[ALIBABA-125]

Witam.
Szukam osoby chętnej która dopisze mi do programu sterowanie i ustawienie przyciskami godzin minut i sekund.
Zegar zrobiony na bazie arduino nano, DS3231, MAX1719 i sześciu wyświetlaczy 7 segmentowych.
Poniżej kod programu

Kod:

#include <DS3231.h>         

// define pins attached to MAX7219 (and also see notes above)
#define MAX7219_DIN          12
#define MAX7219_CS            10
#define MAX7219_CLK          11

// enumerate the MAX7219 registers
// See MAX7219 Datasheet, Table 2, page 7
enum {  MAX7219_REG_DECODE    = 0x09,
        MAX7219_REG_INTENSITY = 0x0A,
        MAX7219_REG_SCANLIMIT = 0x0B,
        MAX7219_REG_SHUTDOWN  = 0x0C,
        MAX7219_REG_DISPTEST  = 0x0F
    };

// enumerate the SHUTDOWN modes
// See MAX7219 Datasheet, Table 3, page 7
enum  { OFF = 0,
        ON  = 1
      };



// create an instance of the DS3231 called 'rtc',
// and specify the hardware interface PINS
DS3231 rtc(SDA, SCL);


const static byte charTable [] PROGMEM  =

  // ... display Time, hh-mm-ss
  for ( int i = 0; i < 6; i++ )
  {
    // read the time as a string from the RTC
    str = rtc.getTimeStr(FORMAT_LONG);
    Serial.println(str);        // debug
    displayTime(str);          // display on the 7-segment
    delay(1000);
  }
}

// ... write a value into a max7219 register
// See MAX7219 Datasheet, Table 1, page 6
void set_register(byte reg, byte value)
