Electronic – AVR Stick Data Logger Usage


Has anyone used this data logger (or similar) with v-usb to collect data?


If so, what is the maximum times per second voltage data can be sent at HID messages? (I can't understand the spec sheets)
And can it work with an ultrasonic rangefinder (or similar) also from sparkfun?


Best Answer

The default firmware sends samples to the host once per second. If you need a faster sample rate, you'll need to write custom firmware (and probably some custom USB HID drivers). The MaxSonar rangefinders, available from spaarkfun or littlebird electronics, have an analog output that's perfect for the AVR stick.
