Frage an die Experten:
Ich habe einen OpenXSensor zusammengestellt, der mir Vario,GPS und den Strom anzeigen soll. Dazu über ein Y-Kabel den FrSky Drehzahlsensor mit 2 Temp.Fühler angeschlossen.
Alles klappt prima bis auf die Stromanzeige. Bei der Sensorsuche wird zwar CURR als Sensor gefunden, aber kein Wert angezeigt (auch nicht bei laufenden Motor und leichtes abbremsen von Hand ).
Verbaut hatte ich zunächst einen ACS 785 100A bidirektional mit einer Einstellung
in der oXs_config.h :
// ***** 6.3 - Max number of Lipo cells to measure (and transmit to Tx) *****
#define NUMBEROFCELLS 6 // Put this line as comment or set value to 0 (zero) if you do not want to transmit cell voltages.
// ***** 6.4 - Current parameters *****
#define PIN_CURRENTSENSOR 8
#define MVOLT_AT_ZERO_AMP 2500 // in millivolt
#define MVOLT_PER_AMP 20 // in milliVolt per Amp
//#define RESISTOR_TO_GROUND_FOR_CURRENT 19.8 // put as comment or set to 0 if no divider is used
//#define RESISTOR_TO_CURRENT_SENSOR 39 // put as comment or set to 0 if no divider is used
Den ACS 785 ausgebaut und auf evtl. loses Kabel usw. untersucht, ohne Ergebnis. Meine Vermutung ,das Teil hat einen Schaden.
Dann einen ACS 712 30A eingebaut ,MVOLT_PER_AMP auf 66 eingestellt .
Ohne Erfolg .
Auf der Taranis hätte ich auch gerne folgende Werte noch angezeigt bekommen:
momentaner Strom A, verbrauchte Energie mAh und momentane Akkuspannung V.
Unten meine oXs_config.h . Wo habe ich etwas falsch eingestellt ?
Es wäre schön, wenn mal einer der Experten einen Blick darauf wirft.
Danke
