[NMEA] GPS¶

Description¶

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.

Usage¶

This is a single-screen app, and a few interactions are provided via the hardware buttons:

• Long press the up button to change the baud rate. The default baud rate is 9600, but 4800, 19200, 38400, 57600, and 115200 baud are also supported.
• Long press the right button to change speed units from knots to kilometers per hour.
• Press the OK button to set the backlight to always on mode. Press it again to disable.
• Long press the back button to exit the app.

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.
