Gleisbox-only operation (without MS2/CS2/CS3) - Testers wanted
 Joined: 22/01/2025(UTC) Posts: 53 Location: Setubal, Palmela

Dear All - Inspired by work by the Locoduino group ( this project, in particular), I developed a low-cost WiFi hub based on the Raspberry Pi Pico to route CS2 protocol packets between a controller and a 60116 Gleisbox. (It also has a limited number of feedback channels to detect track occupancy.) I've tested it with Rocrail and JMRI but do not have means to try with other controller software. If anybody has time and/or interest in testing and providing feedback, I'd be grateful. Project description is here on Github. Osoraku Edited by user 30 April 2025 11:57:43(UTC)
| Reason: Tested now with JMRI; mention feedback too.

Dear Gopal - As to Raspberry Pi Pico vs ESP32, it makes no odds (except that the expansion board is for the RPP). The main advantage of this project over the Locoduino one is that you don't have to buy components and build the board yourself - once you get the expansion board, you're good to go: plug in the processor and it has all the necessary connections already built onto it. That reduces the overall cost. Happy to help when you get the parts. Osoraku

Gopal Dear Gopal - Ooof - I'm pretty sure it could be made to work, but you'd need to have headers (20 pin female sockets on each side of that board) to plug the RPP into it. That rather thwarts the low-cost/easy setup character of the project: there would be a lot of soldering to do to install the headers. Any other options available? (I thought that in the US they had everything electronic, and cheap!) Osoraku

PS - The silkscreen info on my board indicates that it was manufactured in Germany. Hence, an EU supplier might be a good choice. I found a half-dozen non-Amazon EU suppliers on the web. With the caveat that it should work (same CAN chip used, but different pin assignments), in N. America, the Waveshare Pico-CAN-B board seems to be a substitute and costs 17-25 USD. AliExpress also lists some CAN boards with sockets attached for Raspberry Pi Pico like this. Let me know, and we can collaborate; perhaps I can find a similar board locally.

Looks like CAN can be implemented entirely in software on the RPi Pico W which uses the RP2040 microcontroller. Talk about low-cost! Code is in C, not python, but should be possible to interoperate. Probably beyond my capabilities to get it to work though. Gopal

I went ahead with the ESP32 based project that you mentioned earlier. Reasons: I know Python even less than I know C++, I had a ESP32 at hand, and because the ESP32 has a CAN controller on board, all I needed was transceiver costing about one dollar. No soldering as I am using a plug in breadboard. Not as neat, but fully functional.
Osoraku, thanks for the inspiration and advice.

No layout either, but I do have the two new locos that I bought since I moved house (Flying Scotsman and the Swiss Churchill Railcar), and I have seen some bits of track lying in one of the other boxes. There will be enough for a good test. I can get the track box from my local dealer in a few days - it is in stock there.  |

There is a start set which includes the MS2 controller, track box, power supply and an oval of track. Seemed to be a good buy.

I guess that is the question. Does it have to be a 60116 or will any version of the MS2 trackbox work? |

Dear Adrian - Any Gleisbox that would connect an MS2/CS2/CS3 controller to the track should work. According to this forum link, the 60112, 60113, 60114 and 60116 Gleisboxes work. (They have different max current loads for running HO and 1 gauge locos, but all use the CAN protocol.) Osoraku

I found having the MS2 controller hooked up was useful in testing communication. Of course, it is not strictly necessary as a locomotive on the track will do the trick.

Item number two is here:  The waveboard. I have loaded rocrail onto a linux laptop. I just need the MS2 box, which (hopefully) will be here next week. We had a cyclone and that has messed up (delayed) many things - even for those of us who were not in it's direct path. |

I updated the code to also work with the Waveshare CAN board. You can test the basic functionality of the RPP-CAN interface and the Wifi connection to Rocrail without a Gleisbox using the CAN loopback interface. Osoraku Edited by user 03 May 2025 10:21:26(UTC)

I have ordered a Marklin 29000 set, which has the MS2, the box and enough track for testing. My m-track is in storage until I build the shed - hopefully, later this year. When the shed is built and the layout is ready, I will toss the plastic rubbish out the window. I have also ordered a 10 pin mini din plug as I am a bit nervous about sticking small wires into tiny plug socket pins when there is an 18v pin between the earth and CAN High connection.  I am keen to find a case for the unit - any thoughts? Anyway, I will start the preliminary testing in a couple of days - I just need to do more reading about rocorail and these pico things. I have lots of old PI's model 2 and 3 mainly, but this is the first pico. |

Dear Adrian - The Waveshare board has the same dimensions as the RPP itself, and I think they mate with the USB connector on the RPP and the CAN terminals on the same end. So you need a box to get the wires out at the end. A quick look at offerings on the web turns up the Adafruit Pico W PiCowBell IoT case that seems to have space for your Waveshare board mated to the RPP ... but caveat emptor. Anything that is NOT a metal Faraday cage for your WiFi receiver should serve. Osoraku

The best way to get one of these connectors is to get a spare ms2 cable, that way the connector comes pre-wired. The other end has a JST connector on it, but you could cut that off if you want to connect direct into your hardware. For a box, I would look at using a Hammond enclosure, available from RS or Farnell in a range of sizes and colours, I have used the 1555 box before, which would be about the correct size for your boards.

