The MLC receives commands from Rocrail and lights up the correct LEDs for the current signal aspect.<\/p>\n\n\n\n<p>Find more details about the MLC <a href=\"https:\/\/mattzobricks.com\/automation\/mattzolayoutcontroller\">here<\/a>.<\/p>\n\n\n\n<p>To use the MLC with signals is described <a href=\"https:\/\/mattzobricks.com\/automation\/mattzolayoutcontroller\/mattzosignalcontroller\" type=\"page\" id=\"1221\">here<\/a>.<\/p>\n\n\n\n<p>In the <a href=\"https:\/\/mattzobricks.com\/controllers\/firmware\" data-type=\"page\" data-id=\"5633\">firmware<\/a>, there is an example configuration file called &#8220;MLC_conf_Complex_Light_Signals.h&#8221;. This is a configuration files designed for the MLC mega. This is a good starting point for you. Modify the file depending on the features that the variant of your signal has, and the aspects that it should be able to show.<\/p>\n\n\n\n<p>Enjoy!<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>On this page, you find information about: Media I have created a video about light main signals: Deutsche Version: About the signal The signal was designed by Matthias Runte of MattzoBricks in 2026.
