Suitable to implement small touch pads and screens, the 2D Touch Surface library eliminates costs by running on a device’s existing MCU. This removes the need for a dedicated touch controller, giving product designers the flexibility to add finger position tracking and gesture detection, such as swipes, pinch and zoom, to products. The touch library is provided through Microchip’s code configurators: MPLAB Code Configurator (MCC) for PIC MCUs and Atmel START for AVR and SAM MCUs. Both software tools enable simplified graphical configuration and accelerate development with lean C code tailored for individual project needs. The 2D Touch Surface library is available today on Atmel START and will be available on MCC this quarter.
Low-power performance for touch pads is built-in through the library, as complete surfaces are scanned at once while in deep sleep. The solution provides continued responsiveness and functionality through the impact of water and noise, meeting the demands of automotive and home-appliance applications. The DM080101 Water Tolerant Touch Surface development kit enables easy evaluation of the 2D Touch Surface library. The kit demonstrates water tolerance and noise immunity on a touch pad and has two touch buttons, all controlled by the same MCU.
