I am writing a sketch to place DCC electrical signals on the track to control a train with a Bachmann decoder. I am not using a commercially made controller, just an Arduino Uno. Using Arduino I have constructed, what to me, is a packet consisting of a preamble, address, control byte, and XOR check. But still the train does not move in DCC mode. Has a member tried this and is there something else that needs to be done for it to work? The packet I am sending is shown in the attached pdf.
The train does move but in DC mode, when I change parameters in the packet like address or direction,..., the train still only moves forward. So I assume my packet is not being decoded by the decoder. I am working with a member of Arduino.cc on this but am unable to get the sketch to work.
