NVIC->ICER[(((uint32_t)(int32_t)IRQn) >> 5UL)] = (uint32_t)(1UL << (((uint32_t)(int32_t)IRQn) & 0x1FUL)); 这个函数仅仅做了寄存器操作 小弟想问一下,英飞凌有没有提供类似于Linux的disable_irq,因为disable_irq“关闭中断并等待中断处理完后返回”,也就是说这样是很安全的 ...
Anyway, I'd like to see the rest of your code, especially the part with the NVIC_EnableIRQ. Here you disable the IRQ and complain it doesn't work, but I guess you must call NVIC_EnableIRQ somewhere... perhaps the delay plays with the interaction of NVIC_EnableIRQ and the...
yes, read it carefully the parameter is a number. I deleted my previous post to avoid ...
