Summary

This component interfaces with a U-Blox M8 GPS module over the I2C communication protocol. It processes satellite data to provide location, time, speed, and other navigation information.

Description

The U-Blox M8 GPS (I2C) component allows for easy integration of a high-precision GPS module. It communicates using the I2C bus, minimizing the number of required pins. The component decodes messages from the GPS to output structured data like latitude, longitude, altitude, speed, course, and satellite information.

Diagram:

Properties

• Enabled – Enables or disables the component.
• Base Year – Sets the base year (e.g., 2000) for correct date interpretation.
• Address (I²C) – Defines the I²C address of the GPS module.

Pins

Input Pins

• Reset (clock) – A clock signal on this pin resets the component.

Output Pins

Course

• Speed – Current ground speed (analog).
• Course – Current heading or direction of travel (analog).

Location

• Latitude – Latitude in degrees (analog).
• Longitude – Longitude in degrees (analog).
• Altitude – Altitude above sea level (analog).
• Height Above WGS84 Ellipsoid – Height relative to WGS84 ellipsoid (analog).
• Magnetic Variation – Magnetic variation in degrees (analog).

Satellites

• Count – Number of satellites in view (unsigned).
• Start Scan – Clock input to initiate satellite scanning.
• Satellite Number (PRN) – Satellite ID (unsigned).
