title: What does this code mean？
body: <pre><code>while(1)
  { 
      for(x=0;x&lt;5;)   //note: x is incremented elsewhere 
      {
          DAC-&gt;DHR12R1 = (uint16_t)(x/5.0*4095*3.0/3.3);
      }
  }   
  </code></pre>
  
  <p>what does this loop mean？I know the DHR12R1 is data hold register 12bits right</p>
