Rudi Cilibrasi

Device driver for the modularEEG from the OpenEEG project.

So far protocols P2 and P3 are supported. (For details regarding these protocols see )

void eatCharacter (  unsigned char  c  )

this function does the real data processing of serial input data number of frames until protocol is locked in place to store eeg data has the protocol been detected and validated ? not yet, or error previously now it detected the frame, from now on the protocol is fixed check packet for validity ok, didmatch is 0, so it didn't match so far Definition at line 127 of file modeegdriver.c.
