Not identifying, I think it's dead
Here's the scoop
I've been using BS2s for years. I have a PC board I use for my projects. It is a known good board.
Now I plug in a BS2sx and it won't identify. Looked at the board to see if bad solder etc, nope
tried a different known good Pc board [noparse][[/noparse]with 7805 regulator rather than 78L05 which gets hot on the sx], no indentify. I would try a different stamp but it's all I have right now.
Same computer, same usb to serial cable, same stamp software. Everything worked before. I think it must be DOA

Considering it's 15 degrees F outside, snowing, and predicted to get colder yet, I think I'll leave that stamp alone.
The outdoor furnace is a Taylor stove. It is a big wood burner with a 450 gallon water jacket. It heats the water to 180F . The hot water is circulated thru underground pipes to radiators in the house. There is also a heat exchanger in the water jacket that is used to heat hot water.
What the stamp does is:
1, run the air blower that fans the fire when the water temperature is below 180F
2, run the circulating pump for the radiators whenever the house temperature is below 66F
3, run the hot water circulating pump when the hot water heater is below 130F
4, display the status of the system on an LCD screen in my bedroom so I can see what's going on
5, display the outdoor temperature and time of day
There are other functions in the code to handle situations like when the fire goes out [noparse][[/noparse]rarely] so as to make the best use of the stored heat in the water tank
The system lives in my basement so it is not exposed to the elements
It was built from stuff hanging around my house early last winter so some of the circuitry is a bit unorthodox
