title: Steps to make a LED blink from a C/C++ program?
body: <p>What are the easiest steps to make a small circuit with an LED flash from a C/C++ program?</p>
  
  <p>I would prefer the least number of dependencies and packages needed. </p>
  
  <ul>
  <li>What port would I connect something into?</li>
  <li>Which compiler would I use?</li>
  <li>How do I send data to that port?</li>
  <li>Do I need to have a micro-processor? If not I don't want to use one for this simple project.</li>
  </ul>
  
  <p>EDIT: Interested in any OS specific solutions.</p>
