<h1 id="bit-integer-arithmetic-for-avr">24 bit integer arithmetic for
AVR</h1>
<p>This library provides a 24-bit signed integer type,
<code>Int24</code>, for Rust. It is designed for use on AVR
microcontrollers.</p>
<h2 id="features">Features</h2>
<ul>
<li>24-bit signed integer type (<code>Int24</code>)</li>
<li>Saturating arithmetic operations: addition, subtraction,
multiplication, division</li>
<li>Bitwise operations: shift left, shift right</li>
<li>Specialized operations: Shift left and then divide</li>
<li>Comparison operations</li>
<li>Conversions to and from <code>i16</code> and <code>i32</code></li>
<li>Most operations are <code>const</code> or have a <code>const</code>
variant</li>
<li>All operations are highly optimized for speed and code size</li>
</ul>
<h2 id="usage">Usage</h2>
<p>To use the <code>Int24</code> type, add <code>avr-int24</code> as a
dependency to your <code>Cargo.toml</code></p>
<div class="sourceCode" id="cb1"><pre
class="sourceCode toml"><code class="sourceCode toml"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="kw">[dependencies]</span></span>

<p>and then use it in your code:</p>
<div class="sourceCode" id="cb2"><pre

<h2 id="rust-compiler">Rust compiler</h2>
<p>AVR inline assembly is not yet stabilized. Therefore, a
<code>nightly</code> Rust compiler is required.</p>
