(...) The memory used by a program while it is running is not the same memory used for storing the program (flash). There isn't any way that I know of at this point to find out how much memory a program uses while it is running or how much of (...) (20 years ago, 6-May-06, to lugnet.robotics)

| | Re: NXT Sound Sensor

(...) There is a curious 6th wire connection from the sound sensor which sends analog sound to the CPU. I am assuming that using some 3rd party firmware, it might be possible to digitize and process sound data. But I think turning the CPU into a DSP (...) (20 years ago, 6-May-06, to lugnet.robotics)

(...) This is the on-screen programming system. It's pretty rudimentary, but it lets you build very simple programs with only your NXT (no computer needed). Slots 1 & 3 let you 'do' something, slots 2 & 4 essentially control how long that action (...) (20 years ago, 5-May-06, to lugnet.robotics)

(...) The raw mode still just returns one number - essentially the integrated sound energy, where the weighting function is determined by the sensor mode (dB or dBA) and is all done on-board the sound sensor itself, not in the NXT. (...) You only (...) (20 years ago, 5-May-06, to lugnet.robotics)

(...) Hmmm is there a "raw data" mode for the sound sensor? Seems to me, it may be possible (maybe not yet but one day) to write a program that does FFT analysis, as long as it can get the raw wave data from the sensor. I'm assuming the "tone mode" (...) (20 years ago, 5-May-06, to lugnet.robotics)
