 		 #36151 - RE: RTC PCF8563 Source code
Michael

Do you know if there are any I2c pre calibrated RTC's with the xtal and battery built in ..
I'm currently using the DS1307 (and have tried the PCF8563,and Xicor x1226s) and there all woefully innacurate unless the crystal load capacitance is calibrated.. And then they still lose 3 mins a month.
