Help with reading loco-decoder #697

Dear DCC-Ex Team!

Thanks for your great initiative with DCC-Ex for Arduinos, that is really great!

I am trying to set up DCC-Ex (for a M�rklin train set), but cannot read out the decoder of my loco (M�rklin Loco with Lokpilot 5 decoder); I have followed the steps for ACK DIAG, where it says to send you the log if that fails with r -1. The baud rate is 115200, and I have 4 green lights on the motor shield; I have performed this step on the prog.-track. (Had also tried to read out the decoder with JMRI and the Web-Throttle, but also without success: "DCC Address Read Failed!"). When I turn on the tracks (with <1>) then the lights of the loco go on (both front and back), and I hear a very faint continuous buzzing. The loco had worked previously (a few months ago), but I cannot verify that it works now, as I do not have another digital control system.

I have pasted the log, and it would be fantastic if you could help in any way!

Thank you SO much in advance!

With very best wishes, Stefan

There was a current draw when the track was turned on. That indicates that something is there.

However normally a decoder does not turn on the loco lights just when getting DCC. That seems wrong but I have no idea if the ESU might be different from other decoders.

< ACK baseline=28/83mA Threshold=44/131mA Duration between 2000us and 20000us >

83mA standby is a little high but understandable if lights on.

< NO-ACK after 148mS max=38/113mA pulse=0uS samples=155 gaps=0 > < NO-ACK after 149mS max=38/113mA pulse=0uS samples=141 gaps=0 > (...)

After that, the decoder just does not answer. Not much more we can do from the CS. As the light is on, I suspect some decoder problem.
