Hi All
It's been a while.
In an EPE magazine in Sep 07, there was a diy project (Flexitimer) which said that it has a timing accuracy of better than +/- 0.02%. If I remember correctly, it uses a PIC MCU with a 4MHz crystal.
I plan to have a PIC MCU and an external 4MHz crystal which I would like to do some counting either in 1sec and 0.1sec resolution. How does one calculate timing accuracy and repeatability?
Thks!
