WNMEA - Warcomeb NMEA 0183 Parsing Library

This library is developed in order to parse NMEA0183 string produced by GPS sensor and it use libohiboard as low level driver framework. This library is an evolutions of https://github.com/warcomeb/gpsnmea-embedded.

ChangeLog

• v1.0.0 of 2022/03/04 - First release

External Library

The library use the following external library:

• libohiboard https://github.com/ohilab/libohiboard a multiplatform C framework for multi microcontroller.

Example

void cb (WNMEA_MessageParsed_t msg, WNMEA_MessageType_t type)
