It is on my list of things to learn/have one (Orange Crab). I just haven't had a specific use yet. I know they use them for video out/camera for example. One day... so many things to learn/need time.
The orange crab looks nifty. My recommendation is to start very very simple. I'm not sure how this board integrates with the tools with their DFU mode and all that, but hopefully it allows the same quick iteration as JTAG. I think the next time if any you feel like using a microcontroller, try using the FPGA instead.
Thanks. I listen to EmbeddedFM and I always hear about JTAG but have not used one. Interesting thought about subsituting an FPGA for a microcontroller. Guess you would have to know how to use one in order to do something trivial like blink/move a servo.
