求单片机51系列的计数器C语言程序,要求24进制,可进位

#include <reg51.h >

#include <intrins.h >sbit key = P2^0

const unsigned char LED7Code[]={

0xC0, // 0

0xF9, // 1

0xA4, // 2

0xB0, // 3

0x99, // 4

0x92, // 5

0x82, // 6

0xF8, // 7

0x80, //数祥 8

0x90, // 9

0x88, // A

0x83, // B

0xC6, // C

0xA1, // D

0x86, // E

0x8E // F

}

unsigned char count = 0

/*********************************************************/
