Using IRLib2 for Lego Power Functions - examples available?

Hi,

I'm looking for examples (or protocol implementations) for the IRLib2 library to be used with the LEGO Power Functions. In particular I'd like to control 4 LEGO receiver (LEGO 8884) and want to implement the IR sender with an Arduino and a IR led.

I didn't found an example yet...

Any hints?

Thanks!

Regards Andreas
