RPI Waveshare Lib

This is a simple library for using the WaveShare L76x GPS hat for the Raspberry Pi.

The library turns on sensing and runs a background thread that parses the incoming serial messages and pushes them into a queue, from which the most recent message of a given type can be queried synchronously without blocking.

The API exposes the following methods:

Importing the Library

import waveshare

Start Serial Stream

start(device)

This starts the stream of serial data from the waveshare ("device" should be the name of the USB device being used to communicate with the waveshare). Prior to running this method, all getters will return None.

Stop Serial Stream

stop()

This stops the stream of serial data from the device. Until it is re-started, all getters will return the last value published by the device.

Read Data Packets

get_gga()

get_gsa()

get_gsv()

get_rmc()
