\page dmd_running_figure Running figure example
|
||||
|
||||
This example demonstrates how to draw animated bitmaps to
|
||||
<a href="http://www.freetronics.com/dmd">Freetronics Large Dot
|
||||
Matrix Displays</a>. These displays have 512 LED's arranged in a
|
||||
32x16 matrix and controlled by an SPI interface. The displays are
|
||||
available in red, blue, green, yellow, and white variations.
|
||||
|
||||
The first step is to initialize the display:
|
||||
|
||||
\dontinclude DMD/examples/RunningFigure/RunningFigure.pde
|
||||
\skip #include
|
||||
\until DMD display;
|
||||
|
||||
We will also need some bitmaps to animate the running figure. We will use
|
||||
static bitmaps stored in program memory. The first frame of the 10-frame
|
||||
animation is:
|
||||
|
||||
\dontinclude DMD/examples/RunningFigure/RunningFigure.pde
|
||||
\skip run1
|
||||
\until };
|
||||
|
||||
As can be seen, the bitmap is made up of 0's and 1's; a 1 bit indicates that
|
||||
the corresponding LED will be lit when it is drawn to the dot matrix display.
|
||||
The first two bytes are the width and height of the bitmap in pixels.
|
||||
In this case, the first frame is 16x16 pixels. Other frames in the animation
|
||||
are 18x16 and 13x16.
|
||||
|
||||
We store pointers to all of the frames in a common array:
|
||||
|
||||
\dontinclude DMD/examples/RunningFigure/RunningFigure.pde
|
||||
\skip frames[]
|
||||
\until frame = 0
|
||||
|
||||
All that remains is to run the animation loop:
|
||||
|
||||
\dontinclude DMD/examples/RunningFigure/RunningFigure.pde
|
||||
\skip ADVANCE_MS
|
||||
\until display.loop()
|
||||
\until }
|
||||
|
||||
Each time \c ADVANCE_MS milliseconds expires, we clear the display and
|
||||
draw a bitmap centered on the screen. To help with the centering, we read
|
||||
the width value from the bitmap for the current frame (the height is
|
||||
always 16). We must also call DMD::loop() repeatedly from the application's
|
||||
main <tt>loop()</tt> function to ensure that the display is kept refreshed.
|
||||
|
||||
Sometimes it can be inconvenient to arrange for DMD::loop() to be called
|
||||
regularly. An alternative is to use Timer1 and
|
||||
\ref dmd_interrupts "interrupt-driven display refresh":
|
||||
|
||||
\dontinclude DMD/examples/RunningFigureISR/RunningFigureISR.pde
|
||||
\skip ADVANCE_MS
|
||||
\until loop()
|
||||
\until }
|
||||
|
||||
