Fast Shutter Control using the XMOS XS1 platform, version 1.0

This is a simple program for the XMOS XS1 platform, originally
intended to control an electrostatic shutter on a scanning
transmission electron microscope.  It's primary purpose is to turn
something (or multiple things) on and off with very deterministic
times, with minimum on/off switching times down to about 200 ns.

To use this code, you'll need an XMOS XS1 device.  The XS1 is the name
of the architecture, and there are several different devices you might
find.  The code was developed on an XC-1A development board, which has
an XS1-G4 chip.

To flash this code to your XMOS device: - Check out the source code
from this repository.  
- Open the XMOS development environment.  
- Click File-> Import...  
- In the General folder, select "Existing projects into workspace" 
- Point the root directory to the folder where you have the source
code.  
- Click OK/Finish - Click Project -> Properties 
- Expand the C/XC build menu, then click settings in its submenu 
- Under the mapper/linker settings, set the target to be the
  proper target for your XMOS device (for me, it was an XC-1A, since
  that's what device I have.)  
- Everything is all set up now, you can flash the fast beam shutter 
  code over as you would any other XMOS program.

Have fun & good luck.
