The additional line of code after the clear overflow flag is to test the timer whether the timing is accurate or not. Let's say of ms can't be seen, but at least for the seconds can be seen accurately right? Previously the coding was to display the final value directly on the LCD after Stop button is pressed. Conclusion is, I wonder the 1ms interval can be achieved or not.
From my codes structure, is achieving 1ms interval timing possible? Is there any modification need to be carried out besides displaying final timing value on LCD, in order to achieve 1ms interval timing?
