Slicekit Chain

[TSC]

It's possible to chain two SliceKit core boards together and get something similar to a XS1-G4 (I assume you mean this, a four tile package).

The link between the two packages will be slower than the G4 I think.

It would require a new .xn file to describe the available tiles and links. I'm doing the same thing so I'll post my .xn file once I've verified that it works.

See the xTIMEcomposer User Guide.

Your projects would probably have been using the SLICEKIT-L2.xn file.

Here is the .xn file I just wrote for a master and slave SliceKit setup.
