we have made a board (using LPC1788) as a mini-computer which performs controlling and monitoring in our projects. I perform c coding with Keil u-vision for making firmware. two tasks should be done : task 1:we should 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 by default. task 2: the packet of data must be sent using GPRS ( with SIM908 ATcommands) at specific time. sometimes the rtc runs fast during GPRS data transmition. when data transmition completes rtc works properly again. what should I do for solving this problem.
