Return -1

[Franky1265]

Hi, first thanks for that cool project.
I bought an ardolino uno, a ardolino standard shield, and use jmri.
Within 2 days all woks fine except the programming Read cv
I have 16 volt dc, and i can program any cv. But when i want to read at the programmtrack. The motor ist moving sime milimeter. But i get back -1 no reply. It is mo contact problem as i connected the lok with krokodiles. I used the master ardulino software.
Can anybody give me a hint

Hi, i went on but did not solve the issue.
When i send <R 1 123 123> In the ardolino stetch i also get back -1
And the power at a1 does not change dc or ac. Voltage. The lok is jumping.
I opened the 2 brak bridges and the voltage bridge.
Can now anybody help me please
Regards Frank

Franky, I haven't been following your current project but I built several Uno and Mega DCC++ systems. I've never cut the break point on the back of any of my DC motor shields. Does the project your working on require you to do this.? If not, try a simple test and reconnect the break by either re-soldering or tape wire across the point to close the connection. Leave the VIN point cut or open. Reassemble and test the code as is. Regards, Kevin

Hi Kevin,
My project is just running dcc at HO
I connected the 2 break point again,
Still the same, all works except the reading cv
I tried Lenz silver esu lp 2 and 4 at least the lenz lok is jumping

[Franky1265]

Does anybody know how the voltage at A1 is moving when i resd cv.
Is it measurable wit a normal voltmeter, is it dc or ac,

[Franky1265]

So, i looked a0 there dc is increasing till 1,4 volt . When droving. At a1 i see no milivolt even no flipping with the osziloskop. The parrot is dead. I come back when i changed it

[Franky1265]

Me again, the motorshield was defect. Now it works. And a1 is flippind with a 5 euro multimeter to 0,2 volt dc when i read cvs

Franky, Congratulations, Good Job finding the problem. Enjoy DCC++ Kevin
