    • The present disclosure describes apparatuses and techniques for programmatic sensing of capacitive sensors. In some aspects, a first set of instructions are executed that drive an output to a predetermined state for a duration of time effective to charge a capacitive sense element, a second set of instructions are executed that monitor a voltage level of the capacitive sense element, the second set of instructions executed for a number of iterations until the voltage level of the capacitive sense element crosses a predefined threshold, and user interaction with the capacitive sense element is determined based on the number of iterations that the second set of instructions execute.
    • 本公开描述了用于电容式传感器的编程感测的装置和技术。 在一些方面,执行第一组指令,其将输出驱动到预定状态持续时间以有效地对电容性感测元件充电,执行监视电容性感测元件的电压电平的第二组指令, 执行多次迭代的第二组指令,直到电容检测元件的电压电平与预定阈值相交,并且基于第二组指令执行的迭代次数确定与电容检测元件的用户交互。
