解决库仑计初始化卡死问题

void write_ds2781_cmd(unsigned char cmd, unsigned char address)
{
    unsigned char pres;
restart:
    pres = reset();
    if(pres) //return fause; // Èç¹ûûÓÐÆ÷¼þ£¬·µ»Ø0
    {
        delay_us(100);
        goto restart;
    }
    write_byte(0xCC); //Ö÷»ú·¢³öSkip Net AddressÃüÁî
    write_byte(cmd); // Ö÷»ú·¢³öxxÃüÁî
    write_byte(address); // Ö÷»ú·¢³öµØÖ·ÃüÁî
    //return ture;
}

改成

void write_ds2781_cmd(unsigned char cmd, unsigned char address)
{
    unsigned char pres;
		unsigned char i;
		
		for(i=0;i<50;i++)
		{
			pres = reset();
			if(pres) //pres=1ʱ£¬Î´¼ì²âµ½Æ÷¼þ¡£
			{
				delay_us(100);
			}
			else break; //pres=0ʱ£¬¼ì²âµ½Æ÷¼þ¡£
		}
		
    write_byte(0xCC); //Ö÷»ú·¢³öSkip Net AddressÃüÁî
    write_byte(cmd); // Ö÷»ú·¢³öxxÃüÁî
    write_byte(address); // Ö÷»ú·¢³öµØÖ·ÃüÁî
    //return ture;
}
