How to implement the soft power on/off with PSOC I/O or capsense button? Is it possible to make it without external IC component?

best regards

不能通过capsense长按或者短按键来实现电源的通断, 但是可以每隔一段时间把系统唤醒,进行capsense的扫描,根据这个扫描的状态来判断要让系统进入active的状态,还是继续睡眠。 如果按键扫描满足某一个状态,我们也可以通过代码,让系统进入睡眠状态。 不清楚这样的系统是不是您想要的。

English:

It is not possible to turn on and off the power supply by pressing the CapSense key for a long time or short , but the system can be awake  by one fixed period , and the scanning state can be used to determine whether the system should be put into active state or continue to sleep.

If the key scanning meets a certain state, we can put the system into sleep state.

I am not sure whether such system can meet your requirement.

可以实现系统软件复位。

你需要详细的描述一下你想要做成的系统是什么样子,我们才能针对性的给你一些建议。

The system can achieve software  reset.

You need to describe in detail what kind of system you want to make ,then we can give you some suggestions.

我想利用capsense或按鈕去開機. 例如長按某鍵3秒開機.再長按5秒關機! 可以嗎?
