DCF77_Arduino_without Lib

Projects Programming
1

Hey Ladies and Gentleman,

i have problem. i have to programming DCF77 outputs on a Arduino UNO but without any Libraries. I wrote a small programm to read the Pin 2 where the signal ist connected from the DCF77, but there ist no result or a result that gave me 2 instead to declare the pin 2.

My small Code:

#define signal 2 //DCF77 Signal über PIN 2 connecten

//int signal = 2; //Signal wurde an Pin 2 festgelegt
int eingangsbit = 0; //variable zum zwischenspeichern der Werte

void setup() {

pinMode(signal, INPUT); //Ausgang über signal ansteuern
digitalWrite(signal, HIGH);

Serial.begin(9600);

}

void loop() {

digitalWrite(signal, HIGH);

Serial.println(signal);
}

eingangsbit = is to buffer the values

ok now i have read the binary datas and put them in a buffer, but how can i save them in a array? i have wrote a char array with a large of 60 but, the datas there came in are timless... the bits flow per second 1 and 0.
This projekt is to be show a Time.

  Serial.println(signal);

What is this? Printing a pin number that never changes is pointless.

Not with the code you posted.

From the comments in your small code it looks like your native language is German.

In the German forum I've posted a few DCF77 test sketches recently.

Code for showing pulses and their quality:

Code for decoding time (if pulse quality is sufficient):

If you'd like to discuss about the German DCF77 time code signal in German language, you could join that thread in the German forum.

P.S.: The loop() function code you posted above does nothing else but printing the pin number you declared. Perhaps better try reading the pin and print the result:

void loop() {
  Serial.println(digitalRead(signal));
}
