Fast GPIO access

So this thread is about transferring samples, but I wonder if there is anything in here which might point to a potential solution:

Minimising round-trip latency

So at the end of my post above I do mention that I managed to get that at one point. However, some time in the intervening weeks since then, I have lost the ability to replicate those results, even though I went back to (what I believe is) that exact same configuration. Thanks for the link though, I had looked at your issue before when researching this issue but got distracted by other problems I was having with the Lime and had forgotten I had seen it. I had actually just independently found o…

E.g. some protocol buffering that could be shrunk to reduce latency.
