Re: openXsensor - Jeti -NTC

Hi, I found a stupid mistake. I wrote calculate_rpm "si" instead of "yes".... free translation... :-)

It seems now to work. I still have to test it with running engine.

Ciao Stefano

Re: openXsensor - Jeti -NTC

It is connected to Gnd and Pin 8. Revolution does not appear. I have only temperature, also after a reset.

Re: openXsensor - Jeti -NTC

Hi, I have performed several tests. 1) old software (NUMBEROFCELLS=1): - T=-32.76 - Cell1=Cmin=CellAll=58.88 2) new software (NUMBEROFCELLS=1) - T=16deg (correct!!!) - Cell1=Cmin=CellAll=59.8 3) new software (NUMBEROFCELLS=0) - T=16deg (correct!!!) I have heated the NTC and the temperature rise (the...

Re: openXsensor - Jeti -NTC

Thank you for the help. In my setup I am using an arduino pro mini (3.3V), a 100kOhm Thermistor and a reference resistance (to vcc) of 9.9 kOhm. The coefficients of the thermistor were calculated with the aid of a calibration performed in hot water (20 - 95 Degrees) (temperature in Kelvin, resistanc...

openXsensor - Jeti -NTC

Hi, I am trying to setup openXsensor with NTC for Jeti. I have tried different configurations of the config file, without success. The measured voltage seems to be correct and the Steinhart parameters have been computed with a calibration. Could be a problem with the Jeti transmission protocol? Has ...

Re: Fas100 - wrong current measurement

Thank you for info. I will check mine, but how can I find if it is a 40a instead of a 100a?

Re: Fas100 - wrong current measurement

I made further investigations. I have tryied with a FAS-40 and the reading on the 9x display is correct. The problem is related to the FAS-100. I assume is my new fas-100 that is not working correctly.

Fas100 - wrong current measurement

Hi I have a problem with the fas100 (frsky with telemetry mod). I have connected it to the hub2.0 that route to the receiver data port. After installing the last open9x firmware the measured current shows about 40A instead of about 0A. The analog output have a value of 0.6v corresponding to 0A. I am...
