I've looked pretty hard for them. So far I'm not seeing anything published. I get the concept of wanting to sell/control replacements, though I feel it may be to prohibit "after-market" alternatives or additions.

Quoted from Wolfmarsh:Their communication protocol is mostly known now, someone could reasonably sit down at this point and make an after market node board of their own design.
I don't know if there is any payoff to that though.
Is it though? I haven't seen anything out there that gets into detail about the protocol. Even some debate if it was CAN bus vs. RS-485.
Ok, fair enough, but none of the detail is published there (especially the transceiver type). Unless I'm missing it?
Quoted from Wolfmarsh:Yeah, not everything is published in an easy to consume format for a random John Doe to try and make his own, but the details are known to people.
Let me put it another way: MPF uses the Spike's CPU node to control the bus. You connect your controller to the machine's CPU and how that CPU speaks to the node bus elements isn't clear. I was hoping somewhere in the MPF documentation it would talk about HOW the CPU talks to the nodes (i.e. CAN bus or RS-485, though I am pretty sure there are RS-485 transievers on the nodes).
Because I can't find anything, I'm going to have to find out the hard way! If you know any sources of info, please let me know.
