Using PIC32 MCUs to Develop Low-Cost Controllerless (LCC ...
2011-2014 Microchip Technology 1AN1387 INTRODUCTIONAs the demand for Graphical Embedded Applicationsbecomes more popular, so does the need fordeveloping cost effective solutions. Today, manycompanies offer solutions involving an additionalinternal or external graphics controller as part of asystem, which may result in higher costs and morecomplicated designs. In most cases, for a simpleembedded Graphical User Interface (GUI), thesegraphics controllers are not necessary, but a suitablesolution may not be available. One solution that isbecoming more popular is to use a controllerlesssolution. This solution uses microcontroller (MCU)peripherals to create a virtual graphics controller forgraphics rendering without taking up large amounts ofCPU time (in this solution less than 5%).
