MobaLedLib

Arduino library for controlling LEDs and other components on a model railway.

New in release 3.2.1: LED simulator, Selectrix support for ESP32, bugfixes

Excel user interface to configure the LEDs without programming at all improved by the engagement of Pattern Configurator and Program Generator!

To start the excel program press the Win+r key together and copy the following line into the "Run" dialog and press enter: %USERPROFILE%\Documents\Arduino\libraries\Mobaledlib\extras\Prog_Generator_MobaLedLib.xlsm

The use of RGB LEDs offers fascinating possibilities for lighting a model railway:

  • Infinite number of lighting effects - Brightness and color of each LED can be set individually and dynamically
  • Easiest cabling - The objects (houses, traffic lights, ...) are simply plugged into a multiple socket
  • Extremely affordable - 100 LEDs for the price of three "normal" lights
  • Up to 256 RGB LEDs (768 channels) can be controlled by an Arduino
  • Up to 16384 RGB LEDs (49152 channels) can be controlled by an ESP32
  • Controlling other components is just as easy
    • Sound modules
    • Servo and stepper motors
    • Charlieplexing light signals
    • Power devices
  • Additional module to read 80 and more switches with 10 signal wires
  • Stand-alone operation or networked with other components possible

The lighting and some additional functions are controlled via the WS2812 / WS2811 chips. For this, only a single signal is required which is forwarded from one chip to the next. This makes the wiring extremely easy.

A lot of examples show the usage of the library. They could be use as startup for own programs.

A huge wiki describes the complete MobaLedLib in detail: https://wiki.mobaledlib.de/doku.php
This library is used and supported by a big community, see https://www.stummiforum.de/viewtopic.php?f=7&t=165060. All software and hardware parts are free of license and available for download.

Several videos demonstrate the possibilities of the library. You will find a lot of articles when searching for MobaLedLib in the internet.

ATTENTION: Always use the actual Arduino IDE (Old versions 1.6.x and below don't support the directory structure used in the library examples)

Ver.: 2.1.1 14.11.20:

  • Removed the old Debug functions to simulate DDC commands TEST_PUSH_BUTTONS(), TEST_TOGGLE_BUTTONS() and TEST_BUTTONS_INCH()
  • Experimental support for ESP32 added

Ver.: 2.1.0 02.11.20:

  • 8% additional configuration memory by changing the reserved size of the fast bootloader from 2K to 512 byte
  • Corrected the support for 64 time entries in the pattern_Configurator. Unfortunately the prior changes have been made in a wrong worksheet and not in the Main sheet => They have been lost when the release version was build ;-(
  • Corrected the importing of data from old Prog_Generator
  • Define at least 20 LEDs to be able to test them with the color test program
  • Disabling the Event which is called when Enter is pressed when the workbook is closed. Hopefully this solves the problem that the Pattern_Config is opened sometimes unintentionally
  • Prevent crash if a wrong formula is entered like "-Test"
  • Updating the arduino type in the "Options" dialog if the USB Port detection is started
  • Charlie_Buttons and Charlie_Binary control 3 channels (RGB) instead of 2 (GB)
  • Corrected the maximal time for the Blinker function by adding PF_SLOW
  • Disable the mouse scroll function for Office <= 2007 because here excel generates a crash

Ver.: 2.0.0 18.10.20:

  • Support for the new buffer gate on mainboard version 1.7 added

Ver.: 1.9.6 K 16.10.20:

  • Don't gray out the other rooms in the House/Gaslight dialog. Instead the important buttons use bold font

    • Corrected the "Dialog" Button. The "Type selection" dialog was called twice in DCC mode.
  • Disabled the "ENABLE_CRITICAL_EVENTS_WB" to hopefully get rid of the crash which is generated if lines are deleted in the Pattern_Configurator. By disabling this events the LED numbers are not updated if lines ade hidden or shown again.
  • Corrected the NEON_DEF2D entry. Channel 1 was used instead of channel 2. This caused the occupation of a new RGB channel if NEON_DEF1D and NEON_DEF2D was used in a sequence
  • Improve the detection probability in "DetectArduino()". Prior the arduino was not always detected at the first trial.
  • Corrected the error detection for the ATtiny upload

  • Improved the "Mainboard_Hardware_Test.MLL_pgf". Now the mainboard could be tested without the PushButton4017 board.

Ver.: 1.9.6 F 07.10.20:

  • Programming of the fast bootloader added
  • Jürgen has added "Update_Start_LedNr" to the end of Read_PGF_from_String_V1_0() because other wise NUM_LEDS is 0

  • Added macro "WeldingCont()" which continuously flickers while the input is active.
  • Don't use the Heartbeat LED at PIN A3 if the CAN bus is used AND the SwitchB or SwitchC is used.
  • Generate an error message if Mainboard_LED(4..) is used together with SwitchB or SwitchC.
  • Created an example file to test the MobaLedLib main board: "Mainboard_Hardware_Test.MLL_pgf" This file is stored in the directory "Prog_Generator_Examples" which is copied to the library destination at startup.
