* Charge and discharge times of one measurement: :cpp:func:`touch_pad_set_charge_discharge_times`
Relationship between the voltage range (high / low reference voltages), speed (slope), and measurement time is shown in the figure below.

Touch pad - relationship between measurement parameters
The last chart *Output* represents the touch sensor reading, i.e., the time taken to accumulate the fixed number of cycles.
All functions are provided in pairs to *set* a specific parameter and to *get* the current parameter's value, e.g., :cpp:func:`touch_pad_set_voltage` and :cpp:func:`touch_pad_get_voltage`.

触摸传感器 - 测量参数之间的关系
上图中的 *Output* 代表触摸传感器读值，即固定充放电次数所需的时间。
所有函数均成对出现，用于设定某一特定参数，并获取当前参数值。例如：:cpp:func:`touch_pad_set_voltage` 和 :cpp:func:`touch_pad_get_voltage`。
