3.8 Easy Tune

Easy Tune is enabled by default. The Easy Tune option saves development time by automatically adjusting the threshold based on the observed noise level, ensuring operations under changing noise environments while maximizing sensitivity if no or low noise is present. The Easy Tune feature controls threshold and oversampling(filter level) settings. Easy Tune automatically applies settings to satisfy the fundamental touch tuning recommendation from the Tuning Guide for Touch Sensors. With increasing sensitivity, increasing the oversampling is recommended to maintain noise robustness. If the user didn't adjust the oversampling accordingly, Easy Tune automatically adjusts to the recommended settings for robust operation. The minimum amount of recommended oversampling is applied with Easy Tune activated, or the user setting is used if selected higher than the minimum recommendation.

The threshold value will be reset to the previously saved value when this feature is disabled during runtime.

Example: The threshold for all buttons was set to 30 while the Easy Tune was disabled. This configuration has been stored in the device's memory. Upon enabling the Easy Tune feature, the threshold value will be dynamically adjusted according to the ambient noise level. If the feature is subsequently disabled, the threshold will reset to the previously stored value of 30 for all buttons.
