This is a fork of EZOD's FAP. https://github.com/ezod/flipperzero-gps

I have changed gps.c to show KPH for speed and N, E, S and W (and the betweens) for course. FAP has been compiled for API 11.2

I have tested this with a BN-180 GPS module I use for drone builds. Build video here https://youtu.be/MFM9TglyS0Y

GPS for Flipper Zero

A simple Flipper Zero application for NMEA 0183 serial GPS modules, such as the Adafruit Ultimate GPS Breakout.

Heavy lifting (NMEA parsing) provided by minmea, which is included in this repository.

Hardware Setup

Connect the GPS module to power and the USART using GPIO pins 9 (3.3V), 11 (GND), 13 (TX), and 14 (RX), as appropriate.

Building the FAP

1. Clone the flipperzero-firmware repository.
2. Create a symbolic link in applications_user named gps, pointing to this repository.
3. Compile with ./fbt fap_gps.
4. Copy build/f7-firmware-D/.extapps/gps.fap to apps/Tools on the SD card (directly or using qFlipper).

Contributing

This project was a learning exercise and is more or less "complete" from my perspective, but I will happily accept pull requests that improve and enhance the functionality for others.

Currently, the app only parses RMC and GGA sentences, and displays a subset of the data that fits on the screen. The UART is also hard-coded to 9600 baud. These limitations are largely driven by the GPS module I have to work with. A more elaborate UI with scrolling or multiple screens, as well as a configurable baud rate, may be useful for other GPS modules.
