Часы на семи-сегментных индикаторах

Есть модуль часов DS3231 подключенный к Ардуино Уно по I2C, задача вывести время и дату на 6 разрядов семи-сегментных индикаторах подключенные по SPI подключенных через каскад сдвиговых регистров 74HC595. На фото скетч только под индикаторы.
#include "Wire.h"
#include <DS3231.h>
#define DS3231_I2C_ADDRESS 0x68
// Convert normal decimal numbers to binary coded decimal
byte decToBcd(byte val)
{
return( (val/10*16) + (val%10) );
}
// Convert binary coded decimal to normal decimal numbers
byte bcdToDec(byte val)
{
return( (val/16*10) + (val%16) );
}
const byte latchPin=6;//st
const byte clockPin=7;//sh
const byte dataPin=5;//ds
// binary code for shift register & 7segment indicator
byte number[] = {0b10001000,0b10111011, 0b00011100, 0b00011001, 0b00101011, 0b01001001, 0b01001000, 0b10011011, 0b00001000, 0b00001001};
void setup() {
pinMode(latchPin, OUTPUT);
pinMode(clockPin, OUTPUT);
pinMode(dataPin, OUTPUT);
Wire.begin();
Serial.begin(9600);
}
void loop()
{
{
Wire.requestFrom(DS3231_I2C_ADDRESS, 7);
{
*second = bcdToDec(Wire.read());
*minute = bcdToDec(Wire.read());
*hour = bcdToDec(Wire.read());
byte second, minute, hour;
read DS3231 time(&second, &minute, &hour);
}
//Присваеваем значение для переменных
int h1 = hour / 10;
int h2 = hour % 10;
int m1 = minute() / 10;
int m2 = minute() % 10;
int s1 = second() / 10;
int s2 = second() % 10;
}
digitalWrite(latchPin,LOW);
shiftOut(dataPin, clockPin, LSBFIRST, number[s2]);
shiftOut(dataPin, clockPin, LSBFIRST, number[s1]);
shiftOut(dataPin, clockPin, LSBFIRST, number[m2]);
shiftOut(dataPin, clockPin, LSBFIRST, number[m1]);
shiftOut(dataPin, clockPin, LSBFIRST, number[h2]);
shiftOut(dataPin, clockPin, LSBFIRST, number[h1]);
digitalWrite(latchPin,HIGH);
delay(500);
}
Вылезает куча ошибок
