The folders inside need to be moved to the Arduino Sketches/libraries folder on your PC. All other folders go into your Arduino Sketches folder.

RB_RGB_LED_Control

Arduino sketch to control max 6 PWM channels that can control a 12V LED strip via nMOSFET’s. User manual desrcibing the needed hardware and how to configure the software is included.

RB_DCC_Decoder_Function
Arduino sketch for a one address function decoder with max 13 outputs, controlled via the F0 – F12 buttons on your Command Station or handheld controller. More info on this post. Configuration is very straightforward:

int decoderAddress = 1830; // This is the decoder address, change into the number you want.
#define F0_pin 13 // Define the output pin for every Function number in use. 13 has on board LED.
#define F1_pin 0 // Available pin numbers: 3-19
#define F2_pin 0

#define F12_pin 0

RB_DCC_Decoder_Function_ATtiny
ATtiny sketch for a one address function decoder with max 5 outputs, controlled via the F0 – F12 buttons on your Command Station or handheld controller. More info, see above.

RB_DCC_Decoder_Accessory
Arduino sketch for DCC control of accessories. More info is available here. Configuration per output:

accessory[0].address = 1; // DCC address
accessory[0].mode = 1; // Continuous: HIGH until DCC switches the address off again
accessory[0].outputPin = 10; // Arduino pin to which this function is connected

accessory[1].address = 2;
accessory[1].mode = 2; // Oneshot: HIGH for ontime ms, then LOW and stays LOW.
accessory[1].outputPin = 11;
accessory[1].ontime = 1000;

accessory[3].address = 3;
accessory[3].mode = 3; // Flasher: HIGH for ontime ms, LOW for offtime ms, repeats till DCC off
accessory[3].outputPin = 12;
accessory[3].outputPin2 = 13; // Flasher can use 2 outputs, they will flash  on/off alternatively
accessory[3].ontime = 500;
accessory[3].offtime = 1000;

RB_DCC_Decoder_Accessory_ATtiny
ATtiny sketch for DCC control of accessories. Configuration is identical to the Arduino version above.
See this post for more info on installation of drives and ATtiny support for the Arduino IDE.

RB_DCC_Decoder_Servo
Arduino sketch for DCC control of servos. Click here for a list of posts on the servo decoder.
Configuration per servo:
servos[0].address = 1; // DCC address for this accessory
servos[0].outputPin = 13; // Arduino pin number for additional accessory output
servos[0].servo.attach(3); //Arduino pin number where servo is connected to
servos[0].offangle = 68; //Angle for DCC=off
servos[0].onangle = 126; //Angle for DCC=on

RB_DCC_Decoder_Servo_Tune_v3.0
Very basic sketch that I use to tune the servo’s min and max angles to switch a turnout. The workings are explained inside the software. Here are a few video’s. Min / Max values are displayed on screen and then need to be manually configured in the DCC_Servo sketch.

RB_DCC_Decoder_Solenoid
Version of the accessory decoder sketch that can be used to switch turnouts that use two coils for switching. Some additional hardware is needed to power the coils, the Arduino outputs do not deliver enough current for that. Configuration:
accessory[0].address = 1; // DCC address for this accessory
accessory[0].durationMilli = 250; //Duration of pulse in ms
accessory[0].outputPin = 12; //solenoid 1 connection
accessory[0].outputPin2 = 13; // solenoid 2 connection

RB_DCC_Decoder_Sound
Arduino sketch on DCC control of playing sounds. For use with the Sound Software that also is included in the download. This version only plays sounds, has no accessory or servo functions, just to make it simple to use. More info here.

RB_DCC_Decoder_Accessory_Servo_Sound_Delay
Arduino sketch that combines ‘all in one’ control of accessories and servo’s and can play sounds using the additional PC sound software. There’s also a delay function, that makes it possible to delay an output. Useful for instance with a railway crossing: first the 2 lights start blinking (2 output flasher function) and the ding-ding sound starts to play, then some time later the servo moves the beams down.
More info here.

Sound_Software (For MS Windows PC’s only)
Software to install on the PC that works together with the Arduino DCC_Decoder_Sound sketch to play sounds, triggered by DCC.

Sounds
Some sample sounds for use with the DCC_Decoder_Sound and the Sound Software.

DCCSound_User_Manual.doc
Detailed description how to install and to use the Sound Software and the DCC_Decoder_Sound.

RB_S88
Arduino sketch for connection of track sensors to an S88 bus and transmit their data to a command station or PC.
See this post for more info

Arduino used as a 16-sensor S88 detector board (September 2014)

ArduinoUnoSmd I’d like to see if an Arduino can be used as an S88 16x detector board. Why? Well … for one it is just a fun challenge to see if we can get that to work. And next, more interesting, an S88 board sets you back some €40,- … an Arduino just some €6,- !

s88-timingThe S88 interface is a shift register with the timing diagram as shown in the image (info from this website). The ECoS sends out the “PS” and ‘Clock’ signals and reads the data line. I did some measurements on the ECoS. It sends out 512 clock pulses between the PS signals, which means it always reads the maximum of 32×16 detector inputs. With that knowledge I started work on the Arduino hardware and software.

Software:
The Arduino code can be downloaded here: Arduino s88 interface sketch.

The main loop scans all 16 inputs and stores the state in a 16 bit integer called ‘sensors’. Upon receipt of the PS pulse interrupt-1 is triggered, in which ‘servos’ is copied into an integer called ‘data’, after which ‘servos’ is reset to zero. Every ‘Clock’ pulse triggers Interrupt-0, which sequentially sends out the 16 bits from ‘data’ to the ‘dataOut’ pin, using a modulo 16 counter. After sending each bit it reads the data-in, to which the data-out of the next Arduino in the chain is connected. This way all sensors up to max 512 are sent to the Command Station.

