Getting Started: Running the “Graphics
SSD1926 JPEG and SD Card Demo”
The
demo projects are created to run on supported Microchip Demo Boards and
development hardware. Pre-generated hex files are available on the
"Precompiled Hex" sub-directory found in the demo directory. These
hex files are generated using the alternative hardware profiles found in the
sub-directory named "Configs". Use the "Demo Compatibility
Guide" when running pre-generated hex files appropriate for your
hardware.
The
demo uses the Microchip Memory Disk Drive File System (MDDFS) Interface Library
with the Microchip Graphics Library working on the Graphics PICtail™ Plus Board
Version 3 (AC164127-3) mounted with the SD Card slot. JPEG images stored in the
SD Card is displayed on the screen using the built in JPEG decoders in SSD1926
controller. The PIC microcontroller running the demo manages the display set up
and sequencing the images on the screen.
The
demo works with 8-bit and 16-bit (PIC32 only) PMP interface. To use 16-bit bus
the USE_16BIT_PMP compile time option must be uncommented in GraphicsConfig.h.
All display orientations are supported. Currently high capacity cards are not
supported (SD should be less than 2GB). Resolution of the images must be less
than 2560x1920 (maximum scale down factor is 8). The card must be inserted
before the demo starts.
