Hi Danny, thank you for giving me a time to think about your problem ! depending of your motor consuption you should get more or less 0.5 V...
So you have the same problem as Quentin : check the cabling of the MAX471 ... If you have a DMM, you can look if there is a voltage change...
@ Danny : Do you get something other than -1 when trying to read the CV1 on the programming track with <R 1 123 123 > at 115200 bauds on the IDE...
Happy to know that it is ok for you. Just to say that I used Rudy sniffer (a V2) on a Pro Mini also without any pin or interrupt change ...
Unless specified, all measurements are made against ground. The 2.5V is the mean value between logical 5V and 0V, so it is direct voltage. If the...
According to my experience : pin6 of the opto and pin 2 of the arduino should be directly connected = no voltage between. pin6 of the opto...
To be more clear, some photos : opto3. you can put a LED directly on an almost exhausted 2032 battery (still 3V). The current is limited by the...
Among the basic tests (sorry if this is too basic): check the return to arduino GND of the opto 5 pin. Check if with a DMM set on alternative...
In this packet, you have a DCC sniffer which allows you to watch the packets sent on the rails via the serial of arduino IDE. (based on the same...
I use Rudy accessory decoders with the same DCC interface as the one you use. https://rudysmodelrailway.wordpress.com/software/ The only (!)...
My reading of this tread : https://forum.arduino.cc/index.php?topic=400519.0 (Sep 18, 2016, 01:44 pm) let me think that this shield is not wired...
Anyway thankyou, I will go on on a trial and error basis ...
Hope it won't take too long ! I see on your video that you use the JMRI WiTrottle. I had a problem with the Firewall of Windows and basicaly I...
You are welcome !
Hi Miguel, nice to have good news. I had also faulty optos, but I wonder if it was not because of hasardous testing, it is very easy to touch two...
Certainly, but a bit smaller ... Difficult to compare with the rockies ! A shot taken this afternoon during snowshoeing (~2h bus from Nice, sorry...
Very please that you solve your issue. You must have the most capacitive (should I say capable) finger of the all forum ! Three photos just to...
By now I am using a V2 version as attached. The timings are sensitive and it is wise to do not modify the sketch. Which one do you use ? Perhaps a...
There are some more details here : http://traindespignes.fr/materiels.html Sorry, it is in french and not possible to have it directly google...
