AS5600 magnetic angle encoder con ESP32

Alimentazione 3.3-5 V Bus I2C Indirizzo I2C 0x36 Misura angolo, rotazione

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
VCC	Alimentazione	3V3	Use 3V3 so OUT stays under 3.3 V
OUT	Uscita analogica	D34	Angle as analog voltage (or PWM, if configured). Optional. To an ADC pin (prefer ADC1: GPIO 32 to 39)
GND	Massa	GND
DIR	Non collegato all’ESP32	—	Direction: GND = angle grows clockwise, VCC = counter-clockwise. Never leave floating
SCL	Clock I2C (SCL)	D22
SDA	Dati I2C (SDA)	D21
GPO	Non collegato all’ESP32	—	Programming pin. Leave unconnected

Collegamento consigliato per l’ESP32 DevKit a 30 pin, evitando i pin della flash, di sola lettura e di strapping. BoardPilot lo controlla mentre colleghi.

Codice di partenza (Arduino)

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin(21, 22);  // SDA = GPIO 21, SCL = GPIO 22
  Wire.beginTransmission(0x36);
  bool found = Wire.endTransmission() == 0;
  Serial.println(found ? "AS5600 magnetic angle encoder found at 0x36" : "Not found: check power, GND and SDA/SCL");
}

void loop() {}
