The GPUs are briefly explained below:

? CHRGPU: Renders the characters on the display.

A font table must be loaded into the RAM and the

CHRGPU must point to that font table. The (x, y)

coordinates must also be initialized on the appro-

priate CHRGPU registers. When a character code

and the draw command are given, the character

will be rendered on the configured RAM area,

which can also be the frame buffer. The user must

take care of the display glass orientation as the

characters cannot be rotated dynamically by the

CHRGPU. The CHRGPU does not support anti-

aliased fonts; all the pixels on a character are of the

same color. The background and foreground colors

are set using the CHRGPU commands. If transpar-

ency is enabled, only the foreground color is

drawn, and if the transparency is disabled, the

background color is also drawn surrounding the

character. To use the CHRGPU by default, uncom-

ment the line: #define USE_DRV_OUTCHAR in

MicrochipGraphicsModule.h .

? RCCGPU: Used to draw horizontal or vertical

lines, rectangles, filled rectangles, and to copy

rectangular regions. RCCGPU can perform the

following three operations:

- Copy – Copy a memory block from one part

of the RAM to another. Depending on the

command parameter, the block of memory

can be a contiguous block or a rectangular

block.

- Copy with Solid Fill – Fill a rectangular area

with a specific color.

- Copy with Transparency – Same as the copy

option, but a color set apart to indicate trans-

parency will not be copied to the destination,

leaving that part of the destination

unchanged.

Each operation can use one of the 16 available logical

operations, called Raster Operations (ROPs), which is

applied while copying.

For example, source can be copied as is or the source

can be ORed with the destination area, or the source

can be ANDed with a separate region and copied to the

destination area. For more information on the Graphics

Controller Module (GFX) and the supported ROPs,

refer to the Section 43. “Graphics Controller Module

(GFX)” (DS39731) in the “PIC24F Family Reference

Manual” .

The RCCGPU can be used to achieve special effects,

such as screen animations, like scrolling, peeling, etc.

For more information on the advanced usage of the

RCCGPU, see Appendix C: “Advanced Usage of

? IPU: Used to decompress a compressed data

using the DEFLATE algorithm with Fixed Huffman

codes. For example, images can be compressed

and kept in the internal Flash or external memory

and they can be decompressed into RAM during

run time. Similarly, compressed user-specific data

can also be decompressed and used during run

time with the IPU. It should be noted that

decompression can only commence from the

beginning of a compressed block and not from the

middle. For example, when storing multiple

images, compress each image to its own

compressed block. The IPU can be used to

decompress any images by specifying the

location of the desired compressed block. The

Microchip Graphics Library will handle this

scenario, making it transparent to the users.

Note: Bit maps can be compressed by selecting

the “IPU” option in the Graphics Resource

Converter (GRC) tool while converting the

images. GRC is a tool included in the

installation of the Graphics Library. The

PutImage() API automatically decom-

presses these compressed images using

the IPU at run time. The user is required to

allocate the required amount of RAM for

IPU operation, using compile-time options

as described in the Microchip Graphics

Library Help file.

For more information on these GPUs and their

registers, refer to Section 43. “Graphics Controller

Module (GFX)” (DS39731) in the “PIC24F Family

Reference Manual” .
