Hi ,

I am beginner in ARM 32 bit LPC1768

I am working on Nmea string .I am receiving string from GPS receiver format is GPZDA,hhmmss.ss,xx,xx,xxxx,xx,xx

I have extracted the data like and date and time and i have stored in separate buffer .

Now i want to synchronize with the RTC .I dont know how to synchronize it .

Please guide me
 

u want to set RTC time as GPS. Then just feed the data to RTC which data received from GPS. that again re initilize the rtc .

I.e I have used following steps
Initialize rtc
Feed the rtc with the value which is extracted from nmea string
Rtc set time
Nvic rtc
