Der Code ist von der Herstellerseite mit dem Dateinamen (EBK7000_PGA_TW2)
Aus meinem Wissensstand kann das doch nicht der Code sein um daten zu messen, oder ? Da das Programm ja im loop teil mit eine switch anweisung beginnt auch wenn ich den virtuellen monitor aufhabe und z.B. einen Buchstaben drücke passiert nichts...
Würde euch der Code etwas sagen, also wüsstet ihr was er Grob macht, und woher wiess ich welche sensor jetzt angeschlossen ist und welcher angesprochen ist ?
Zu dem Kit habe ich 4 Sensoren die ich an das shield anschließen kann ein Hauptsensor und den Referenzsensor.
Weiss man aus dem Code welcher Sensor angesprochen ist und wie sie zusammenarbeiten oder arbeiten sie überhaupt zusammen ?Habe nochmal neu angehängt danke für die schnellen antworten Tommy

nur sein Projekt angenommen was in meinem Plan im 4. Semster Maschbau dazugehört
