Ok, Merci.
Si je reste sur l'option Teensy, il faudrait que je regarde dans la bibliothèque NmraDcc quelles sont les instructions qui sont différentes de celle de l'Arduino.
Je pense que cela va concerner principalement les instructions relatives aux interruptions ? et aux modifications des timers (nécessaire pour piloter le pont en H).
Le code suivant semble compiler sans erreur avec le teensy.
#include <NmraDcc.h>
#include <Servo.h>
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
Ci-joint, pour information (en deux envois), NmraDcc.h et NmraDcc.cpp.
