Using an Arduino Mega with CMRI For JMRI

Рет қаралды 11,126

Күн бұрын

This video is the first in a series about using C/MRI with JMRI to control lighting and sensors on your model railroad. I created this as there are several videos that show that their code works, that did not fully vet the process. With help from my friend Dr. Geoff Bunza and four volunteers on the JMRI groups.io, I have created this sensor and output sketch that works every time.
This can be used for detection, signaling, or used to animate projects on your model railroad.

Only just stumbled on Creaky Chair Models while trying to solve problems with CMRI, Laurance's explanation was really helpful and was looking forward to his other video's he was proposing Was upset to find out he had passed away, passing on my condolences to family, friends. A loss to the model railway / railroad community. R.I.P.

Lawrence, thanks so much as I am doing my block detection and signaling with Cmri , jmri and Arduino mega’s as nodes as we speak, my DCC ++ has been working beautiful for years so finding your channel is awesome, Dave…

Thank you so much for your kind words. I am a bit behind on releasing my next video as life happened a bit. Maybe this upcoming weekend.

This is a great video! Thanks so much for sharing. I love automation and code and since I’m just starting my Ho layout this is going to take it to a whole new level. I know it takes time to create this content and it’s much appreciated. I also enjoy hearing you on the Crossing Gate podcast. 👍🏻👍🏻

Thank you, Lawrence, this video explains step-by-step information for novices such as me. I enjoyed every minute of setting this up. This is the first step in building a new layout in oo gauge. I shall look at your other videos to see what I can add next.

Thanks for sharing your experience, I find this C / MRI + JMRI solution for the management of sensors and lights very interesting. I had seen another video with some examples of the code and I was able to get my DCC, Sensors and some lights to work. I kept looking for other videos with no luck, until today. I hope to see your future videos on this topic, and learn a little more about its use and configuration. Thanks again for sharing your experience.

Thank you this was fun to get working and solve the riddle of the resetting Arduino Mega!

This is exactly what I was looking for. I am rebuilding my layout and am planning half of it to be fully automated for those days when I just want to relax and let trains run. I am ordering these items so I can get started in the next few days. This weekend is my first track laying day!

@LawrenceEggering Жыл бұрын

Thanks for the kind words. I use this on my layout all the time with excellent results! The first day of track laying is always huge.

Thank you very much for this excellent video and for the code. With the benefit of your detailed explanations and experience, I have managed to get by Mega/CMRI/JMRI setup working well. Below, shaung75 mentioned that credit for the code should go to Little Wicket Railway. Rob, from that channel, inspired me to have a go but I could not get his code to work for me. I am delighted that yours worked first time. I am next going to experiment with the addition of PCA9685 servo driver boards.

Thank you for the kind words. I also had trouble with his explanation. It got me motivated to make this work. I have a friend who is getting ready to have 90+ servos on his layout that will be using the beginnings of this code so it was time well spent.

Would you mind sharing the code please.i can't get robs project to work also.thanks

Good morning! Why don't you use multi-item creation when adding sensors, lights or other things to JMRI tables. I also had another question about your videos. Create a C/MRI connection, create nodes, create items in tables. I realized that you save properties and exit and enter JMRI. Did you notice any extra need to "give time" for JMRI to notice all these creations?

When I try to upload the sketch I keep getting "Invalid Library...\CMRI: no headers files (.h)... I've tried from scratch on three different computers and two different Uno's.

Be sure you have added the C/MRI library to the libraries folder for Arduino. For PC it is usually located in documents/Arduino/libraries.

Not really, he did inspire me but his system does not work without extensive modification. Tom’s Trains and Things and the developer of the libraries had it out first.

is there anyone here that would like to share the code ? R.I.P. Lawerence

Official Arduino Mega recommended input voltage on DC power jack is 7 - 12V, so all this talk about required regulated 5V power supply makes no sense whatsoever...
