well the manual is not up to date, (sorry for that, but I had no time for updating) do you get any errors when you run the testlevel or the carlevel ( please download the latest version)? the testlevel uses almost all functions, check out if the pXent functions you are using are also in the c-lite files of the testlevel.
which part of the manual do you refer to?

Edit: search for the functions you are using in the pXent.h file! if it's not in this file, it is not correct.
