The zip file SOM-9307M.zip contains a simple VS 2005 project which is a quick and dirty IO demo for the SOM-9307M.  The demo alternates turning every other io line into an input or an output.  You should see every other LD1-8 alternating on and off at 0.3 second intervals and if you connect LEDs or an oscilloscope to the other IOs you should see the same behavior. 

    CAUTION: do not run the demo if you have any external circuitry connected to the digital IO lines.

Note that the demo is a command shell program so if any command shells are open on the
SOM-9307M it will take over any one of them that happen to be open if you launch a remote
debugging session from VS 2005.

The file SOM-9307M.msi is the SDK for the SOM-9307M.  Install this before attempting to compile
the project.

The document How_to_Connect_to_Windows_CE_Device_Without_ActiveSync.pdf tells how to establish a VS 2005 remote debugging session via ethernet.
