Hallo hier ben ik terug
ik zit nog met een probleem
het splitsen van de graden van de minuten lukt mij niet helemaal
de graden heb ik nu apart maar bij de minuten krijg ik resultaat 0
ik ben nu nog niet met de conversie bezig ik probeer het eerst te splitsen
maar ik zit weer op een verkeerd spoor
kan iemand mij hierbij helpen ?
Groeten Gert
// Test code for Adafruit GPS modules using MTK3329/MTK3339 driver
//
// This code shows how to listen to the GPS module in an interrupt
// which allows the program to have more 'freedom' - just parse
// when a new NMEA sentence is available! Then access data when
// desired.
//
// Tested and works great with the Adafruit Ultimate GPS module
// using MTK33x9 chipset

// and help support open source hardware & software! -ada
