Introduction
Capacitive sensor keyboards are widely used in modern compact devices. Each keyboard sensor can be connected to the individual microcontroller pin if number of used sensors is not large. Such connection scheme allows built the keyboard with up to 24 sensors on CY8C21434 microcontroller. If sensors number is larger than available microcontroller pins other keyboard structure should be used. One of the possible methods for solving th
