But no matter how you place, the thing to watch for is the character change in the team members. The trophies are only important for a few hours. The character that is built will last a lifetime. - BrothersKeepers [more]

It does indeed measure the pulse width. Are there any specs on the accuracy?

It can either measure the high pulse (rising edge to falling edge) or the low pulse (falling edge to rising edge). The Digital Module has a resolution of 6.525us. The counter IP has a resolution of 2us.
