Sharing data between M4 and M7 on a Giga R1 at high speeds

I'm working on a project to implement an attitude controller for a quadcopter. Loop times are extremely important as you can imagine. I already have tested code for a cascading controller (inner loop does angular rate, outer does attitude) for a…
