    Hi Folks,

    I'm trying actually to get an issue with the modEEG of the OpenEEG Project.
    When I plug the harware trough an serial/usb to PD (comport), I've a series of decimal numbers (to 256).
    On the firmware info (from BrainBay manual):

    "The P2 Firmware Protocol was the inital transmission protocol of the OpenEEG project, used by ModularEEG. It is compatible with the ElectricGuru application. P2 uses 17 data bytes to transmit 6 channels of EEG data:

    1: sync0; // synchronisation byte 1 = 0xa5
    2: sync1; // synchronisation byte 2 = 0x5a
    3: version; // version number = 2
    4: count; // packet counter. Increases by 1 each packet.
    5: Chn1low // channel 1 low byte
    6: Chn1high // channel 2 high byte
    7: Chn2low // channel 2 low byte
    8: Chn2high // ...
    9: Chn3low
    10: Chn3high
    11: Chn4low
    12: Chn4high
    13: Chn5low
    14: Chn5high
    15: Chn6low
    16: Chn6high // channel 6 high byte
    17: switches; // State of PD5 to PD2, in bits 3 to 0. "

    Could someone help me decrypting this firmware?
    Does somebody had use before the modEEG with Puredata?
