Touch sensor waterproof configuration

Aliased Type

}

Fields

guard_ring_pad: u32

<Waterproof. Select touch channel use for guard pad. Guard pad is used to detect the large area of water covering the touch panel.

shield_driver: u32

<Waterproof. Shield channel drive capability configuration. Shield pad is used to shield the influence of water droplets covering the touch panel. When the waterproof function is enabled, Touch14 is set as shield channel by default. The larger the parasitic capacitance on the shielding channel, the higher the drive capability needs to be set. The equivalent capacitance of the shield channel can be estimated through the reading value of the denoise channel(Touch0).
