mTouch Sensing Solutions: Touch Screen Controllers Projected Capacitive Technology Development Tools for Projected Capacitive Touch Microchip’s projected capacitive technology is the first in a series of patent-pending releases supporting projected capacitive touch screen solutions across the portfolio of 8-, 16- and 32-bit PIC MCUs.
Display Controller Solutions: Segmented LCD Display Solutions for Segmented LCD Direct Drive for Segmented Displays The LCD PIC microcontrollers support direct LCD panel drive capability with no external components needed, lowering total system cost. They have integrated voltage bias generation which allows the MCU to generate the different voltage levels that are required to drive the LCD segment pins and provide good contrast for the display.
Display Controller Solutions: Graphical Displays FREE Microchip Graphics Display Designer The Microchip Graphics Display Designer (GDD) is a visual design tool that provides customers with a quick and easy way of creating Graphical User Interface (GUI) screens for graphical interface applications on Microchip MCUs. Microchip offers varying levels of solutions to drive everything from simple monochrome LCDs to full color WVGA user interfaces.
