I ran a latency test today using arduino & max msp , I used a maxuino patch to communicate between the two.
what i wanted to find out was : How long does it take to send a signal from the PC computer out to arduino and back into the computer? I sent a signal along the following path : max/msp > serial/usb > arduino digital out >arduino digital in> usb/serial>max msp.
i used a timer module inside max msp to take the readings.
Each time i send a test signal/bang out of max/msp I get a range of latencies for its return back in.
it is not a constant figure, i have readings between 3 ms > 19ms each time i send a single bang.
just thought id post this. maybe there is a way to tighten this up ?
peace : )
