JavaLaurence Geschrieben April 24, 2014 at 17:04 Share Geschrieben April 24, 2014 at 17:04 Hi, Quick the Easter discount clock is ticking. I would like to try and detect and measure cars driving past in our street by using two Sound Intensity Bricklets to get some kind of "stereo" waveform each time a car passes. Analysing those waveforms should allow me to deduce speed. To get this to work, I'll need a reasonable sampling rate. So Q: What's the fastest sampling rate for this Bricklet? Actually, wouldn't it be nice if each bricklet had an API that can tell a program what its maximum sampling rate can be ? Thx.

remotecontrol Geschrieben April 25, 2014 at 11:48 Share Geschrieben April 25, 2014 at 11:48 Hi JavaLaurence, all bricklets can trigger max 1000 callbacks per second if connected via USB, so you might never get more than 1000 different values per second (I would expect that this is a little less). If you use WIFI, this is something about 80-110 callbacks per second max. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
