Re: Gspd: 3D speed with GPS and altimeter

Your log looks strange. Eventually there is an issue with antenna placement/bad reception. You can verify GPS signal quality with some changes in the code, to be able to see and log number of sats and PDOP.

Re: High(er) resolution current sensor

Yes, of course, this is the standard approach. The workaround with ADS1115 is cheaper and more precise. It does not need any code change in openXsensor. Mstrens prepared this solution already in his code, i only wanted to show a complete, slimsize build and configuration.

High(er) resolution current sensor

The Lantian-100A-ACDC-Linear-Current-Sensor-Hall-Current-Sensor-Module is cheap (about 6$) and precise. It's size can be reduced to Arduino pro mini size. Still there is the disadvantage with it's 2.5V offset. The voltage output is 2.5 to 4.5V. The 10bit Arduino resolution gives only about 0.2A curr...

Re: OpenXSensor 2 batteries with 2 cells voltage problem

As proposed two sensors with different sensor ID is the way to go. If you want to stay with one sensor, you can make a workaround with an ADS1115 using it's two differential inputs for the second battery transmitting the cell voltages in A3 and A4 field for example. A calculated sensor can be used f...

Re: GPS & Arduino Pro mini

Our German forum has a very active oXs community and therefore a good overview about troubleshoting oXs. Mstrens GPS routines are working perfect, not a single glitch. If there were issues, they were hardware or user related. Is Arduino indeed connected to SPort on antenna side? Some, including me, ...

Re: GPS & Arduino Pro mini

Did you verify, that power is indeed connected to Arduino VCC? Some Arduinos have a huge regulator dropout. Feeding them through VIN/RAW with 5V results in a low VCC voltage.

Re: GPS & Arduino Pro mini

Everything seems to be OK. Eventually you did not give enough time to establish a sufficient sat fix for oXs. To be sure, place the GPS outside for 10min with free view to the sky and then start sensor discovery. If this fails also, try with another GPS unit.

Re: Airspeed sensing with TEK probe and diff pressure sensor planned?

From my point of view the openXsensor approach is much cleaner. No TEK-probe needed, airspeed is measured with a pitottube. TEK vario vspeed gets calculated, users can switch between compensated and standard vario and energy compensation is adjustable from TX.

Re: Pairing RC receiver with FrSky X9E OpenTx 2.2.1

Seems you have different D16 protocols in TX and RX, D8 works, because there is only one. If devices are from Europe, there is a good chance to have LBT firmware installed. To be sure, update your TX (internal XJT) to 170317 FCC (=NoEU).

Re: ACS758LCB Current sensor

Some ACS are labeled wrong and are indeed bidirectional. You can try to change MVOLT_AT_ZERO_AMP to 2500 and test again - or measure analog out first with a DVM. Eventually your Horus (FrTX?) has an issue with negative numbers (simply guessed)

Did you read chapter 6 in oXs_config_description.h ? You may connect your ACS to every analog in A0 ... A7, but A4 and A5 are eventually already used by GY63. Which one do you use? Which power supply for Arduino do you use and where is it connected? RAW or VCC? Please post your 2 config files here. ...
