The 2D Surface Touch Library is ideal for small touch panels and displays, eliminating costs by working with the device's existing microcontroller. This removes the need for a dedicated touch controller, giving designers the flexibility to add finger position tracking and gesture detection, such as swiping, pinching, and zooming, to their products. This touch library is delivered through Microchip's MPLAB® Code Configurator (MCC) for PIC microcontrollers and Atmel START for AVR and SAM microcontrollers. Both software tools simplify graphical configuration and accelerate development with optimized C code tailored to project requirements. The 2D Surface Touch Library is available now for Atmel START and will be available for MCC this quarter.
Intuitive and engaging user interfaces are crucial to product success, and the 2D Surface Touch Library doesn't require integrating an expensive operating system to meet consumer expectations for a smartphone-like interface. The library is well-suited for adding touch sensing to various applications in the consumer electronics, automotive, and industrial sectors, such as smart speakers, steering wheels, and thermostats.
The low power consumption of the touch panels is achieved thanks to the library, as the entire surface is scanned in a single pass while in deep sleep mode. Reliability is a fundamental requirement for touch detection, and the solution continues to function even in the presence of water and noise, thus meeting the demands of automotive and household appliance applications. They can operate in humid environments and can withstand 10V of conducted noise, as required by IEC (International Electrotechnical Commission) 61000-4-6, test level 3.
Development Tools
The DM080101 development kit for watertight touch surfaces facilitates the evaluation of the 2D surface touch library. The kit demonstrates its water resistance and noise immunity on a touch panel with two touch buttons controlled by the same controller.
Pricing and Availability:
The 2D surface touch library is available free of charge with the purchase of any compatible microcontroller. The DM080101 Sealed Touch Surface Development Kit is now available as a sample and in volume production.
