Hi friends. we have made a board (using LPC1788) as a mini-computer which performs controlling and monitoring in our projects.
we want to show clock time (hour : minute) in top-left corner of display. So we use thread function (using CMSIS thread function) with low priority. thread function gets the rtc and shows it continiously. it works properly but sometimes the time time lag occurs suddenly.
for example 40 minutes difference is seen between displayed time and current time .if I restart the board the displayed time becomes correct (the board has battery). any opinion?
