-Now some fun. With all pieces checked, assembled and checked again it is time to power up. It is expected that before you began this project you have already gotten the BeagleBoard up and running with either a serial console or gui desktop. I recommend a X11 desktop like is available in [http://www.sakoman.com Sakoman, Inc.] gnome or [http://www.angstrom-distribution.org/demo/beagleboard/ Angstrom] or [http://elinux.org/BeagleBoardUbuntu Ubuntu]. The X console is more responsive to the fast data throughput of the test program I provide though just a simple serial console connection will suffice.

 I used my revC2 BeagleBoard to build the test app locally. I prefer the Geany IDE. By setting up some arguments in the "Build/Set includes and Arguments" drop down this simple program compiles easily.

 '''Summary'''
-    The TinCanTools Trainer board is a very well designed addon for the BeagleBoard.
-It allows quick and easy testing of user hardware design. All the BeagleBoards expansion header is brought out and voltage translated. The I2C is specially handy with both 3.3V and 5V level translation. Interfacing to and testing signals with an ocilloscope, logic analyser or other form of diagnostic equipment is easily done.
+The TinCanTools Trainer board is a very well designed addon for the BeagleBoard.
-    Those that want to do quick experiments with the powerful Atmega328 AVR have it there ready to program and use. With an on board 3.3V and 5V jumper we can work with either voltage level. I have downloaded a sketch (Arduino program), installed it to the Trainer boards Atmega328 and executed it with ease. If a person wants they could layout headers on the Trainer Board to match the Arduino expansion header foot print. Then adding Arduino compatible shields would be simple.

 This is my proposal to the TinCanTools [http://elinux.org/BeagleBoard_Trainer Challenge] "First person to post a "HowTo" for use with the Nintendo Wii NunChuk and Trainer board wins $150 cash".
-What a great way to motivate people. Offer them cash :) I was motivated but had no TinCanTools Trainer board or Wii nunchuk to work with. Ordering the Trainer from TinCanTools was simple and quick. A few days later it was here. I picked up  Wii nunchuk at a local pawn shop and a nunchuk clone at our Kmart store. Each cost me $10 US. Got all the hardware, I already have a BeagleBoard revC2. Lets begin to review the steps I took to implement communication over I2C with the BeagleBoard, Trainer and a wired nunchuk.
