Pretty familiar with DCC etc, I decided to try and build a small unit, so it could serve as a portable test and programming track…. Research done I purchased an Arduino and Motor shield etc… Downloaded and installed the latest version of DCC++ (I am new to this software). Connected up and launched JMRI Decoder pro…. So , I can get a throttle and run/test, however I am unable to do any programming etc. I tried rolling back the DCC++ software to previous versions, and some would read decoders, but then test/throttle would not work. Have ended up back on the latest version. Think it might be something stupid I have overlooked with either the DCC++ software or a setting/ jumper on the arduino unit as I am completely new to these. Any ideas from you wonderful fellow modellers would be most welcome please.
