DS1307 does not have dedicated alarm registers and mechanism, but has user data space 56 bytes. Store alarm time inside(battery backup-ed) ,
compare this time with default time in Your software. Absolutely . And if you need a chip with Alarm function inbuilt then you may use PCF8583 or the PCF8563 . AP PS : I have found PCF8583 more accurate than th Dallas stuff with similar PCB layouts . |
