bonjour
je remets un fichier Word en PJ avec l'essentiel
et ci contre son contenu au cas où ( adapter les lignes avec "AT" et "A")
la solution est d'utiliser des noms uniques pour quelques variables dans les scripts Python
une bonne fin de journée

help about SMA29 JMRI Turnout Channels – Direct JMRI to Arduino Communications
Sat, 2019-11-02 16:05 — lucd
• Track and electrical/DCC
• Tools, tips and tricks
Hello Geoff
J read your article « SMA29 JMRI Turnout Channels – Direct JMRI to Arduino Communications - Simple Support for Lots of Data Out From JMRI »
I need help with this communication between JMRI and Arduino
I am living in France and I built a DCC station with DCC++ and JMRI
I built a module to manage turnout without difficulty from your article and the website « locoduino » (arduino Uno / USB port com 9)
I built a second module with relays to manage switches under 16v alternative (arduino Uno / USB port com 4)
this second module also works perfectly from JMRI when it is alone
But, his presence completely blocks the first one who no longer receives anything
I made the requested changes in the script "Python" (cf the two scripts attached)
I reactivated the messages that can be seen in the console (cf the Word)
thank you for your help
a good weekend at all
best regards
luc

Luc, the discussion

Luc,
the discussion at
https://groups.io/g/jmriusers/topic/32577852 may provide some assistance. in short, there may be duplicated variables that mean the second script is referring to a variable already created by the first script.
Sam

La correction proposée sur un exemple de script
Les lignes en « bleue » doivent contenir des noms de variables spécifiques à chaque canal de capteur
J’ai pris AT et T pour l’exemple
