Hallo Leute,
da ich mich zur Zeit an einem Projekt befinde, habe ich eine Frage bezüglich meines Sketches. Dieser liefert mir Analogwerte für Licht(0-1023). Diese Werte loggt der vorgefertigte Sketch auch samt Uhrzeit, im Prinzip wie ich es haben möchte. Zusätzlich möchte ich noch die Temperatur mitloggen. Da mein Sketch aber für einen analogen Temperatursensor ausgelegt ist, ich aber einen digitalen Temperatursensor (ds18b20) benutzen möchte, passt der vorgefertigte Sketch des DataloggingShield nicht. Ich habe schon selbst versucht diesen Sketch anzupassen, jedoch bekomme ich immer unterschiedliche Fehlermeldungen. Jetzt die Frage: Würde mir jemand behilflich sein diesen Sketch anzupassen?
Beide Sketches funktionieren unabhängig voneinander zu 100%, jedoch möchte ich wie erwähnt, den "TemperaturSketch", der mir digitale Werte liefert, in den DataloggingSketch einbinden. Ist dies viel Arbeit?
Hier die beiden Sketches:
DataloggingSketch:
#include <SD.h>
#include <Wire.h>
#include "RTClib.h"
// A simple data logger for the Arduino analog pins
// how many milliseconds between grabbing data and logging it. 1000 ms is once a second
#define LOG_INTERVAL 1000 // mills between entries (reduce to take more/faster data)
// how many milliseconds before writing the logged data permanently to disk
// set it to the LOG_INTERVAL to write each time (safest)
// set it to 10*LOG_INTERVAL to write all data every 10 datareads, you could lose up to
// the last 10 reads if power is lost but it uses less power and is much faster!
#define SYNC_INTERVAL 1000 // mills between calls to flush() - to write data to the card
uint32_t syncTime = 0; // time of last sync()

Danke schonmal vielmals.
P.S: Ich bin relativ neu auf diesem Gebiet unterwegs, deshalb entschuldige ich mich schon einmal im vorraus für meine Unwissenheit, hoffe jedoch, dass mir jemand behilflich sein kann.
Danke.
