RPM measuring with gasser heli

Posted by Armin Beyel on June 19, 2015 at 8:38am

@ Rob,

I read one discussion of you, about rpm measuring. You should have some code to add to the ardupilot. I am using vers. 3.2.1 of arducopter (latest for APM 2.6 right)) and would like to add some code for rpm measuring of the rotor with a hall sensor. The rpm, I want to transmitt to my frsky receiver and read on my taranis. In the moment I see the throttle signal, which means the stick position 0....100 %.

I want to change this value with the real rpm of the rotor, is that possible?

If your code is working for this, may I have a copy of it?

@all

Anyway please give me suggestions how to display real rotor rpm via frsky telemetrie to taranis.

I have already installed a arduino pro mini and a hall sensor, but i also want to see the gps status and so on from the apm.

Best regards

Armin

      Hi Rob,

      i have a communication between APM -> Arduino pro mini -> and frsky d-receiver generally working.

      The origin of the code is from here: http://vizual54.github.io/APM-Mavlink-to-FrSky/

      I have a code for measuring average rpm, see attached file.

      My problem is to combine both programms, so that i get the real rpm as rpm through frsky telemetrie.

      My arduino programming knowledge is too small to do that, i am trying this since 2 months now. I added the "rpm ave" code in the main programm, but i am not able to change the "EngineSpeed()" with my "rpm ave".

      I use a "A3144" hall sensor with a pullup resistor.
