(1)外部定义中断服务子程序 @far @interrupt void EXTI3 (void) { disableInterrupts(); counter (); enableInterrupts(); } (2)声明外部中断子程序 extern void EXTI3 (); (3)配置外部中断子程序向量表 struct interrupt_vector const _vectab[] = { {0x82, (interrupt_handler_t)_stext}, {0x82, No...
1. 配置系统中断的打开或关闭 2. 配置想要使用的中断向量的软件优先级 3. 打开相应的外设中断源的中断,就可以响应了 针对于外部中断来说,首先,STM8的每一个引脚都能支持外部中断,但是在中断向量上,不是每一个引脚都有 独立的中断向量,而是每个端口共用一个中断向量,在端口中断向量处理函数中检查到底是哪一个引...

INTERRUPT_HANDLER(TIM2_UPD_OVF_TRG_BRK_IRQHandler, 19); 这个函数是定时器TIM2 向上计数中断服务函数,TIM2定时中断服务代码就在这里添加。 其中TIM2_ClearITPendingBit(TIM2_IT_Update); 表示清除中断服务标志。 定时器实验测试: 1.我们先打开Lora模块的原理图如下: ...
中断的入口INTERRUPT_HANDLER(TIM4_UPD_OVF_IRQHandler, 23),位于stm8s_it.c文件下面,由系统决定,我们不用去修改。 每次进入中断,需要添加语句TIM4_ClearITPendingBit(TIM4_IT_UPDATE);清除中断标志位。后面的由我们自己添加,我这里为了方便测试,使用gTIMTiming_Num变量,这样可以使定时时间为1ms的倍数。
