title: Convert a long hex string in to int array with sscanf
body: <p>I have an input like</p>
  
  <pre><code>char *input="00112233FFAA";
  uint8_t output[6];
  </code></pre>
  
  <p>What is the easiest way to convert <code>input</code> into <code>output</code> with <code>sscanf</code>? (prefer 1 line with no loop) The solution I have in mind doesn't scale to 20+ hex string.</p>
  
  <pre><code>sscanf(input, "%x%x%x%x%x",output[0], output[1]....output[5]);
  </code></pre>
