This class demonstrates how to program Microchip’s Graphics Library to add sophisticated graphics interfaces to embedded applications. At the end of this class the student will be able to include interactive graphics in a PIC® MCU application.
This class starts with a review of the components needed for graphics development. The tutorial then proceeds with an overview of a completed graphics application, describing all the software functions which need to work together to produce graphics applications. Engineers taking this tutorial are encouraged to first study the "Overview of a completed Graphics application" section to get an understanding of a working system. Once an engineer understands the program flow of a graphics application they can complete the tutorial by examining the individual graphics topics.
The class demonstrates the APIs first introduced in version v2013-12-20 of the MLA and in MPLAB® Harmony. While this tutorial does not include lab exercises, users of this tutorial are encourage to implement the code examples on their target board.
