16-bit Embedded Control Solutions 11 Display and Touch Many 16-bit designs incorporate modern user interfaces to increase the usability, functionality and look of end products. More sophisticated displays and touch interfaces create higher impact designs, yet they must be cost effective and easy to integrate. Microchip’s solutions allow for driving segmented or graphical displays with a single chip and offer integrated peripherals for touch buttons. Segmented LCD Displays The PIC24FJ128GA310 and PIC24FJ128GC010 families feature integrated segmented display drivers with up to 480 segments. Key advantages include: ■ Direct drive of inexpensive, low-power displays ■ Integrated analog for sensor applications like temperature sensing in thermostats ■ Integrated touch sensing function for buttons or sliders Graphical Displays The PIC24FJ256DA210 family features integrated graphics acceleration and a display controller to directly drive displays up to 4.3" WQVGA with 480 × 272 resolution. This “DA” family includes: ■ Dedicated graphics clock for a continuous, fl icker-free display ■ On-chip display controller provides direct interface to TFT, STN and OLED displays ■ Easy to use graphics processing units for hardware acceleration allow for moving and copying rectangles, decompressing images and rendering text without CPU intervention ■ Integrated color look-up table and 96 KB frame buffer support up to 8 bpp QVGA with internal memory Touch Buttons: Keys and Sliders Many PIC24 MCUs and dsPIC DSC products include touch sensing capability for implementing keys or sliders as an alternative to traditional push button switches using CVD or CTMU technology. This enables more modern and stylish designs, lower manufacturing costs and increased reliability. ■ Longer battery life with eXtreme Low Power MCUs ■ Sensing through metal, plastic or glass ■ High noise immunity and low emissions ■ Free mTouch sensing solutions software library enables easy integration Development Tools LCD Explorer Development Board (DM240314) The LCD Explorer provides an ideal platform to evaluate a MCU with a × 8 Common LCD Driver on a 38 segment × 8 common LCD display. PIC24FJ256DA210 Development Kit (DV164039) This kit bundles the PIC24FJ256DA210 Development Board (DM240312), a 3.2" Truly 240 × 320 TFT Display Board (AC164127-4), three Graphics Display Prototype Boards (AC164139), the MPLAB ICD 3 Debugger (DV164035) and also includes a USB Cable and accessories. Remote Control Demo Board (DM240315-2) This board integrates graphics, mTouch technology, USB and RF4CE into a single demo. It features the PIC24FJ256DA210 MCU, a 3.5" Graphical TFT LCD with resistive touch screen, capacitive touch keys with plastic overlay, an MRF24J40 2.4 GHz transceiver and a ZENA™ wireless adapter. Software and App Notes FREE Microchip Graphics Library The Microchip Graphics Library is highly modular, easy to use and has an open documented interface for driver or controller support. The library supports the following features: ■ Pre-made graphics objects ■ Multiple fonts and languages ■ User interface for mTouch sensing ■ Buttons, charts, check boxes, scroll bars, list boxes, images and basic animation FREE Microchip Graphics Display Designer The Microchip Graphics Display Designer for MPLAB X IDE (GDD X) is a visual design tool that provides a quick and easy way of creating Graphical User Interface (GUI) screens for graphical interface applications on Microchip MCUs. mTouch Sensing Technology Source Code and Demos Microchip’s mTouch sensing solutions provide a free and easy method for designers to add capacitive touch sensing to applications utilizing PIC microcontrollers without the cost of fee-based licensing and royalty agreements. This sourcecode solution helps engineers quickly integrate touch sensing functionality with their existing application code in a single, standard microcontroller.
