(...) When downloading a program to the NXT using NBC if there is a file with the same name on the NXT already it is first deleted. Then a new file is created and written using the same filename. I don't know whether that means the firmware will (...) (18 years ago, 10-Sep-06, to lugnet.robotics.nxt)

(...) I don't; John Hansen might. While Flash memory does have a limited number of read/write cycles, it appears that the stated limit is conservative, by a large margin... although some of us have thought about a "test to failure" trial, I've not (...)

Does anyone know how the NXT firmware handles writing program files into flash? If you re-flash a program with the same name, does it first erase the sectors that the old program was located in and then re-flash these sectors with the new program? (...)

(...) Hmm, so speed isn't the issue, the issue is that the 'laser' must hit the detector head on. But luckily that was solved by inserting a thin slice of paper inside the 2x1 red transpararent brick and moving it tone stud in front of the sensor. (...)

Standard Lego firmware samples every 3 msec. BricOS is much faster. I believe it is faster than once per second. RobotC on NXT is programmable to be 0.5 msec scan, 1 msec, 2 msec, ... up to 255 msec. But remember the readings are not persistent. If (...) (18 years ago, 9-Sep-06, to lugnet.robotics.nxt)
