标题: NRF51822休眠唤醒如何实现？ [打印本页] 作者: sps 时间: 2016-8-18 23:18 标题: NRF51822休眠唤醒如何实现？ 目前有一块板子，只有一个复位键。现在把复位键接到一个空的I/O口，没有连接复位引脚。请问休眠唤醒怎么做。我可以设置当按键按下时，CPU进入休眠，可唤醒信号怎么给呢。只有一个按键。可以通过miniUSB插入唤醒吗，可是又担心会影响充电功能。 作者: hxy1596 时间: 2016-8-19 09:08
可以用定时器控制休眠，按键唤醒。。。。作者: hxy1596 时间: 2016-8-19 09:09

System OFF is the deepest power saving mode the system can enter. In this mode, the system’s core
functionality is powered down and all ongoing tasks are terminated. The only mechanism that is functional
and responsive in this mode is the reset mechanism.
One or more blocks of the RAM can be retained in System OFF mode depending on the settings in the
RAMON register.
The system can be woken up from system OFF mode either from the DETECT signal generated by the GPIO
peripheral, or from a reset. When the system wakes up from OFF mode, a system reset is performed.
文档里面有说，两种方式唤醒。一种是把你的IO口接reset，另外一种设置你的这个IO口去检测DETECT signal 作者: admin 时间: 2018-4-4 19:12
