Dwarf Boards is a set of boards that can be combined in very flexible way to create the hardware for your project. Dwarf Boards are cheaper and more flexible than evaluation boards, and much easier than building custom hardware.
The documentation is in Adobe PDF format. Reader software can be downloaded from Adobe's website at http://www.adobe.com.

The Jal compiler used for the Dwarf Notes is a modified version of the compiler available from SourceForge. These modifications will be fed back to the SourceForge effort. Both the pre-compiled distribution and the source for of the compiler are available.

The DB016 has on-board hardware for the Zero Pin Loader (ZPL) bootloader for 18Fxxx chips. All information about ZPL is available as archive. Note that the use of the ZPL PC software requires a the installation of a Python interpreter, and on Windows also the Win32All extensions. Both can be obtained from www.python.org.
