I have a requirement to sleep and wake using a CapSense button. Is this possible? When pressed the only thing that can be running (almost everything is in sleep mode) is the CapSense button to wake.
Solved! Go to Solution.

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
