Regarding PSoC4S sample project using guard sensor.

[YuMa_1534086]

Hello.

Q1)

Is there PSoC4S sample project using guard sensor?

Please provide it if there is it.

Q2)

Could you please let us know FW development procedure when guard sensor is implemented?

CSD component(above V3.x) has not widgets for guard sensor.

Should user add normal button sensor as guard sensor if they use guard sensor?

And should user add code to main.c about PSoC behavior after guard sensor touch status becomes “1”, according to their design specification?

And there is no API and component configure setting for guard sensor, right?

Best Regards.

Hi YuMa_1534086​,

Guard sensor should be treated as a normal CapSense sensor. It should be tuned in such a way that it is triggered only when there is a stream of water present in the board where there are CapSense sensors. The firmware should be written  bu the user in such a way that when the guard sensor is triggered ('1'), all the other sensors should be disabled (shouldn't be scanned) except guard sensor.

Dear Bragadeesh-san.

Is there PSoC4S sample project using guard sensor?

I do not know the recommended code processing when using guard sensor.

Should be button sensor scan itself stopped when guard sensor’s touch status becomes “1”?

Or is it OK that user only ignore all button sensors data without stopping button scan while guard sensor’s touch status becomes “1”?

And how should user handle button sensor when guard sensor’s touch status returns to “0” from “1”?

Should baseline initialize once before starting button scan when guard sensor’s touch status returns to “0”? etc.

Please provide recommended scan method, scan flow and sample project etc, when using guard sensor.

Best Regards.
