Re: A vario now working!

Greg, I have managed to get a file compiled, uploaded and the openXsensor vario working! Using BMP180 baro. My only remaining dilemma is trying to figure out what I was doing wrong before!.................... Question: How do I save this compiled file reliably for later use? I might get a couple mo...

Re: RPM resolution?

That's good Greg. Just to clarify; by how much does the reading increase when the aircraft is in the air after this mod? That is, when the engine is unloaded to some degree? Hi Jim, I haven't yet had the opportunity to test it in the air - just backyard trial to make sure the combo of resistor and ...

Re: RPM resolution?

First, a RC filter does not cut off 100% of the frequencies higher than a value. It is a progressive filter. More important: the formula applies on a sinusoîdal signal but the signal coming from the Hall sensor is not sinusoïdal. It is a digital signal and probably look more as a pluse. So it conta...

Re: RPM resolution?

Some feedback on the subject I raised: I added a simple low pass filter to the signal line coming directly from the Hal pickup which splits via a y-lead before feeding the CDI. Without the filter the rpm values were erratic and over-reading in flight. Knowing nothing about the subject I ended up wit...

Re: RPM resolution?

For RPM, oXs counts the number of pulses in an enlapsed time. If the signal coming on pin D8 is noisy, the arduino can recognise some "noise" as a pulse and so report a to high RPM value. In order to avoid (reduce) this, you can try adding a RC filter between the CDI and the pin D8. Resistor is put...

Re: RPM resolution?

In the air the airplane is moving, I believe it is normal for the RPM to increase. Example. Try making a dive. The RPM will increase. João Hi João, Absolutely but when the telemetry is reporting 9500 rpm for a 30cc gas engine and you're in straight and level flight and not even at full throttle - s...

Inconsistent RPM values

Guys, I'm wondering if anyone has experienced this phenomenon and has a solution..

Re: New to openXsensor - GPS and smartport question

I'll give it a go...

Is it necessary to drop the voltage from D6 to the Rx pin on the GPS to 3.3v? I'm sure I read somewhere that it can handle 5v but can't find where I saw that mentioned.

And I presume once data starts to flow that the D2/4 pin should start showing more than 0.3v?

Re: New to openXsensor - GPS and smartport question

Admittedly I'm testing it indoors and comparing with the FrSky GPS which gets discovered irrespective of whether it has a fix or not.

I'll have to wait for the rain in Sydney to stop before I can take the test bench outside. 😂😉

Hi guys, can't seem to find any previously answered question of how to get the small red joystick on the bottom left of the radio simulator to work in Companion 2.3 - any ideas?
This would simulate input for JXs and JYs

I'll give this a go. For some reason i can't seem to be able to get simple alarms like the radio inactive alarm to work - must have changed a setting somewhere inadvertently.

Any chance that amending models in Eepesky on a mac could be bringing in an issue?
