Ds3231 + установка часов и минут кнопками

Всем привет. МОжет есть у кого-нибудь кусок кода для arduino - установка часов и минут кнопками на RTC 3231. Спасибо

 

Код (C++):

#include <Wire.h>

struct _I2CRealRimeClockTime
{
byte seconds = 0;
byte minutes = 0;
byte Hours = 0;
byte weekday = 0;
byte day = 0;
byte month = 0;
byte year = 0;
unsigned long startTime = 0;
};
_I2CRealRimeClockTime _RTC1;
bool _RTCST_Ost1 = 0;

void setup()
{

Wire.begin();
delay(10);
Wire.beginTransmission(68);
Wire.write(0x0E);
Wire.write(B00000000);
Wire.write(B10001000);
Wire.endTransmission();
_RTC1.startTime = millis() - 1000;

}
void loop()
{
if (0)
{ if (!(_RTCST_Ost1))
{set3231Date(0x68, &_RTC1, -1, (0), (0), -1, -1, -1, -1);
get3231Date(0x68, &_RTC1);
_RTCST_Ost1 = 1;
}}
else
{ _RTCST_Ost1 = 0;}
}

bool _isTimer(unsigned long startTime, unsigned long period )
  {
  unsigned long currentTime;
currentTime = millis();
if (currentTime>= startTime) {return (currentTime>=(startTime + period));} else {return (currentTime >=(4294967295-startTime+period));}
  }
byte decToBcd(byte val)
{
   return ( (val/10*16) + (val%10) );
}
void set3231Date(int addres, struct _I2CRealRimeClockTime *timeStruct, int sec, int  minut, int hou, int dat, int mo, int ye, int daW)
{
  byte temp;

  Wire.beginTransmission(addres);
  Wire.write(0x00);
  if (sec < 0) {
    temp = timeStruct -> seconds;
  } else {

  }
  Wire.write(decToBcd(temp));

  } else {

    temp = timeStruct -> month;
  } else {
    temp = mo;
  }
  Wire.write(decToBcd(temp));
  if (ye < 0) {
    temp = timeStruct -> year;
  } else {
    temp = ye;
  }
  Wire.write(decToBcd(temp));
  Wire.endTransmission();
  timeStruct ->startTime = millis() - 1000;
}
void get3231Date(int addres, struct _I2CRealRimeClockTime *timeStruct)
{
  if (!(_isTimer ((timeStruct ->startTime), 250))) {
    return;
  }
  Wire.beginTransmission( addres);
  Wire.write(0x00);
  Wire.endTransmission();
  Wire.requestFrom(addres, 7);
  if (Wire.available()) {
    byte  seconds = Wire.read();
    byte minutes = Wire.read();
    byte hours   = Wire.read();
    byte day     = Wire.read();
    byte date    = Wire.read();
    byte month   = Wire.read();
    byte year    = Wire.read();
    timeStruct -> seconds = (((seconds & B11110000) >> 4) * 10 + (seconds & B00001111));
    timeStruct -> minutes = (((minutes & B11110000) >> 4) * 10 + (minutes & B00001111));
    timeStruct -> Hours = (((hours & B00110000) >> 4) * 10 + (hours & B00001111));
    timeStruct -> weekday = (day & B00000111);
    timeStruct -> day    = (((date & B00110000) >> 4) * 10 + (date & B00001111));
    timeStruct -> month   = (((month & B00010000) >> 4) * 10 + (month & B00001111));
    timeStruct -> year    = (((year & B11110000) >> 4) * 10 + (year & B00001111));
  } timeStruct ->startTime = millis();
}

Боюсь спросить, а в каком месте там управление кнопками?
