A site for the development of the software for the MERGCBUS project hardware. MERGCBUS is a new universal control system for DC (analogue) and DCC (digital) model railway layouts.

The Model Electronic Railway Group(MERG) is an international, UK based group promoting interest in the application of electronics (including computers) to all aspects of railway modelling. It's website is at http://www.merg.org.uk/

The MERGCBUS mailing list is at http://groups.yahoo.com/group/mergcbus/ You don't have to be a MERG member to join this list, but PCB's and some of the harder to get parts are available to MERG members from the MERG website.

Currently MERGCBUS modules use the Microchip PIC18F2480 series microcontrollers to interface to the model railway layout, and the CAN (Controller Area Network) serial communications network. Code is being written in C.
