 &lt;p>When using bits and bytes to control electronic components, the conversion from a byte to, e.g., logging output can be a bit confusing as Java uses signed values. This means a byte value has a range of -128 till 127, while you would expect 0 (0x00) till 255 (0xFF).&lt;/p>
 &lt;p>For example, the hex value &lt;code>0x8F&lt;/code> (&lt;code>10001111&lt;/code>) is handled like this:&lt;/p>
 &lt;div class="highlight">&lt;pre tabindex="0" style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4;">&lt;code class="language-java" data-lang="java">&lt;span style="display:flex;">&lt;span>&lt;span style="color:#66d9ef">var&lt;/span> b &lt;span style="color:#f92672">=&lt;/span> (&lt;span style="color:#66d9ef">byte&lt;/span>) Integer.&lt;span style="color:#a6e22e">parseInt&lt;/span>(&lt;span style="color:#e6db74">&amp;#34;10001111&amp;#34;&lt;/span>, 2);
