Hello, i have Elev-8 with HoverflySport controller, when i see in manual page this board support Maxbotic Sonar for altitude hold. my question, is it possible to replace maxbotic sonar with Ping))) Ultrasonic from parallax?

    I'm pretty sure the Ping wont work with the Hoverfly Sport without a change to the Hoverfly's firmware. I believe (IIRC) the Maxbotic sensor outputs a continuous (PWM is used by the Hoverfly) signal while the Ping needs a trigger pulse to active it.

    Besides working with the Elev-8, the Maxbotic sensor also works with the Scribbler 2 robot (the Ping doesn't).

    BTW, SparkFun sells the Maxbotic sensor.

    I already have Elev-8 and Ping))) from parallax, but if not compatible i will try ultrasonic sensor from maxbotic.

    I just reviewed the Maxbotic LV-EZ0 datasheet. It takes a reading every 49ms and does not require a trigger pulse to activate it. A Ping sensor would not behave the same as the Maxbotic sensor.
