Isn't that a controller not a decoder? And, frankly, the gertbot (https://www.gertbot.com/) has a better hardware spec: four independent 2.5amp channels expandable to sixteen with additional boards. More if you have multiple serial ports available.
Sadly no opto-couplers in my stash (well, really my late father's stash - and he was a lot better than me on electronics), so expecting in a couple of days - breadboard at the ready.Is it possible to use a Pi to read the digital signal that passes along the power line on a DCC (Digital Command Control) Model Train layout.
The gpio on all Pi are 3.3v not 5v and will be damaged if fed 5v so you may need a different optocoupler.Brummbar wrote: ↑Mon Aug 26, 2019 9:23 amI would like to use a Raspberry Pi as a DCC Packet Sniffer (Packet Analyzer). I am new to Raspberry Pi's and would very much appreciate any and all help offered.
I have built an Arduino DCC signal shield before; so, I am familiar with the DCC-to-5v, 6N137 Opto-Coupler circuit; although, not interfacing it to a Raspberry Pi.
This would be a very useful tool for me and others I believe.
There's a couple of ways I can think of to use a Pi as a command station:
