Using with M0 processor #6

Closed trlafleur closed 5 years ago

trlafleur commented 5 years ago

The pre-declaration of RTC cause error with M0 processors as RTC is predefined in the Atmel CMSIS-Atmel libraries...

I might suggest: or leave it to the user to create the instance define in his program.

class MD_DS1307 RTCLOCK;  // one instance created when the library is included
