Double buffering</h1>
|
|
<p>When using interrupts, the system can sometimes exhibit "tearing" artifacts where half-finished images are displayed because an interrupt fired in the middle of a screen update.</p>
|
|
<p>This problem can be alleviated using double buffering: all rendering is done to an off-screen buffer that is swapped onto the screen once it is ready for display. Rendering then switches to the other buffer that is now off-screen. The following example demonstrates this:</p>

Multiple panels</h1>
|
|
<p>Multiple panels can be daisy-chained together using ribbon cables. If there is a single row of panels, then they must be connected to the Arduino board as follows:</p>
|
|
<div class="image">
|
|
<img src="dmd-4x1.png" alt="dmd-4x1.png"/>
|
|
</div>
|
|
<p>If there are multiple rows of panels, then alternating rows are flipped upside-down so that the short ribbon cables provided by Freetronics reach (this technique is thanks to Chris Debenham; see <a href="http://www.adebenham.com/category/arduino/dmd/">http://www.adebenham.com/category/arduino/dmd/</a> for more details):</p>

|
<div class="image">
|
|
<img src="dmd-4x2.png" alt="dmd-4x2.png"/>
|
|
</div>
|
|
<p>This technique can be repeated for as many rows as required, with the bottom row always right-way-up:</p>
