DigiTrains 2.2 on Play

Several new functions in DigiTrains latest version. It is available now on Google Play.

Release notes:

-Train control screen will return to the same train from the quick-list if you navigate to another window.

-Control your locomotive with volume buttons in train control menu. No need to watch the screen.

-12 new function icon for your locomotives:

-New In-App Product: Loco Sounds: If you do not have sound decoder for a locomotive, with this solution you will be able to play certain sounds on your phone or tablet speaker. More than 25 different sounds, like horns, whistles, door sounds, etc.

-If you use a black Z21, and beside the smartphones you also use Freds to control locomotives, sometimes you need to change the loco address in Freds. If you use DigiTrains you can change address in a Fred from DigiTrains Settings / Dispatch address menu.

-Optimized usage of background pictures to avoid app crash because of out of memory error on certain devices. This error usually happened on Samsung devices, where the Samsung Android OS handles the memory on a different way compared to simple Google Android OS.

-When DigiTrains used with JMRI, there was a bug in showing the locomotive pictures which have a space in their name (Roster ID). This bug has been fixed.

DigiTrains - JMRI quick start videos

I created two videos today to show how easy is to use DigiTrains with JMRI.

 It is also useful for not JMRI users, the main difference is what you select after startup in Connections menu. Of course not JMRI users (Z21, DigiWifi) must add trains, accessories by themself and create routes and layouts as well.

Emergency STOP one locomotive

A new function in DigiTrains 1.9 is the emergency stop of the currently controlled locomotive. That is straightforward if you want to stop your locomotive you will press the normal STOP button on the train control screen. In this case the train will stop as it is defined in its CVs. If this is set to be like in the real world the train may stop on a quite long way. But what if you want to stop it immediately because of an emergency? You may use the Main Emergency STOP button on the top right corner, but this will stop all the trains on your layout. There is a better option now!

In Train Control menu you can LONG-TOUCH the normal STOP button between the + and - buttons. With this the currently driven locomotive will stop immediately, independent from the predefined CV values. This command will not influence the other locomotives on the layout. This functions is available on some throttles like the LENZ LH-100 (press the direction changes button).

Animated video test

I saw a cool animated video yesterday evening, and I got the feeling to make one about DigiTrains. I played with it for 3 hours. Maybe I will do more in the future, since I like these kind of videos. Watch it fullscreen, it is better like that.

DigiWifi 2.0

DigiWifi can be purchased in shops or on www.digitools.hu for 6 month now. It is used by individuals and some clubs as well. We got several feedbacks, and we made some changes based on them.

The new version is called DigiWifi 2.0 and it supports unlimited android device connections. So by purchasing one DigiWifi for the price approximately 260€ you can play with as many android handheld as many you have. So friends, kids from the neighbourhood can come and play on their phones. Knowing that one MultiMaus costs something like 140€, if you do not play alone then it worth to use DigiWifi and DigiTrains.

There are serveral new functions also in DigiTrains 1.7, for example the graphical route control module, called dispatcher.

DigiTrains used by Hungarian Model Railroad Clubs

In spring I played on several exhibitions with one of the Hungarian model railroad clubs called "Tram no. 1 Club". They have a Z21 command station, so we used the Z21 and DigiTrains application in parallel. Some of the visitors could also try it walking around the huge layout with their phone in their hands.

Since the Z21 command station has an XPressNet interface, we are able to connect the DigiWifi to it, just like connecting a MultiMaus. The two smartphone application (DigiTrains and Z21) can work at the same time without any problems, so everyone can decide which one to use. Several club members decided to use DigiTrains, since it has an additional functionality for Hungarian users, and this is the station speaker announcment. With this they can play announcments edited by them, choosing signals, track numbers, train types and so on. I am looking forward to make this module also for other langauges if somebody can provide me sound files and help to do it. If you can, please contact me.

DigiTrains can be downloaded from Google Play

Now the DigiWifi is in stores in Hungary in shops Vasútmodell-centrum and Modell & Hobby. DigiTrains can be downloaded from Google Play.

TEMOFESZT - the first serious test on an exhibition

After 6 month of development we have the first test release of the application, called DigiTrains.

Locomotive library:

Accessories:

Locomotive control:

Furthermore the XPressNet - WiFi adapter is also ready, called DigiWifi. I think it has a nice and professional housing.

DigiTools

In February, 2014 Tamás from Digitools contacted me. He liked the application and we decided to work together. Digitools is a Hungarian company developing and manufacturing electronics for model railroading.

The plans was to enhance the functionality of the app and to change the design a bit using colors of Digitools. Furthermore instead of using the PIC 32 Starter kit we made a more complicated circuit with WiFi module and XPressNet communication. So there is no need to use a WiFi router if you use DigiWifi, it creates its own WiFi network. Also with the XPressNet connector it is compatible with the most command stations already used by modelers.

Command Station

Of course I needed a circuit which communicated with the TrainDcc application running on the android devices and generated the dcc signals for the booster. I used a PIC 32 Starter kit (from Microchip) and I wrote a program which generated the dcc signals based on the commands get from LAN. The router made my LAN connection to wireless and the android devices were connected to it.

Here is a shematic how it worked.

TrainsDcc

TrainsDcc...that's how it started. I decided to write an android application to my Sasmsung Galaxy Ace phone to be able control my modell railroad layout. This happened in autumn, 2012.

This time I was already finished my first dcc decoder and house-made booster. I also made a handheld, similar to a MultiMaus. It was made from a counter machine, actually. To be honest, I did not like to control the layout using the lot of buttons and the small 2 row LCD display. It was hard to switch the turnouts, and control 2-3 locomotives at the same time. It took too much time to change always the addresses of locos and accessories to control them. I also tried a MultiMaus after that, but actually I felt the same. Also the CV programming was quite complicated. So I decided to create to myself an easy-to-use user friendly application to my touchscreen phone.

I did not want to use a PC for that, because a PC is more expensive than a phone, it consumes much more power and usually it is noisy. Also I work on a PC every day, and I do not want to use one when I play. Other thing compared to a PC is that with my phone I can control the layout by moving around it and using the WiFi of my device to communicate with the command station.

So I bought a book about Android and JAVA programming. After 3 month I had the first release of my application with the following functions: locomotive library, locomotive control (throttle) and CV programming. It looked like this:

Locomotive control screen:

I know it is not the most beautiful one, but it worked. Locomotive library (pictures made by the camera of the device from the application):
