16-bit Embedded Control Solutions

Display & Touch

Many 16-bit designs are adding modern user interfaces

to increase the usability, functionality and look of end

products. More sophisticated displays and touch interfaces

create higher impact designs, yet must be easy to

integrate and cost effective. 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 family features integrated

segmented display driver 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 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,

flicker-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 & Sliders

Many PIC24 MCUs and dsPIC DSC products include touch

sensing capability for implementing keys or sliders as

an alternative to traditional push botton 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

Software & 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

■ Includes 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 (GDD X)

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.

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. Being a source-

code solution further helps engineers quickly integrate touch

sensing functionality with their existing application code in a

single, standard microcontroller.
