The shiftin and shiftout is not implemented yet. You can use a for loop do it.

@sh4had you may add this function in your sketch to use the shiftout function.

void shiftOut(uint8_t dataPin, uint8_t clockPin, uint8_t bitOrder, uint8_t val)
{
 uint8_t i;
 for (i = 0; i < 8; i++) {
 if (bitOrder == LSBFIRST)
 digitalWrite(dataPin, !!(val & (1 << i)));
 else
 digitalWrite(dataPin, !!(val & (1 << (7 - i))));
 digitalWrite(clockPin, HIGH);
 digitalWrite(clockPin, LOW);
 }
}
