Do you want to change how you interact with the world? Here’s how you can make a sleek capacitive touch remote control to control everything around you, from TV and set-top boxes to appliances, white goods and industrial control panels
Capacitive touch as a human-machine interface (HMI) technology is finding its way into more and more applications. It is rapidly becoming a popular technology for mechanical button replacement in end equipment such as small and large
home appliances, industrial control panels and automotive center stacks.
While capacitive touch interfaces offer convenience and appeal, they bring up new challenges. They are inherently susceptible to many different types of noise, posing serious challenges to designers looking to integrate capacitive touch into products that require a high level of reliability. Thus, designers need to tackle harsh environmental conditions such as heat, cold, high humidity, dirt, etc. Designers also need to minimize the power consumption of the design in order to extend battery life.
Noise-tolerant Capacitive touch HMI
This capacitive touch remote reference design from TI helps designers implement noise tolerant capacitive touch human-machine interfaces (HMIs). It integrates TI’s MSP430FR2633 microcontroller (MCU) featuring high-performance CapTIvate touch technology with the TPS7A4533 linear regulator and UCC28910 flyback switcher.
