Re: How do I get a .hex file out of Xpress?
In Project Properties > Configuration > Hardware Tool, you should be able to select "Simulator / Xpress Board". Then, back in the IDE, when you "Make and Program" your project, it will download a HEX file rather than programming anything.
There is no Export HEX option yet, but the above should work. You won't need to use the programming bridge, and can use whatever type of method for programming from then on out.
