Xenna Geschrieben March 9, 2012 at 11:04 Geschrieben March 9, 2012 at 11:04 Agreed, if they had one available with a 6m range, I would have ordered one today. OTOH, something like this http://www.sparkfun.com/products/9495 (5v power, analog out) should be easy to use with an Analog In bricklet, shouldn't it? Zitieren

We have an eye on this sensor already, the problem is that it is quite expensive for us to make a Bricklet for this in big quantaties (you can see the price of the sensor). We kind of stretched our financial means with the newest production. However, we will very likely have a Bricklet for one of the Maxsonar thingies by at least June. Zitieren

borg Geschrieben March 11, 2012 at 20:27 Geschrieben March 11, 2012 at 20:27 For the XL-Maxsonar EZ4 it is really easy. You have to connect 3.3V to V+, GND to GND and the analog in port to pin 3. You can then call GetAnalogValue() on the Analog In Bricklet and to convert to cm just calculate analog_value/1024. The whole interpretation of the signal is done by the EZ4 itself. Thats of course nice, but you pay for that feature (the sensor costs ~50$). Zitieren
