Re: New beta version of openXsensor (=openXvario)

I have prepared a new version where you can measure up to 6 NTC (with the same characteristics). When there is only one or two, you can get the temperature(s). When there are more than 2, you get the lowest and highest temperature and the index of the highest. I will put it soon on github That's gr...

Re: New beta version of openXsensor (=openXvario)

One option to keep config simple and to reduce the number of data being sent could be to calculate and transmit only one temperature (the max) of several NTC and to consider that each NTC have the same coefficient. Is this good enough? For anything more than 2 cylinders, that would be fine. If the ...

Re: New beta version of openXsensor (=openXvario)

I will look at the easiest way to implement several NTC in future version. Config would be easier if all NTC have the same characteristics. Is this acceptable? Thanks mstrens! One would likely be just fine. If it's possible to add 2, I think that's the max that would ever be needed. The most common...

Re: New beta version of openXsensor (=openXvario)

Indeed, in current code, only one NTC is supported. Do you need more than one. If so how much? Would be good to have at least 2 (Same as the Frsky RPM sensor), 5 would be awesome for a friend who is running a 5-cylinder radial. I assume the intention is to make them available as config options (ie....

Re: New beta version of openXsensor (=openXvario)

Looks like it's locked to a single sensor. Any chance of extending this to additional sensors, or am I missing something? [/quote] It is not clear for me what you mean by "locked to a single sensor". [/quote] Hi mstrens! My apologies. I should have clarified. The new NTC code seems to be ...

Re: New beta version of openXsensor (=openXvario)

Here a version of oXs that should calculate the temperature using a NTC. I did not (yet) put the new parameters and the description in the 2 oXs_config files but you can find some description starting at line 980 in the .ino file. If this is not clear of if you do not get the expected result, just ...
