## 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)

- Long press Right button to change speed from knots to kilometers per hour

- 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
2022-10-28 16:23:02 +00:00
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.
