class pygarmin.garmin.Garmin(physicalLayer)

Bases: object

Garmin GPS device object.

The class provides methods to communicate with the hardware.

Most GNU/Linux distributions use a kernel module called garmin_gps to make a USB Garmin device accessible via a serial port. In order to communicate with a Windows computer via a serial link, Garmin USB drivers need to be installed. To communicate with a Garmin device connected to the serial port /dev/ttyUSB0, you could try this:

>>> from pygarmin import garmin, link
>>> port = '/dev/ttyUSB0'
>>> phys = link.SerialLink(port)
>>> gps = garmin.Garmin(phys)
>>> print(gps.product_data)

Alternatively, internal USB support can be used. For this to work on GNU/Linux, you probably should remove and blacklist the garmin_gps kernel module.

>>> from pygarmin import garmin, link
>>> phys = link.USBLink()
>>> gps = garmin.Garmin(phys)
>>> print(gps.product_data)
