Hi Barry, I have been playing with DCC++ Command Station directly over Serial line, typing in commands and reading responses using simple...
I believe you don't need flow control with Mega's USB. Take care to properly input each and every symbol of commands you are sending. Remember,...
In short, you can access CVs either on Main track or on Prog track using "w" or "W" command. Check this out:...
For the record, this was my old setup: [ATTACH]
The project in KiCad format is available here - https://github.com/timtashpulatov/dcc/tree/master/DCC%2B%2B%20Shield/dccshield
The chips under question have accuracy of about +/-28% worst case, my experience with similar ones was that they can be calibrated to give...
The two current sense resistors on IBT-2 are external 1K surface mount resistors, tricky to desolder but doable. It is not quite clear from the...
I don't think the incorrect percentage reported for the IBT-2 by JMRI has something to do with problems with programming over the main. POM does...
MAX47x are said to have 2% accuracy, and require external current sensing resistor for currents over 3A. I personally would prefer using built-in...
Well, it works upside down :) Posted the results in a separate thread:...
I've got two old locos from PIKO, each running at 0.5A max I think (never was able to register more than that even at full speed), and a Roco...
Thought I'd post this as separate thread. Got my selfmade DCC++ shield up and running, with just a few bloopers. [ATTACH] Turned out the...
Got the PCBs, will assemble and test shortly. [ATTACH]
Found a great article from 2016 by incredible Geoff Bunza on Differential Absolute Position Detector (DAPD):...
Indeed, BTN8982 current sense output is rather sloppy. The application note proposes several methods to enhance tolerance: [ATTACH] I believe...
I'll take a better look at heatsink mounting Keith. Maybe going for through hole parts with screw mounting holes, like TO-220. Could turn out to...
Trusty, Is the DCCpp library free of bug that DCC++ supposedly has when sending 'M' command? Mentioned here:...
These particular parts are not well suited for easy heatsink mounting. Their bottom pads would have to be isolated from common heatsink, or two...
Something like this: [ATTACH] The 6-terminal connector block carries VCC, GND, and two pairs of Main and Prog outputs. Perhaps not enough copper...
Looks interesting. How difficult it would be to add support for yet another motor shield? I'm thinking of hacking one to replace current mess of...
