Olimex EKG/EMG with Mega

Has anyone got around to using the Olimex EKG/EMG with Mega? The boosterpack works with minimal changes, but the graphs are no where close to a typical cardio-plot. I have used the code from Github which I believe is more for the Due.


Is there some changes to the timer? By the way, I still used the old Electro Guru as recommended by Oilmex http://www.realization.org/page/topics/electric_guru.htm. The only configuration that worked for me was "BrainMaster" as the machine. Incidentally, the range set in the code is 0 to 1024, but the readings I get are in 100's.

Appreciate your help.
