GD32定时器触发HardFault_Handler
想用GD32F330开发板的定时器1做个定时的角度反馈，设了个10K频率的定时器中断，每计数10次反馈一次角度，结果发现了加了if语句来判断后，一直触发HardFault_Handler，无法执行if里面打印角度操作；关了if语句，又没问题了，操作正常执行。然后我一步步注释代码，发现在判断语句前，用串口打印一次在进行判断，判断语句也不会触发HardFault_Handler，里面指令也是正常进行。想请教一下大伙儿，这是个什么问题？是我定时器配置错了嘛？这是我的定时器配置：voidtimer1_interrupt(void){rcu_periph_clock_enable(RCU_TIMER1);timer_parameter_structtimer_initpara;timer_deinit(TIMER1);timer_initpara.prescaler=35;timer_initpara.alignedmode=TIMER_COUNTER_EDGE;timer_initpara.counterdirection=TIMER_COUNTER_UP;timer_initpara.period=199;timer_initpara.clockdivision=TIMER_CKDIV_DIV1;timer_initpara.repetitioncounter=0;timer_init(TIMER1,&timer_initpara);timer_interrupt_enable(TIMER1,TIMER_INT_UP);timer_enable(TIMER1);}voidnvic_config(void){nvic_irq_enable(TIMER1_IRQn,1,1);}inti=0;uint16_tangle;voidTIMER1_IRQHandler(void){if(timer_interrupt_flag_get(TIMER1,TIMER_INT_UP)!=RESET){i=i+1;timer_interrupt_flag_clear(TIMER1,TIMER_INT_UP);if(time==10){angle=ssi_ReadAngle();printf("%d\r\n",angle);i=0;}}}
