solar controller code migration
Saturday, February 19 2011
The beautiful warm weather was gone by this morning; its only trace was continuing runoff from yesterday's thaw and temperatures that had trouble for awhile pushing below freezing. But by this evening temperatures had dropped into the upper teens. Powerful gusts of wind accompanied this change in the weather, and I watched at times to see if one of the White Pines I'd cut through about 15 feet from the ground (using a rope chain saw) had been dislodged from its very tall stump. It never fell, though it seemed to wander around a bit on that stump. It's just a matter of time before it walks its way off. There is nothing connecting the tree to its stump except gravity.
This evening I whipped up a pasta-and-red-sauce-with-tempeh dinner in time for Gretchen's arrival by bus from New York City. (I had to pick her up from Kingston.)
Imagining that integrating all the new features would be difficult, I've been putting off the task of porting the actual code that drives the solar controller to my new controller board. Today, though, I finally knuckled down and did it, comforted by the fact that my only requirement for now is to get the new system working as well as the existing system; I can worry about implementing the new capabilities later. But I ended up getting all of the old code working on the new platform and even getting the LCD display to show all of the information shown by the old LED-and-analog-meter display in beautiful blink-free digital.
