led.toggle() sw.irq(trigger = machine.Pin.IRQ_RISING , handler = handle_interrupt)#Pin.irq(handler=None, trigger=(Pin.IRQ_RISING))#配置在引脚的触发源处于活动状态时调用的中断处理程序。如果引脚模式是, Pin.IN 则触发源是引脚上的外部值。 如果引脚模式是, Pin.OUT 则触发源是引脚的输出缓冲器。
rt_hw_cpu_id:最首先需要实现的一个也是最容易的实现的一个,直接访问pico的sio就可以 rt_hw_interrupt_disable/enable: 在SMP框架当中,关闭中断不只是屏蔽中断,其还要通过spinlock来保证对资源访问的互斥,对于此rtt在rthw通过宏定义将其替换,并且重新命名原来的中断控制函数 rt_hw_spin_lock_xxx:自旋锁,用于多核...

I want to trigger an interrupt when the FIFOs of a PIO become empty, There's loads of examples of interrupts in general in the pico-examples, but I can't see one explicitly for PIO. Here's an example chopped out of a working program. Note that I've declared the IRQ handler "not_...
