 | | HELP! NXT brick flash now read-only!!
|
|
All, Up until this point, I kept hearing that it was pretty much next to impossible to "brick" a brick. However, I think I've managed to be the first person to prove that it *can* be done (not that I'm proud of this fact :-( ). A few weeks back, I (...)

I don't know how the NXT-G thread/task scheduler works. Just wondering if anyone has any idea on the impact on execution performance when multiple threads are running? And how often threads are scheduled? For example, if you have a "main" thread (...) (18 years ago, 31-Jan-07, to lugnet.robotics.nxt)

In practicality, it is not a good practice to kill another thread without some sort of synchronization anyway. However, if one thread is not responding for a long period of time, it will be good to allow the parent thread to terminate it. (...) (18 years ago, 29-Jan-07, to lugnet.robotics.nxt)
