高手们，帮忙看看， 哪里写错？

开发环境搭建 见：http://www.openedv.com/forum.php?mod=viewthread&tid=27100
TM1637的arduino库：https://github.com/avishorp/TM1637

代码：
#include <Arduino.h>

#include "RTClock.h"
//showNumberDec(int num, bool leading_zero, uint8_t length, uint8_t pos)
//display.showNumberDec(8,true);   Show decimal numbers with/without leading zeros
//display.showNumberDec(0153, True, 4, 0); showNumberDec(int num, bool leading_zero, uint8_t length, uint8_t pos)
#define BOARD_LED_PIN PC13  // Module connection pins (Digital Pins)
#define CLK PB6
#define DIO PB7
TM1637Display display(CLK, DIO);
