蜂窝通信模组进入休眠模式后,有多种模式可以唤醒模组,包括网络数据、电话、GPIO 中断、Timer等,各种方式实际上都是通过中断来唤醒系统。 Soc 唤醒机制# 模组的休眠状态可以由任意中断唤醒(前提是有效的,部分中断控制器处于功耗考虑也会被关闭),唤醒后会在临界区中恢复设备上下文。此时中断控制器中存有此中断的标志,但是...
A callback can be used for notifications. For instance, you need to set a timer in your application. Each time the timer expires, your application must be notified. But, the implementer of the time'rs mechanism doesn't know anything about your application. It only wants a pointer to a ...
