Found a couple MRC G scale 2.5A decoders on Fleabay for. $16ea, will use them during mechanism debugging and run in. But several of the DH126...
Max stalled I have seen is just over 1.2A with a old dc71
I have recently returned to the hobby . I build Bowser and Pennline steam which are heavy lead engines that when running correctly can draw 1 amp...
Ok, so my ibt-2 had 10K gain resistors, popped those off the board and put a single 1k resister from the connecter IS lines to ground, jmri...
According to the datasheet the 1k resister yields 8.5A/V. Time for some maths.....
The IBT2 is cheap and widely available and has switching times well within the needs of DCC. Also running a device capable of 40A+ at 10A and...
It may not affect main programming, but there is a issue where the IBT-2 bridge chips current sense is desighned for a 40A+ range where we are...
Scratch the MAX471/472, they are EOL. Going to look into other chips.
Well I decided to look at the MAX471 & 472 chip which are EOL and no longer being made. I am also noticing large discrepancies in the output of...
I have noticed the current inacuracy also with my ibt-2, jmri shows 25-30% while only drawing 600-800 ma. I believe this may also cause main track...
This is another place where I see Atani's hard work being so valuable, with his web based interface, I expect that shield variables can be stored...
Testing , gathering data, providing DETAILS of problems encountered is VERY valuable.
Just ordered a 200W 200ohm rheostat to create a variable current load capable of up to 10A at 15V. What would be the diagnostic terminal command...
What is your operating and max current target? Also is current sensing done before or after the bridge? I have a theory that if current sense is...
RS485, now there is a protocol I haven't heard in quite a while, I remember using it to network PCs before 10BaseT came out.....
Yes I was just looking at that on github and as I understand it you are using timers to shape the dcc signal. I wonder if another function is...
I wonder if the "noise" is caused by the high speed switching. If I can find my oscilloscope that is currently packed away it would be interesting...
@Keith Ledbetter Here is something I am kicking around for Auto Reverse......
Bravo Larry, bravo..... This is exactly why I was pushing to limit the number of "supported" motor shields to those trully tested and veted......
Hey guys, as I have been working on my own layout and delving into DCC++ and I had an idea...... Since we have access to the logic level DCC...
