CapSense按钮可用于ON / OFF

我有一个要求睡觉和唤醒使用CAPSENSE按钮。这是可能的吗?当按下时,唯一可以运行的东西(几乎一切都处于睡眠模式)是唤醒的CAPSENSE按钮。

嗨,安得烈,
对。这是可能的。工作流程和你的想法非常相似。
如果没有触摸指定超时,该芯片将转向低速扫描模式。一旦联动按钮触动,该芯片将转向快速扫描(主动)模式。
我们有一些关于它的示例代码。例如:

谢谢,

  Hi Andrew,
 
Yes. It's possible. The work flow is much similar with your thought.
If there is no touch for a specified timeout, the chip will turn to low speed scan mode. Once the ganged button touched, the chip will turn back to fast speed scan(active) mode.
And we have some example code about it. For example:

Thanks,
Ryan
