New 2D Touch Surface library for embedded applications
The new library is intended to help implement small touchpads and screens. It will eliminate costs by running on the system MCU, removing the need for a dedicated controller for touch functions. Microchip’s code configurators: MPLAB Code Configurator (MCC) for PIC MCUs and Atmel START for AVR and SAM MCUs, allow easy graphical configuration and output lean C code. The new library is available now for Atmel controllers, with the MCC version following later this quarter.
Low-power performance for touchpads is built-in through the library, as surfaces are scanned at once while in deep sleep. The solution provides continued responsiveness and functionality through the impact of water and noise. Implementations operate through wet conditions and can sustain 10V in conducted noise, in alignment with International Electrotechnical Commission (IEC) 61000-4-6 test level 3.
The DM080101 Water Tolerant Touch Surface development kit is available to enables developers to evaluate the new 2D Touch Surface library.
