Schematics

I’ll get a proper copy of the schematics up on this site shortly.  In the meantime, if you go to my Parallax 2008 Design Contest entry page you’ll find a link for the contest submission documentation (“Full Description and Data(.pdf)”, in the “Downloads:” section near the bottom of the page”), and inside that document you’ll find a copy of the schematics.

Source Code

Coyote-1 O/S

Latest O/S release: Coyote-1 OS 2.01.02.zip

O/S code releases up to 2.01.02 were maintained and posted to the forum here.

Beginning with version 2.01.02 the code is maintained as an SVN (Subversion) repository on Google Code at http://code.google.com/p/coyote1/.

I’ll be releasing the source code for the OpenStomp Workbench application as well, but I haven’t gotten it posted to Google Code yet.
