title: is it possible write to console without stdlibs? c/c++
body: <p>I am programming on an arm microprocessor and am trying to debug using print statements via UART. I do not want to add <code>stdlibs</code> just for debugging. Is there a way to print to the console without <code>stdio.h</code>/<code>iostream.h</code> ? Is it possible for me to write my own <code>printf()</code>?</p>
  
  <p>Alternatively I can do this using a DMA controller and writing to the UART directly. However I would like to avoid that is possible. Using the built in test function "echo" or 
  "remote loop-back" I know I have the UART configured properly.</p>
