Teensy 4.x Quadrature Encoder minimal example in PlatformIO/Arduino

This example uses PlatformIO and the Teensy-4.x-Quad-Encoder-Library to implement a hardware quadrature encoder on pins 0 and 1. Remember that the teensy will be destroyed if you use 5V encoder signals. You can only use 3.3V signals!

#include <Arduino.h>
#include <QuadEncoder.h>

QuadEncoder encoder(1, 0, 1, 0);

void setup() {
    Serial.begin(115200);
    encoder.setInitConfig();
    encoder.init();
}

void loop() {
    int32_t position = encoder.read();
    // Compute position in mm and print it
    constexpr float mm_per_count = 0.0012;
    float mm = position * mm_per_count;
    Serial.printf("Position: %+3.4f (count %ld)\r\n", mm, position);
    // Print every 50ms
    delay(50);
}
