Python driver for fixposition gps
NOTE: work-in-progress
Currently these messages are supported: GGA,HDT,ODOMETRY
Functionality overview
parser.parse(msg: str, ignore: List[str] = []) -> FPX_Message | None:
- parse NMEA message to a NamedTuple- record and replay messages with
fixposition
cli - use
gps_node.FpxNode
class as async node to interface with fixposition device over socket.
Usage
Message parsing:
from fixposition import parser
msg = "$GPHDT,61.7,T*05\r\n"
data = parser.parse(msg)
CLI tool
This package provides a command-line tool fixposition
:
Usage: fixposition [OPTIONS] COMMAND [ARGS]...

--help Show this message and exit.
Commands:

How it works
- message definitions are in
fixposition.messages
. Each submodule contains aparse()
function. @validate_checksum
decorator adds nmea checksum to parse function.parser.parse(msg)
returnsNamedTuple
of a message
See .messages
code, extending this should be easy.
