How to create a time triggering function

[bugzbunny]

Hi... I'm working on a project which involves a data logging system. Currently I'm able to extract the data (voltage, current and power factor) and convert it into text file. However, I would like to simulate a time triggering fuction such that the system will start to activate when the preset time sychronizes with the computer clock. May i know how i go about achieving that?? Thank you.

Hi Kenny,

I assume that you kind of want to just compare the system time to a preset time. This can be done by polling the system time at a certain interval. The result of the comparator can then be used to trigger something. This can easily be accomplish as shown below.
