Hello, team,
Currently, we have used the cap sense button for the ON/OFF switch for our gateway product. one time press for on and second-time press then hub should off.
In the current design, our cap sense pad design(OD:12mm Dia and ID:10mm Dia circle) RGB led is the center of the pad on the same side, and spring is soldered to a cap sense pad and connected to our plastic enclosure.
now we are moving forward to TI Liquid tolerance design with MSP430FR2512 ic.
we need below queries for Liquid tolerance cap sense design.
1) can we use two spring for TX and RX electrode in our design for mutual capacitance technology? Please suggest because we are not planning to change on the mechanical side.
2) can we place RGB led inside of the pad on the same side in PCB?
3) can we use (self capacitance+Hatch ground) connected with Capsense GPIO for Liquid tolerance design?
Please reply to the above queries ASAP.
