Bonjour,
Je souhaite utiliser un encodeur rotatif avec une plage choisi (de 0 à 200 par ex.) avec des incréments qui peuvent varier. Je suis tombé sur un exemple de la librairie de Matthias Hertel (RotaryEncoder-LimitedRotator) que je souhaiterai upgrader en changeant l'incrément à partir d'une certaine valeur, seulement je n'y arrive pas.
Par exemple je souhaite que ma valeur s'incrémente de 0.1 entre 0 et 10, puis de 0.5 de 10 à 20 puis de 1 de 20 à 200
Avez-vous des solutions à me proposer?
Ci-dessous le code que je souhaite upgrader.

// This example checks the state of the rotary encoder in the loop() function.
// The current position is printed on output when changed.
// In addition to the SimplePollRotator example here the range of the rotator is limited to the range 0 - 16 and only incremental steps of 2 are realized.
// To implement this limit the boundaries are checked and eventually the current position is adjusted.
// The internal (physical) position of the rotary encoder library remains by stepping with the increment 1
// so the the logical position is calculated by applying the ROTARYSTEPS factor.
// Hardware setup:
// Attach a rotary encoder with output pins to A2 and A3.
// The common contact should be attached to ground.
#include <Arduino.h>
#include <RotaryEncoder.h>
// Example for Arduino UNO with input signals on pin 2 and 3
#define PIN_IN1 4
#define PIN_IN2 3
#define ROTARYSTEPS 0.1
#define ROTARYMIN 0
#define ROTARYMAX 200
// Setup a RotaryEncoder with 4 steps per latch for the 2 signal input pins:
// RotaryEncoder encoder(PIN_IN1, PIN_IN2, RotaryEncoder::LatchMode::FOUR3);
// Setup a RotaryEncoder with 2 steps per latch for the 2 signal input pins:
RotaryEncoder encoder(PIN_IN1, PIN_IN2, RotaryEncoder::LatchMode::TWO03);
// Last known rotary position.
float lastPos = -1;
void setup()
{
Serial.begin(115200);
while (! Serial);
Serial.println("LimitedRotator example for the RotaryEncoder library.");
encoder.setPosition(10 / ROTARYSTEPS); // start with the value of 10.
} // setup()
// Read the current position of the encoder and print out when changed.
void loop()
{
encoder.tick();
// get the current physical position and calc the logical position
float newPos = encoder.getPosition() * ROTARYSTEPS;
if (newPos < ROTARYMIN) {
encoder.setPosition(ROTARYMIN / ROTARYSTEPS);
newPos = ROTARYMIN;
} else if (newPos > ROTARYMAX) {
encoder.setPosition(ROTARYMAX / ROTARYSTEPS);
newPos = ROTARYMAX;
} // if
if (lastPos != newPos) {
Serial.print(newPos);
Serial.println();
lastPos = newPos;
} // if
} // loop ()
// The End
D'avance merci 
. Du coup j'essaye de faire avec avec des exemples que je peux trouver par ci par la en essayant de l'adapter à mes besoins
