title: CANopen PDO sample code for LPC11Cxx
body: <p>I tested and understood SDO rx and tx with the LPC11Cxx demo. But this demo stack has only SDO functions and a driver <a href="http://en.wikipedia.org/wiki/Application_programming_interface" rel="nofollow">API</a>. I want to implement PDO for the same. What would be some sample code or implementation steps or functions?</p>
  
  <p>I want to send 68 (ADC data) bytes of data from a slave node to the master node at regular intervals. How can I do that?</p>
  
  <p>For the above task, is SDO better than PDO? How many PDOs do I need to send 64 bytes of data? How can I set PDO mapping and parameters? What is the difference between a master node and a slave node? How do I differentiate from code?</p>
