Hi, im working on a data logger project which reads temprature in certain times and writes to sd cards... im using pcf8583 as rtc and let's say i want to trigger alarm every 2 min. and write it to sd card. my problem is my english not good enough to understand what datasheet says... I have done reading clock and showing it on lcd but i couldn't figure out how i going to understand if alarm flag is on or off? Short story, i want to get your opinions to keep tracking alarm bit and which bit im gonna use to do so... Sorry for my bad english and thanks..
