Lyxmotion Encoders

Hi,

I'm running some tests with a encoder from Lynxmotion.

http://www.robotshop.com/eu/en/lynxmotion-qme-01-quadrature-encoder.html

I'm new at this so I want to start off simple by using only channel A.
The specs are

• Cycles per revolution: 100
• Quadrature counts per revolution: 400
• Frequency: 30kHz

How many (RISING) signals do I need to count for one complete wheel rotation?

That would be 100.
