Re: Creating an RPM and Temp Sensor

Also see that RPM is initially set to a value of 60 for some reason in openxsensor.ino

Re: Creating an RPM and Temp Sensor

Broke down and picked up a Function Generator (been meaning to get one for a while). With Blades equals 1 it reads correctly (though a little high) up to 9999 but returns to 0 once it goes above 10000. So some issue there with large numbers. I'll next see about a method to calibrate the reading. ---...

Re: Creating an RPM and Temp Sensor

Now I remember, in radio/src/telemetry/frsky_d.cpp:

frskyData.hub.rpm *= (uint8_t)60/(g_model.frsky.blades+2);

60 / 1 = 60 (with blades = 1)

I did a quick test changing blades = 2 and sure enough, default value displayed is 30.

Re: Creating an RPM and Temp Sensor

Hi Mike, with tied to ground it simply holds the last value displayed. I tried the "Reset Telemetry" feature but then it goes to 60 right away until the pull down to ground is removed. We may need to have a feature to calibrate the value that is read on pin 8 as simply tapping the pin with...

Re: Blades "1"

Companion is still showing 2 to 4 as min and max blades. Have to see if they tried to use -1 as well since Companion occasionally typecasts blades as an unsigned int. Taranis simulator also lets you select "0" as the minimum blade count, suspect offending code is: opentx / radio / src / gu...

Re: Blades "1"

EDIT: I see how you worked around this, simply set MIN_BLADES -1 (with the +2 everywhere, this gives you 1). Now we just need to increase the blade count to allow for Electric Motor RPM sensors like the Eagletree units (uses Motor Pole count), 20 should be a good high enough number for now. --- Look...

Re: Using Telemetry as a source to mix with.

Yes but you will need to add extra sensor variables to the GetValues function as it's rather basic at the moment. So if you know how to code, have at it :-)

Re: Taranis does not alert if Lipo Voltage Sensor disconnect

Yep. I was more concerned if the balance plug somehow came loose from the voltage sensor as the actual sensor gets powered from the balance plug and not the SmartPort data line which is unfortunate. So if the leads vibrate off etc, the sensor dies and the radio still show the last recorded voltage.....
