-
-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.
