More than a week ago the boards finally arrived:

Then I soldered the parts into it:

I picked one of my Nuvoton development board, cut it to it's parts, and soldered the missing headers, to be able to use it as an ICE programmer/debugger:

Finally, I started to rewrite the controller's program, to the new pin configuration. During this process, I also want to little bit clean up the code.

To test the board is working, I wrote a "Hello World" for it. :-)

The board looks like working so far. The next step would be to finish the conversion/clean up the code.
