I'm working with the STM32F3 Discovery board.  I'm wondering if it is possible to use a timer in encoder interface mode with the signals coming in on Channels 1 and 4.  Do you have to use channels 1 and 2?  Does the Timer just measure the difference between the two channels that are initialized?  Thanks for the help in advance!

    I've solved my problem, even if I'm not too sure of the answer to this question.  I don't think that it's possible from what I read online, but I figured out a way to use channels 1 and 2 on a different bus for my implementation.

    Typically it pairs TI1 and TI2 for the encoder, I'm not sure you can use it with other pairings like 3/4.
