Rotary encoder - 1 input to 2 interrupts?

Other Hardware Sensors
1

I have an optical rotary encoder connected to an Arduino Uno. From one channel/wire of the ORE I want to get both the rising and falling values separately.

The problem is that the Uno doesn't allow me to attach two interrupts to a single pin.

So I was wondering about connection one ORE channel/wire to two interrupt pins. Then, theoretically, I could listen for rising on one pin and falling on the other?

will this have some sort of adverse electronic effect? Or is this a perfectly normal thing to do?

If you trigger an external interrupt with CHANGE, you can read the state of the pin in the ISR and determine if it is now high or low which will tell you if it was a rising or falling change. It is the same with pin change interrupts.

Perhaps you can explain more about what you are trying to do.