Connections:
s88-connectorThe wiring between ECoS and Arduino, looking at the S88 connector, from left to right:
S88 pin – Arduino pin
1 data – 13 (dataOut and LED indicator)
2 GND – GND
3 Clock – 2 ( =interrupt 0)
4 PS – 3 (=interrupt 1)
5 Reset – not used
6 Vcc – 5V
not conn – 12 (dataIn)

Arduino pin 12 is used for ‘data-in’. If more than one Arduino is used, they can be ‘chained’ by connecting the data-out pin 13 of the next Arduino to the data-in pin 12 of the previous Arduino. The first one in the chain has data out pin 13 connected to S88.

For the sensors anything can be used that pulls an Arduino input to GND, like a reed switch or an optical detector. I wanted to try the TRCT5000. See the hardware page for details. However … I changed to using reed switches and little magnets under the rolling stock. See this blog post for a video on that. The reason is that the IR sensors are too sensitive to surrounding light.

Videos:
See this blog post for a video that shows the Arduino S88 board in action, initially with just one Arduino and max 16 inputs.

And see this blog post for a video that shows the final version of the software, with miltiple Arduino’s in ‘chain’.

ECoS screen on PC / tablet / smartphone via a VNC client

(Sep 2014) ECoS firmware 4 has a VNC server built in, which makes it possible to not only show the ECoS screen on your PC or tablet, but also to operate it! A very nice feature.

One could use the Internet browser and connect to the ECoS IP address. To get VNC to work Java Runtime Edition (JRE) needs to be installed and some Java security settings need to be modified. It’s all in the video mentione below.

In stead of using the web browser, the way I prefer is to use a VNC client on the PC, simply because it looks better. RealVNC has a viewer that has a small footprint. It does not even need an insall, just create a shortcut to the file and run it. Works very nice, with scalable window and some other options..

VNC clients are also available (for free) for tablets and smart phones. On the iPad I tried several. The one I liked best is the Mocha VNC Lite viewer.

See this post for a video on the connection and the use of the VNC server / client.

Connect ECoS to JMRI

(Aug 2014) See this blog post.

Connect ECoS to PaHaSoft Koploper

(Aug 2014) See this blog post.

Connect ECoS to Rocrail

(Aug 2014) See this blog post.

Software I use:

(Aug 2014) For model rail layout CAD: SCARM. It’s free and it’s easy to use.

For model railway simulation: Railroad-X , or actually I use the German version Eisenbahn-X. It’s the best model railway simulator I know, although opinions always differ of course.

For railraod control I intend to try out:
Traincontroller This is the software I currently use for layout control (Gold version). Many video’s are available on this blog on its use.
Rocrail
Koploper (a Dutch program, no English translation)
JMRI (Java Model Railroad Interface)
iTrain

All are free software (iTrain is free with limitations, 3 types of licences are available fom €79,- onwards)

  1. Hello Rudy,

    Thanks for all Arduino projects again! I have an issue about how can create a DCC Decoder Function with sound effects, using a little mp3 player ( DF Player mini mp3). Unfortunatelly to comunicate from Arduino to DFPlayer I need to use serial comunication ( SoftwareSerial.h ), but these libraries are in conflict with the DCC libraries ( DCC_Decoder.h ) and dosn’t work! I seen your RB_DDC_Decoder_Sound, but I want create a Decoder Sound function without PC!
    Did you just have same issue? When you have time, please try to help me….. 😉

  2. Hi Rudy,
    I have watched your YouTube footage on the Arduino amongst many other videos with great interest – they are great, however before I embark on purchasing any hardware I wondered if you would be kind enough to suggest the best solution to my conundrum.
    I am in the process of restoring a signal box panel that came out of a signal box in 1986. It has 25 blocks and each block is illuminated by 2 x 12vDC 0.1A light bulbs in parallel. I have connected these to a bank of solid state relays that require a voltage between 3.3 and 5vDC 160mA. I am using a Digikeijs DR5000 Command Station with DR5088RC feedback detectors as I wish to show upto four loco ID’s per block that the DR5088RC captures from RailCom and transmit it back through loconet. As for the computer software, I am currently undecided on whether to use iTrains, Train Controller or Rocrail. I have tried multiple block occupancy with iTrains and it works fine, but I feel that the iTrains software is not as well endowed with functionality as the Train Controller software; have you tried multiple loco occupancy with these other software packages? from what I can gather it will be the computer software that will trigger the signal for the panel blocks to illuminate, possibly via an Arduino, or could the code be written in DrScript on the DR5000 that can trigger the panel block lights? I am open to your suggestions.
    Kindest Regards and thank you for being such an ambassador to our hobby.

    • I have only done multiple locs in a block with TC but only with 2 locs. You need 4, I have no experience with that. My guess is that as long as you have enough detectors per block to detect every train it could work. The best advice I can give is to download TC and try it.

      Yes, the PC software can be used to switch the relays, via a DCC decoder, for which I would use DCCNext (www.arcomora.com) which set you back just €7,50 for 16 DCC controlled outputs.

  3. Hallo Rudy,
    i have S88 arduino nano board with digikeijs DR5000 and your S88 Software.
    The signal comes correct, when I grounded an input.
    The problem is, the neighbor bits are jitter!.
    Connected is over RJ45 cat 5.
    What can I do? Please help me.

    • What helped with me to suppress flickering is to connect all unused inputs to GND and particularly pin 12 of the final Arduino in the chain. It’s the input where the next Arduino should be connected to, but if it is the final in the chain there is no next. What might also help is to tune the delay timing that is somewhere in the code.
