This is a wrapper around libnmea, in the form of an ESP-IDF component. It works with any chip supported in ESP-IDF: ESP32, ESP32-S2, ESP32-S3, ESP32-C3.
There are two usage options:
idf.py add-dependency igrr/libnmea==required_version
in your project directory.OR
components
directory of your project,
or add it as a submodule.
See libnmea documentation
for more details.This component uses CMake build system. It works with ESP-IDF v3.3 and v4.x.
Example project is provided inside example
directory. It works the same way
as parse_stdin.c
example from libnmea, except that it reads NMEA sentences
from UART.
Connect the TXD pin of GPS receiver to GPIO21 of an ESP32 board. For other chips (ESP32-S2, ESP32-C3), change the pin number to any free GPIO.
Build and flash the example. Decoded NMEA messages will be displayed in the console.
