Dot Matrix Display Demo
+
+
+

This demo shows off various features of drawing with the Bitmap class to a DMD display:

+
    +
  • Drawing circles, lines, and rectangles.
    • +
  • Filling the screen with a bitmap-based brick pattern.
    • +
  • Drawing bitmaps directly from program memory.
    • +
  • Drawing text in various fonts.
    • +
  • Scrolling text in a "marquee".
    • +
+

RunningFigure provides another example of drawing and animating bitmaps.

+

The full source code for the demo follows:

Running figure example
+
+
+

This example demonstrates how to draw animated bitmaps to Freetronics Large Dot Matrix Displays. 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:

+ 
#include <DMD.h>
+
+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:

+ 
byte const run1[] PROGMEM = {
+    16, 16,
+    B00000000, B00001100,
+    B00000000, B00011110,
+    B00000111, B11111110,
+    B00001111, B11111110,
+    B00011100, B11111100,
+    B00000001, B11111100,
+    B00000001, B11110000,
+    B00000011, B11111000,
+    B00000111, B00011000,
+    B00001110, B01110000,
+    B00011100, B01100000,
+    B00111000, B00000000,
+    B01110000, B00000000,
+    B01100000, B00000000,
+    B01000000, B00000000,
+    B00000000, B00000000
+};
+

+

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:

+ 
const prog_uint8_t *frames[] = {
+    run1,
+    run2,
+    run3,
+    run4,
+    run5,
+    run6,
+    run7,
+    run8,
+    run9,
+    run10
+};
+#define NUM_FRAMES  (sizeof(frames) / sizeof(frames[0]))
+unsigned int frame = 0;
+

+

All that remains is to run the animation loop:

+ 
#define ADVANCE_MS  (1000 / NUM_FRAMES)
+unsigned long lastFrame;
+
+void setup() {
+    lastFrame = millis() - ADVANCE_MS;
+}
+
+void loop() {
+    if ((millis() - lastFrame) >= ADVANCE_MS) {
+        display.clear();
+        int x = (32 - pgm_read_byte(frames[frame])) / 2;
+        display.drawBitmap(x, 0, frames[frame]);
+        lastFrame += ADVANCE_MS;
+        frame = (frame + 1) % NUM_FRAMES;
+    }
+    display.loop();
+}
+

+

Each time 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 loop() 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 or Timer2 and interrupt-driven display refresh:

+ 
#define ADVANCE_MS  (1000 / NUM_FRAMES)
+
+ISR(TIMER1_OVF_vect)
+{
+    display.refresh();
+}
+
+void setup() {
+    display.enableTimer1();
+}
+
+void loop() {
+    display.clear();
+    int x = (32 - pgm_read_byte(frames[frame])) / 2;
+    display.drawBitmap(x, 0, frames[frame]);
+    frame = (frame + 1) % NUM_FRAMES;
+
+    delay(ADVANCE_MS);
+}
+

+

In the case of Timer2, TIMER2_OVF_vect and enableTimer2() would be used in place of TIMER1_OVF_vect and enableTimer1().
