PIC Power Project Notes
Since 2005, over 100 full kits were sold, and another 100+ sets of PC boards. The firmware was updated in 2007 to include some minor feature enhancements, including RS-232 interface support. The project appeared in the 2008 - 2009 handbooks as well (give or take). Bill @ Kanga has just a couple of kits remaining in his stock.

The V2.0 code supports serial port output of all of the pertinent data. Note a ugly sprintf bug within the present CCS compiler, which explains the even-uglier formatting within the source code. If you don't like the format of the output, I would encourage you to modify it yourself (I'll probably be doing so as well!)
Presently, the serial output is hard-coded for 9600 bps.
More to follow.
