error message

Hi,

after downloading “http://roboticcore.com/?p=53” (TeslaFan) and compiling, I get the message: CommManager.cpp 159 : error ‘PB1’ was not declared in this scope. I don’t find ‘PB1’ in any header file. Can you help me, please, to locate the error? What are the values of PB1 and PB2 in this context?

Thank you!
