Detailed Description

BicamGPS synthesizes NMEA GPS strings and uses the XPort serial port to send the GPS strings to the camera's GPS input port.

BicamTrigger triggers an image capture via the Lantronix XPort. Camera trigger is connected to XPort GPIO pins. BicamTrigger uses an XPort object to activate and deactivate the GPIO pins.
