Text input: Supports virtual keyboard input, handwriting input, and other methods, providing a convenient text input experience.
Smart door locks have become an essential component of modern home security, with touch technology playing a pivotal role in their functionality.
The processing stage is the stage in which the capacitive touch chip converts the sensed charge signal into an electrical signal and performs corresponding processing.
High sensitivity: Capacitive touch chips can sense small changes in charge, making them highly sensitive to touch operations.
MCU capacitive touch sensing technology is a common PCM1802DBR touchscreen technology widely used in electronic products such as smartphones
Specifically, the control circuit first samples the capacitive sensor by periodically measuring the voltage between the capacitive electrode and the reference electrode.
