inav-follow-me | Follow me gadget based on Rpi Pico MCU

inav-follow-me is a Go library typically used in Internet of Things (IoT) applications. inav-follow-me has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Simple 'follow me' application for INAV. The application runs on a RaspberryPi Pico (rp2040) and requires a NMEA GPS connected to the Pico. The vehicle requires INAV firmware supporting MSPv2. This is an artificial requirement to simplify the code; the underlying INAV "follow me" functionality e.g. (GCS_NAV) has existed since 2016. A bi-directional MSP capable transparent serial data link is required between the ground control station (GCS) and the vehicle. Examples of suitable data links include 3DR, HC-12 and LoRA based radio systems. The RP Pico requires a GPS. An old NMEA capable Neo6M is more than adequate. It must provide $GPGGA and optionally $GPRMC. In theory, "follow me" is available for all types of INAV vehicle (platform type) that supports stationary POSHOLD, e.g. MultiRotor and possibly Rover and Boat. By default, fixed wing is excluded, but this can be changed by configuration. Optionally, a SSD1306 OLED will be supported (once the author's device is delivered).
