Ufedt, men SPI bussen kan tilsyneladende ikke håndtere både min SD-kortlæser og mit (ældre ENC20J60) Ethernet modul.
Der kommer en konflikt når de skal dele MOSI pin på pin 11, så enten skal jeg undvære SD-kortet eller også Ethernet modulet.
Datalogningen virker ellers 100% og uden Ethernet modulet ser koden således ud:
Kode: Vælg alt
#include <OneWire.h>
#include <DallasTemperature.h>
#include <SD.h>
#include <RTCdue.h>
// Data wire is plugged into port 2 on the Arduino
#define ONE_WIRE_BUS 2
//CS on Pin 4
const int chipSelect = 4;
// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
// Init the DS1307
RTC_DS1307 rtc;
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
// Variables
DateTime OldTime, now; // Time variables
const int buttonPin = 6; // the pin that the pushbutton is attached to
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
void setup(void)
{
// start serial port
Serial.begin(9600);
Serial.println("Initialiserer...");
rtc.begin();
// Reset time variables
DateTime now = rtc.now();
DateTime OldTime = rtc.now();
// make sure that the default chip select pin is set to
// output, even if you don't use it:
pinMode(10, OUTPUT);
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
// Check RTC running
if (! rtc.isrunning()) {
Serial.println("RTC koerer IKKE!");
}
// following line sets the RTC to the date & time this sketch was compiled
rtc.adjust(DateTime(__DATE__, __TIME__));
Serial.println("RTC initialiseret, tid indstillet");
// see if the card is present and can be initialized:
if (!SD.begin(chipSelect)) {
Serial.println("SD-kort ikke initialiseret");
// don't do anything more:
return;
}
Serial.println("SD-kort initialiseret");
// Start up the DS18B20 library
sensors.begin();
Serial.println("Sensorer initialiseret");
delay(1000); // wait 1 second
Serial.println("System startet");
}
//***** Functions *****
boolean TimeSkift (void){ // Checks if minute has changed
DateTime now = rtc.now();
if (OldTime.minute() == now.minute()){ // NO change
return false;
}
else { // Change
OldTime = now;
return true ;
}
}
String SkrivTilLog (DateTime now, int Taeller){ // Writes data to logfile
// open the file.
File dataFile = SD.open("datalog.txt", FILE_WRITE);
// if the file is available, write to it:
if (dataFile) {
dataFile.print(Taeller);
dataFile.print(";");
dataFile.print(sensors.getTempCByIndex(0));
dataFile.print(";");
dataFile.print(sensors.getTempCByIndex(1));
dataFile.print(";");
dataFile.print(now.day());
dataFile.print(':');
dataFile.print(now.month());
dataFile.print(':');
dataFile.print(now.year());
dataFile.print(';');
dataFile.print(now.hour());
dataFile.print(':');
dataFile.print(now.minute());
dataFile.print(':');
dataFile.println(now.second());
dataFile.close();
return("Data skrevet til log");
}
// if the file isn't open, pop up an error:
else {
return("Fejl ved aabning af datalog.txt");
}
}
// ***** Mainprogram *****
void loop(void)
{
// Sets date variables
DateTime now = rtc.now();
// read the pushbutton input pin:
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button
// went from off to on:
buttonPushCounter++;
Serial.println("on");
Serial.print("Antal gange knappen er aktiveret: ");
Serial.println(buttonPushCounter);
}
else {
// if the current state is LOW then the button
// went from on to off:
Serial.println("off");
}
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
// Writes data to log if time changes
if (TimeSkift()){
Serial.println(SkrivTilLog (now, buttonPushCounter)); // crash, MOSI pin er optaget af ethernet!
buttonPushCounter = 0; //Reset pushbutton counter
}
}
Den er lige nu sat op til at holde øje med minuttallet (men det kan hurtigt ændres) og hver gang det skifter skriver den til sd-kortet.
Den laver en linje i en tekstfil, hvor den skriver "Antal gange føler er aktiveret" (blop i gærrør), Temperaturen på de 2 sensorer, samt dato og klokkeslæt - herefter nulstiller den sammentællingen af blop i gærrøret og begynder at tælle igen.
Nu vil jeg prøve med nogle andre dimser, da jeg har flere RTC'er og et selvstændigt EthernetShield skulle jeg nok kunne finde en løsning.
