  • Inductive Touch - Configuring LDC2114 Touch-Button Sensitivity
    PDF, 771 Kb, Datei veröffentlicht: Mar 16, 2017
    Erroneous or unintended button presses can result in a frustrating user experience in a human machine interface (HMI). Capacitive touch buttons trigger anytime a grounded object is brought close to the button; this can often cause false or erroneous button presses. One advantage mechanical buttons have over capacitive touch buttons is that a certain amount of force must be applied on the buttons f
