GPS for Flipper Zero
Adafruit Ultimate GPS Breakout.
Heavy lifting (NMEA parsing) provided by minmea, which is included in this repository.
Modifications made by @xMasterX
- Ability to change baudrate using Up button, hold button to switch between baudrates (9600, 57600, 115200) (i set 57600 as default)
- Ok button will set backlight to always on mode, to disable press ok button again (it will restore default settings after app exit too)
- Exit from app using long press on back button instead of short press, may be useful in case you want to turn backlight on and accidentally click back
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.
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.
