// 2011-06-26 Migrated into Arduino library from OpenDCC codebase
|
|
// 2014 Added getAddr to NmraDcc Geoff Bunza
|
|
// 2015-11-06 Martin Pischky (martin@pischky.de):
|
|
// Experimental Version to support 14 speed steps
|
|
// and new signature of notifyDccSpeed and notifyDccFunc
|
|
// 2017-11-29 Ken West (kgw4449@gmail.com):
|
|
// Added method and callback headers.
