Liquid Tolerant Capacitive Touch Keypad Reference Design
Description
The Liquid Tolerant Capacitive Touch Keypad Design (TIDM-1021) is a reference design for implementing liquid tolerant capacitive touch human-machine interfaces (HMIs). It integrates TI's MSP430FR2633 microcontroller (MCU) featuring high performance CapTIvate™ touch technology with an optimized sensor layout design and software. This reference design demonstrates how to design capacitive touch hardware and software that can work reliably under liquid influence and pass challenging tests for conductive noise immunity.
Features
