Hi,
    I tried modifying the sample TinyGPS shield sketch to write the encoded NMEA sentence to a file on a microSD card.  I think the problem is in the modified smartdelay routine that never finds a satellite fix....or a valid NMEA sentence.  Hardware I am running:
    TinyScreen+ processor
    TinyGPS Shield modified to have chip select pin set to 8
    Tiny SD microSD shield

    Anyone see the problem?
