I've been using my new ATJTAGice-MK2, trying to look at the outputs of a hand operated quadrature encoder. I find that when I'm in debug with the JTAGice-MK2 in AVRStudio, things go really slow.
When I rotate the encoder, it's about a full second before the accumulator LEDs update on the STK600. When I take the JTAGice-MK2 off line, rotating the encoder results in instantaneous updates of the accumulator LEDs on the STK600.
Is it that I do not have the JTAGice-MK2 set up properly, or is this just the way it is with the JTAGice-MK2?
If this is the way it is with the JTAGice-MK2, I'm thinking that a logic analyzer might be more useful to me.
