Google for the PC pinout;

Look at the board schematic for the board pinout;

Take care to understand which are inputs and which are outputs (don't just assume that ''RX'' means input - it doesn't necessarily);

You should be able to take it from there...

STM324x9I-EVAL board?

Just connect them together?