Anything that is NOT a metal Faraday cage for your WiFi receiver should serve. Osoraku That box looks perfect, but it looks like I need a 3D printer to make one. Sadly, it does not look like anyone sells the case. I will explore this as a long term option as I don't have a 3D printer and I am unlikely to buy one in the near future. The entire assembly measures 52mm x 25mm x 25mm. I guess I will use a cardboard box in the short term, while I mull over the business case for a 3D printer that FD will find believable.  |

I ended up buying this cable on Amazon -> https://www.amazon.com.au/dp/B0C6X In case the link dies one day, I will add the detail here: Traovien Mini-DIN 10-Pin Male to Female Audio Cable for TV Receiver Monitor Projector Audio and Video Receiver etc (Mini 10Pin Male to Female 3.3Ft)  The Hammond cases look good - there is a 65mm x 65mm that would do the job. I can get these from Element 14, but I need to buy other stuff to make the shipping worthwhile. I guess my cardboard box will have to do until I prove that this concept works for me.

Out of bog rolls at the moment - there is a national toilet paper shortage in Australia. It seems that the Australian response to any disaster (flood, COVID, drought, election and earthquake) is to buy as much toilet paper as you can carry. Never mind food or water, but we must have the toilet paper! The latest disaster was the cyclone that attempted to cross the coast at Queensland - shops were emptied through Queensland - Why? Because the logistical geniuses that run the two major grocery chains in Australia thought it was a brilliant idea to warehouse everything in Melbourne and then use trucks that can't cross flooded roads (the toilet paper might get wet) to ship the stuff up the one highway in Queensland.
So will a rolled up banana leaf make a good substitute? |

Dear Adrian -
Edit the program and change POLL = False at the top. Download it again to the RPP and run it like before. You should see slightly different output that says it is running in interrupt mode.

Hello everyone, Are you still interested in RP PI Pico boards with CAN. I've made one with an MCP2515 and can supply the Gerbers and components, but I'll have to dig through my archives. Nice project. Kind regards https://forum.3rails.fr/...passerelle-can-tcp/28552

Dear Christophe -
I'll study your S88 Raspberry Pi pico design - looks very cost effective for 16 feedback channels.
And thanks for the original inspiration.

Oh Yes! I love that s88 design. I was just going to use my LDT HSI-S88-USB to inform Rocrail (and hopefully WinDigiPet), but this looks awesome and I would love to test this too. My test track with a siding comprising two turnouts is already here - so I was hoping to test a solution where each train stops at a "station" for a random time, and the second loco is only "released" after the first loco has moved ahead into a vacant block. This is easy to do in WinDigiPet, and I assume that Rocrail will have the same capability. I also plan to add in the signals - I assume that the pico CAN will manage this. I am STILL waiting for the 10-pin mini-DIN cable - it is stuck at Brisbane Airport somewhere.  |

Not certain if we even have enough to wipe it all out, up, or down anymore.

The cable finally arrived, but FD has a number of social events planned for me. So, I might not be able to finish the testing until next week.  When I finish this project, I will have a good look at the s88 project. |

I have some time this afternoon to progress this one.  I have cut the cable to find that all 10 pins are wired and there is even a copper wire to the outer shield. I have documented the wire colours in case someone else buys the same cable from Amazon for this project. |

Now we connect to the WaveShare board. It is very hard for these old eyes to see the tiny writing, but the WaveShare website has this picture posted.  Looking at the Green Screw block, we see H (CAN HIGH), L (CAN Low) and G (Ground). The next picture shows the three wires connected to the Waveshare board. Green is to G (Ground) Brown is to L (CAN Low) and Orange is to H (CAN High)  Some more testing and then we will plug into the track box and check for any smoke. |

Okay - I need some help here. I am trying to find the two utilities that I need to download. marklin.py and threadsafe.py. I went to this link -> https://github.com/peterhinch/micropython-async to find threadsafe.py, but I can only find: threadsafe_event.py and threadsafe_queue.py in the V3 folder. Where do I find marklin.py? |
