S1D13700_PartialImage
Prototype
procedure S1D13700_PartialImage(x_left, y_top, width, height, picture_
width, picture_height : word; const image : ^byte);
Returns Nothing.
Description Displays a partial area of the image on a desired location.
Parameters:
- x_left: x coordinate of the desired location (upper left coordinate).
- y_top: y coordinate of the desired location (upper left coordinate).
- width: desired image width.
- height: desired image height.
- picture_width: width of the original image.
- picture_height: height of the original image.
- image: image to be displayed. Bitmap array is located in code memory.
Note : Image dimension must match the display dimension.
Requires Glcd module needs to be initialized. See the S1D13700_Init routine.
Example
// Draws a 10x15 part of the image starting from the upper left corner on
the coordinate (10,12). Original image size is 16x32.
S1D13700_PartialImage(10, 12, 10, 15, 16, 32, image);
Flash Memory Library
This library provides routines for accessing microcontroller’s (internal) Flash memory.
The program Flash array for the PIC32MX device is built up of a series of rows. A row contains 128 32-bit instruction
words or 512 bytes. A group of 8 rows compose a page; which, therefore, contains 8 512 = 4096 bytes or 1024
instruction words.
A page of Flash is the smallest unit of memory that can be erased at a single time. The program Flash array can be
programmed in one of two ways:
- Row programming, with 128 instruction words at a time.
- Word programming, with 1 instruction word at a time.
The CPU stalls (waits) until the programming operation is nished. The CPU will not execute any instruction, or respond
to interrupts, during this time. If any interrupts occur during the programming cycle, they remain pending until the cycle
completes.
