Thanks for the info. It is appreciated.
If we want to build a detector from scratch for automatically detecting the state of an O27 switch track, and use only connections to the ground terminal and one of the other three terminals, how would we do it, in a way that would be robust and a simple as possible? This is the question.
Thanks again.
I just reread this post and realize I missed the part about building a detector from scratch. Do you mean not using the STM2 and instead building your own detector to interface to the LCS? That's entirely possible, but not so advisable since all the work has already been done for only about $90. I can however see the interest in how it was done...study the coding of the processor in the STM2, etc. But I don't have any specific knowledge as to building one. There are some forum folks however who would, and if you could create a passion in one of them to undertake the subject, the project might be realizable even though the time invested would far surpass the value of purchasing one.
One thing though is someone mentioned a block detector. That might be a welcome addition to the LCS family for some. Similar technology.
