Configure Your Touch-Enabled Device
MPLAB® Code Configurator (MCC) makes it easy to configure the code for any of our touch-enabled PIC®, AVR®, SAM and dsPIC33 devices. MCC is updated regularly as the touch features for device families evolve or as we launch new, innovative products. Our MCC Touch Features Overview provides more details on the touch features supported for each family of products. We also offer step-by-step instructions for getting started with MCC.
Other Resources for Getting Started With Touch Projects
Touch Examples
MPLAB Discover is a catalog of fully configured and complete source code, projects, examples and software applications. Use it as your starting point for your touch projects
Touch Evaluation Kits
Use a touch evaluation kit out-of-the box or mix and match Curiosity Nano boards to quickly start your prototyping.
Touch Visualization and Tuning
Validation is essential for touch projects. Our touch library offers built-in touch visualization and real-time tuning for your designs.
Capacitive Touch Applications
While buttons for user interfaces are the most common implementations of capacitive touch, there are many other use cases for capacitive touch sensing. Our touch solutions are leading the way in many new capacitive touch applications.
Functional Safety Touch
Functional safety is essential in many markets. Automotive functional safety requirements are governed by ISO 26262. Our Functional Safety Touch Library reduces your development time and effort for a variety of automotive applications, including:
- Cruise control on steering wheels
- Hazard buttons
- Mirror control clusters
Hands-Off Detection
Advanced Drive Assistance System (ADAS) uses Hands-Off Detection (HOD) to verify that a driver's hands are on the steering wheel. We offer a complete, single-chip HOD solution to speed up your implementation and shorten your time to market.
Watch our Hands-off Detection (HOD) Demo video.
Radiant Heating
Radiant heating is more efficient than traditional car heating systems. Our touch solution for radiant heating controls can help you design an EV heating system that quickly brings the cabin temperature up to comfortable levels.
Car Door Handles and Controls
Touch-based user interfaces aren’t only restricted to a car’s interior. We provide dedicated touch solutions to enable Near Field Communication (NFC) in door handles or to create touch buttons to open a car door.
Watch our Water-Resistant Touch Technology Demo.
Digital Level Sensing
Our capacitive Digital Level Sensing (DLS) solution senses the levels of liquids, eliminating the need for a floating element and the complexities of a mechanical solution.
Touchpads With Gestures
A touchpad can provide users with an easy and intuitive way to control their devices. Discover how easy it is to add a touchpad to control your new product.
