Hi @FlightRisk, What you should see: At startup register one is loaded with the idle packet. Register one is then continuously sent till you...
In addition to Atani's reply. The specs for the L293D says it is only good up to 600mA. Even more restricting, it gives the usable frequency as...
OK. I uploaded the updated code to my DCC++ unit and found a problem. It no longer read the current and hence no over current or short circuit...
Thanks for the links. Willem
The problem was that I made certain assumptions as to timer 1 register behaviour. Registers OCM1A (Output Compare Match 1A) and OCM1B are double...
Forget about the 328P. I have a suspicion as what is happening. I made a change based on a wild guess. Since I do not have an analyser and I am...
I do not have a scope or logic analyser so I never looked at the result for this, or the original on an UNO. The basic data stream is correct for...
Remember, That schematic is a fully self contained controller with dual motor driver for both main and programming tracks. I am using DCC to...
Attached the promised files. First is the ATtiny 85 DCC++. A few pointers. All code not related to the mobile side has been stripped. Only one...
I presume you are talking about Travis' "tinyDCCpp". Yes, he does not use the same core. I do use the same ATtinyCore as to you. It does not...
I see more "don't use sewing machine oil" warnings than recommendations. It seems the overall consensus is that is not really plastic friendly. My...
Glad you got it working. Enjoy. Willem.
Glad you had some success. That is not quite the behaviour I would have expected. Even with 13V at the tracks the loco should move smoothly....
As Keith said - 15V is fine. Do not, initially at least, change the sense current from 300 - it will trip at about 800mA. If you can turn the...
Thanks for the update. While waiting for your replacement Pololu, your Arduino motor shield giving 13.4V on the rails should be ample to run a HO...
The above pre-empted my next question. (Are you sure you are using the correct decoder address). Does the loco have lights? If so, can you turn...
Thanks. So we can have a settings problem effecting only the Operations track. I think we have cleared that one. The Programming track seems...
I am a total layman when it comes to JMRI. Cannot advise on that. However, from the opening post it seems that reading CVs work. That implies...
Understood. I missed that in your initial post. The station does seem to work, being able to read and write CVs and seeing in-range power on the...
If the "D' command pulses all the output LEDs as expected, and you measure 13.4V AC across the tracks, I would guess that the DCC++ system is...
