Dzięki
lotpawel za podpowiedzi :)
po pierwsze - czy sam gps łapie fixa? w domu, pod dachem może nie łapać. Podłącz gps do kompa i sprawdź,
Tak, GPS łapie zasięg (sprawdzam na balkonie).
Podłączyłem go bez modułu I2C-GPS bezpośrednio po serialu do Arduino Uno i działał OK.
Komunikował się z UNO z prędkością 9600.
po drugie - i2c-gpsnav czy masz wgrany dobry fw? z odpowiednimi ustawieniami, prędkością portu, rodzajem gps itp itd?
Tego właśnie nie robiłem bo do tej pory nie miałem o tym wiedzy, że trzeba to skonfigurować :)
po trzecie - czy masz odblokowana funkcje gps i2c w multiwii?
Czy tak powinno być to zrobione jak w kodzie poniżej?
