how does this specific line of code work? 

 
#define HRM_FLAG_MASK_HR_VALUE_16BIT (0x01 &amp;lt;&amp;lt; 0) /**&amp;lt; Heart Rate Value Format bit. */

It is just standard &amp;#39;C&amp;#39; syntax - nothing specific to ARM or
microcontrollers - so you should simply look it up in your &amp;#39;C&amp;#39;
textbook.&lt;/p&gt;

&lt;p&gt;
Here are some &amp;#39;C&amp;#39; reference &amp;amp; learning resources - including a
free online textbook:&lt;/p&gt;

That line of code doesn&amp;#39;t &amp;quot;work&amp;quot;, as such, because it doesn&amp;#39;t
actually perform any job. It just gives a name to numeric
constant.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
