Hello,

To use this example, you need a different version of pyrpl which is now on a different github branch (https://github.com/lneuhaus/pyrpl/tree/modif_fpga_pfd). Note that there is a mistake and the name of the branch is actually "modif_fpga_pfd". You can use git to switch branch or download the code of the branch and replace the files on your computer. Good luck !
