Re: Raspberry Pi Servo pHAT
Jason Rausch
Richard, Yes, that is why I added the coaxial style power socket to my board.? I wanted a robust power connection that would also provide enough current for all 16 servos.? As for Steve Todd's work, I have attempted to contact him several times on various forums with no luck.? I am curious about this, as I have not found much information on setting it up and using it.? I have been using JMRI for several years off and on and while I'm no expert, I have a pretty good handle on it.? I mostly run it on a Raspberry Pi in a headless configuration and just RMD into it when I need to. I plan to still make my version of the board available at my website, once I can work out any changes I want to make. Jason Rausch www.ke4nyv.com

NCE USB Interface
Hello, I want to report that NCE tested my USB interface. It was working correctly. One of the cables I was using was defective. Therefore JMRI could not locate NCE interface. I apoligize to all the members who spent time trying to figure out why my JMRI on my computer may have been faulty.

DecoderPro
I have question about programming in DecoderPro. I have a HP laptop Windows 10 and a SPROG II V3 and SPROG power supply connected to a programming track. This system is used for programming only. I don't know when it happened but I was checking a DigiTrax SDHX166D sound decoder. I tried to change CV 60 to another sound file which I was able to do but the columns with the Read, Write were missing the whole section with those columns is blank. The sheets such as sound, basic, motor etc. do not have write sheet and other tabs missing. Any changed that are made can't be written. I decided to upgrade to 14.7.2 test version and the same happens with the upgrade. I don't know when this happened but it could be that a MS upgrade caused this. I have not used the program in a while for programming but have used it to test locomotives without programming. I appreciate any help but advised that I'm not into programming so need instruction on how to proceed.

Re: JMRI Decoder Pro, EasyDCC, and SoundTraxx
Victor, Thanks again for your help, and again for everyone else's!.
I'm going to end this thread for now. We've wandered far from whether it was possible for Decoder Pro to program SoundTraxx decoders through my EasyDCC system. The good news is it should be fine: others are doing it. Today I got my Pi showing JMRI on a monitor, loaded your suggested VNC on my laptop, and got it connected to the Pi! After that, and more reading of Steve's instructions, I managed to load my existing unfinished panel files on the Pi, and it's displaying my LE panel now. Phew! I didn't need to buy a keyboard, nor use my old Netgear router, either.... A few issues remain.The Pi wants Loconet, not CMR/I and complained about all my turnout and sensor designators. I don't yet have it connected to my EasyDCC. I also didn't get my tablet to connect and display the panel, too. But, all told, it's been a pretty good day! Time for dinner, and to let the old 'gray matter" cool down!?? :--) Don Weigt Connecticut |

Supporting turnouts with feedback compatibility
I have a question about compatibility of turnouts with feedback and turnouts that have a second physical device or supporting turnout configured. BUT when I apply feedback to two turnouts and configure them on the panel to be supporting as you find in a crossover, problems start occurring. |

I've also fixed the edit schedules table so that will be saved correctly in the next test release.

Engine Only Responds to Short Address
I do not know if I did something while running my engine on WiThrottle or something happened spontaneously.? My engine will not run on any throttle(UT4 or DT500) when the long 4 digit address is selected. It runs fine if I select the 3 digit address however.? I do I recover my 4 digit address.? 3 digit is 127 the 4 digit address is 7127.
Thanks in advance for your help. Bob |

Re: JMRI Decoder Pro, EasyDCC, and SoundTraxx
¿ªÔÆÌåÓýHi Don, ? Yes, read Steve¡¯s doc.? ? If I remember correctly, if you are able to connect via Wi-Fi then connect to the Raspberry Pi Hotspot and use VNC to connect and configure the Pi as needed. ?

I'm debating whether to borrow the one from our primary computer, or spend the $20 or so to get another wireless keyboard and mouse for it.

Thanks Dan, Yes, closing the window and re-opening does keep the column formatting the same. Sometimes I just keep opening windows using the PanelPro screen instead of using the task bar.

I should also note that column widths and order are not saved for the edit schedule window.? The details for a window are saved by window name, and in the case of edit schedule, the window name includes the name of the schedule.? This would mean that you would have to adjust each one independently, which I found annoying, so I provide with I believe are the best widths and order.

Hi Bob,
If you resize a column it should stay that way unless you open a second window.? For example if you open the Cars window, the window location, and all of the columns get saved when you close the window.? Now if you open it again, it should be exactly the way it was.? Now if you open a second Cars window, that will have the defaults, you can again change it the way you want, and it can be different.? If this isn't they way its working for you, please let us know.

Suggestion for next release
#operationspro
This is a piddly suggestion (isn't it nice we are at the point where we can entertain piddly suggestions?);? when I resize a column in, say, cars or schedules, the column would stay resized unless resized again? Currently if a column is resized it reverts back to its original size when you leave the screen.
Thanks, Bob Burke |

Re: JMRI Decoder Pro, EasyDCC, and SoundTraxx
Hi Don,
I use Steve Todd's image with my EasyDCC system and a PTB 100 connected to my program track.. I also have a Raspberry Pi connected to the EasyDCC.? I access via wired and wireless using the hotspot in Steve's image.? I like this setup very much. Here is the link to RealVNC the remote desktop app (??). Steve's documentation is good and gives the required passwords and everything you should need to get started. Victor? |

Re: Raspberry Pi Servo pHAT
Thanks Paul,
My board should arrive tomorrow so I can start experimenting. I have already prepared my JMRI preferences (running on the RPi) by adding the Raspberry Pi Foundation as a connection, and configured as RPi GPIO. Once set up in preferences, you can add turnouts in the table associated with this connection. My assumption is that you connect each turnout servo to a specific GPIO pin for control. We will see if that works. Looking forward to your script as well ... Richard |
