Some time ago I was playing with an accessory decoder (can't remember which one of hand) but the address it responded to was plus (or minus) one from that expected. Might be worth giving that a try.

thanks for the tip... i will do some tests with that information and will post the results here. I beleieve that someone may have the same problem...

I think this is probably due to the way the MRC Prodigy handles the accessory addressing. I'm not familiar with this equipment, hopefully someone will come along and explain in detail.

I think this too. I searched on internet somethink about MRC packet format to check if there is some particularity about it, but i didn´t found anything helpfull. Just the NMRA packet format. Anyway, thank you about your considerations. I hope someone can help me with this...

Hi friends! After following this fantastic topic for a long time i decided build my turntable based on original code from Tender. I´m testeing the positioner system and found something strange. On my system, a NCE DCC, it´s working very well. But testing in friend´s layout, which uses a MRC Prodigy Wireless, it don´t work. There is some difference betwen NCE and MRC DCC packet? Someone have or had this problem too?

Thanks for now!

Hi,

 

This may not be a solution for you, but I've seen other people have a trouble trying to drive an LCD display from the same Arduino that they are using to decode/encode the DCC Packets. It's down to the timing frequencies required by the libraries. To combat this, I've seen two Arduino's used, one to decode/encode and one to handle the display.

 

This YouTube video may be of help -

 

Hope it helps.

 

Cheers, Mark.

Hi, Mark...

Thanks for the tip! It helped me see that I'm on the right way!

This is exactly the solution I imagined. I considered using an I2C display, but I'm not sure if the libraries will work well together, and maybe I have the same problem. Just a doubt, the design of your video? If yes, how do you transfer data from one arduino to another? Could you share the code?

Thanks!

Hello Ray, how are you?

 

Very good your project. Thanks for sharing!

I was working on a turntable but it would not, at first, controlled by dcc. Only keyboard and LCD. I'm using an external drive microstep and Arduino Leonardo to generate the STEP and DIR signals. When I saw your project, I decided to test to see if I could incorporate the controler by DCC on my project . But I'm having a problem here ... Leonardo apparently does not recognize the DCC commands. Even the example that comes with the library is not working. The code is not highlighted with the commands.

Do you have any idea what might be happening? 

Could be an incompatibility with the Arduino Leonardo?

 

Could you help me?

Hi guys,

As I mentioned, I'm working on a turntable that would not be controlled via DCC. Still, was testing the library and it wasn´t working , and do not decode the DCC Packet. I decided rewrite the code, part by part and test the modifications, and I think I finally found the problem. I believe that there is a conflict occurring between the DCC Library and the LCD Library. Sometimes the code works for a time and then stops withiout a apparent reason and sometimes does not work (just DCC packet decoding). When it stops working, I delete the commands relating to LCD, recompile the code, and the program restart. I rewrite the lcd commands again and the error recurs. I´m thincking to replace the LCD by i2c seven segments display.Anyone ever had similar problems?
