I didn't really encounter much problems streaming data from it. You can slim down the serial protocol the Arduino sends out quite a bit and speed up the baudrate too. It can be pretty fast that way. > For a quick, darn cheap and easy (and high resolution: 10bit) little > device i ve built a couple of these: > http://1010.co.uk/avrhid.html > these ones send HID protocol to USB, very fast and 10bit resolution, 8 > analog ins and 6 digital ins. HID adds to the protocol transmitted. Resolution is the same as the Arduino can be (10bit). Same amount of I/O ports. The Create USB Interface can be built for about 15 euro in parts (without a custom made PCB), also does USB HID, and gives you 13 analog in at 10 bit, and a whole lot more digitial I/O. It's based on the PIC, and you can choose to program in C or ASM. I'm not sure the open source PIC tools are yet up to the chip used though. That might be a drawback. If you want an overview of what's out on the market... take a look at http://www.sensorwiki.org especially http://www.sensorwiki.org/index.php/Sensor_interfaces sincerely, Marije _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
