Étape 7: Programme d’Arduino pour horloge binaire
Tout programme sont écrit en environnement arduino et transféré à ATMega328 en utilisant arduino uno. ISP programmation protocole est utilisé pour la programmation. J’ai divisé le programme en deux parties, et chacun peut être utilisé indépendamment. Une horloge binaire et l’autre pour le mode digital de l’horloge.
Programme suivant est uniquement pour le mode binaire de la montre et utilisé le bouton bibliothèque:
#include "Wire.h" #define DS3231_I2C_ADDRESS 0x68 #include <Button.h> //https://github.com/JChristensen/Button #define BUTTON_PIN_1 2 //Connect a tactile button switch (or something similar) #define BUTTON_PIN_2 9 //from Arduino pin 2 to ground. #define PULLUP true //To keep things simple, we use the Arduino's internal pullup resistor. #define INVERT true //Since the pullup resistor will keep the pin high unless the //switch is closed, this is negative logic, i.e. a high state //means the button is NOT pressed. (Assuming a normally open switch.) #define DEBOUNCE_MS 20 //A debounce time of 20 milliseconds usually works well for tactile button switches. #define LONG_PRESS 1000 //We define a "long press" to be 1000 milliseconds. #define msec 1 //for brightness control of LED Button myBtn1(BUTTON_PIN_1, PULLUP, INVERT, DEBOUNCE_MS);
