Hi All,

In timer input capture for both rising and falling How shall I check the input transition whether High to Low or Low to High.

Hello

Can't you just poll the port for level? if high then it was a low to hig transition.

Yep René, that's exactly how I would do it.

I can also recommend to check several time the level, to be sure that you don't capture a glitch !!!

If you do only one capture and there's a miserable glitch at the exact capture of the value, your read will be wrong.

Cheers,
