RTC (DS1307) probleem

Berichtdoor Petervd » 26 jan 2012, 15:06

Hoi,

Welligt kent iemand dit fenomeen:

Sinds de bouw van mijn eerste nodo (draadjes model) heb ik problemen met de RTC. In eerste instantie werkte alles zoals het zou moeten, maar na een hardware aanpassing (speaker) was er ineens geen clock meer. Aangezien ik niet zeker wist of ik misschien sluiting gemaakt zou hebben toch maar een nieuwe RTC besteld en omdat ik er roch nog een nodig had een extra mega.

Gisteren spulletje binnen gehad, maar wat ik ook probeer, geen clock. ook andere scktsches geprobeerd, maar geen resultaat. Ik weet niet meer zo goed waar ik moet gaan zoeken, iemand een idee?


alvast dank,

Peter

Niet wanhopen. :D

De klok loopt niet zonder batterij, ook al krijgt de chip voeding van de Arduino. Ook is het niet ondenkbaar dat het kristal niet werkt. Dan zou ik zeggen check...dubbelcheck.... Het is en kwestie van elimineren van mogelijke oorzaken.

Hint:
Meet de spanning eens die naar de RTC chip gaat, als deze te laag is doet RTC het ook niet.

Ik heb schijnbaar hetzelfde probleem met mijn MEGA2560 rev3.
RTC nu nog aangesloten op A4/ A5.
Moet ik die bij de MEGA niet gewoon aansluiten op D20/D21 ? Of moet er dan ook eea worden aangepast in de code ?
