STM8SI/O口中断有问题！

STM8SI/O口中断有问题！ [复制链接]

定义：GPIO_Init(PORT_D, GPIO_PIN_7, GPIO_MODE_IN_PU_IT);
EXTI_SetExtIntSensitivity(EXTI_PORT_GPIOD, EXTI_SENSITIVITY_FALL_ONLY);

@near @interrupt void EXTI_PORTD_IRQHandler (void)中始终产生不了中断？
难道资料有误还是芯片有问题？

                                 用过STM8S105的中断，没问题。看一下反汇编及初始化完的寄存器

                                 中断向量地址填写了没？

这个还有问题吗？

                                 怎么没人回复？

                                 解决了，问题的PD7是没有中断的，只有TIME1的中断

                                 PD7是TLI中断
