EDU Demo Code: Encoder Interfacing Using Interrupts

Thank you. I'm glad you're making use of the code.

Would we have to use a timer?

Yes, we'll have interrupts on the new FRC controller. The port b interrupts on the EDU-RC directly map to the first six digital inputs on the new controller (i.e., Interrupt 1 = digital I/O 1, interrupt 2 = digital I/O 2,... interrupt 6 = digital I/O 6).
