Hi,
I'm now using Capsense component on Psoc4s(CY8C4025LQS-S411).
When it wakes up from deep sleep, it sometimes works but sometimes doesn't.
I would appreciate it if you could help me.
Best regards,
ZONDAR

Hi @ZONDAR1
Please note that CapSense itself cannot be used to wake up a device from deep sleep. You need another wakeup source (typically a WDT so that you can wake up after a fixed time) so that the device is back to active mode and CapSense scan can be initiated.
The place to call this would be after PROCESS_DATA. Once the processing is complete and if the sensors are not active, you can enter deep sleep, keeping the WDT as a wakeup source.
This flow is explained in the CE210291 - PSoC® 4 CapSense® Low-Power One Button code example.
Best regards,
Hari
