When the DCC signal is generated within interrupt handling code within the Command Station, the accuracy of the signal cannot be maintained to such a high accuracy. Below, we can see that the pulse length varies over a range of around 14us. ...
and the command station notifies the feedback decoders if it has detected such parity error. For more information on the RS-bus see theder-moba website(in German) andhttps://sites.google.com/site/dcctrains/rs-bus-feed. To understand the design decisions behind, and implementation of this ...
