使用华大单片机碰到一些问题，不知道有人能帮我解决吗？voidtime0_Init(void){uint16_tu16ArrValue;uint16_tu16CntValue;stc_bt_mode0_cfg_tstcBtBaseCfg;DDL_ZERO_STRUCT(stcBtBaseCfg);Sysctrl_SetPeripheralGate(SysctrlPeripheralBaseTim,TRUE);stcBtBaseCfg.enWorkMode=BtWorkMode0;stcBtBaseCfg.enCT=BtTimer;stcBtBaseCfg.enPRS=BtPCLKDiv16;stcBtBaseCfg.enCntMode=Bt16bitArrMode;stcBtBaseCfg.bEnTog=FALSE;stcBtBaseCfg.bEnGate=FALSE;stcBtBaseCfg.enGateP=BtGatePositive;Bt_Mode0_Init(TIM0,&stcBtBaseCfg);u16ArrValue=0x10000-1600;Bt_M0_ARRSet(TIM0,u16ArrValue);u16CntValue=0x10000-1600;Bt_M0_Cnt16Set(TIM0,u16CntValue);Bt_ClearIntFlag(TIM0,BtUevIrq);Bt_Mode0_EnableIrq(TIM0);EnableNvic(TIM0_IRQn,IrqLevel3,TRUE);}我开启定时中断，为什么不进入中断，而且我发现整个中断函数都不运行，不知道怎么回事，有人知道吗？还有就是我使用模拟IIC，来读取DS1307，读到的数据全是0voidDS1302_Init(void){stc_gpio_cfg_tstcGpioCfg;Sysctrl_SetPeripheralGate(SysctrlPeripheralGpio,TRUE);stcGpioCfg.enDir=GpioDirOut;stcGpioCfg.enDrv=GpioDrvH;stcGpioCfg.enPu=GpioPuEnable;stcGpioCfg.enPd=GpioPdDisable;stcGpioCfg.enOD=GpioOdDisable;stcGpioCfg.enCtrlMode=GpioAHB;stcGpioCfg.bOutputVal=TRUE;Gpio_Init(GpioPortB,GpioPin3,&stcGpioCfg);Gpio_Init(GpioPortB,GpioPin4,&stcGpioCfg);if(Read_DS1302(0x08)!=0xF0){Write_DS1302(write_address[0],0x30);//ÃëWrite_DS1302(write_address[1],0x09);//·ÖWrite_DS1302(write_address[2],0x15);//ʱWrite_DS1302(write_address[3],0x29);//ÈÕWrite_DS1302(write_address[4],0x09);//ÔÂWrite_DS1302(write_address[5],0x03);//ÖÜWrite_DS1302(write_address[6],0x21);//ÄêWrite_DS1302(0x08,0xF0);}}这是什么原因
