VL53L5CX 8x8 multizone time-of-flight con ESP32

Alimentazione 3.3 V Bus I2C Indirizzo I2C 0x29 Misura distanza

Pin e collegamento all’ESP32

Pin	Ruolo	Pin ESP32	Note
INT	Interrupt	D35	Data ready, optional. SATEL-style order; other boards differ
I2C_RST	Non collegato all’ESP32	—	I2C reset, active HIGH. Tie to GND
SDA	Dati I2C (SDA)	D21
SCL	Clock I2C (SCL)	D22
LPN	Ingresso (lo pilota l’ESP32)	D25	Low-power enable: HIGH to talk over I2C. Can be tied to IOVDD
PWREN	Non collegato all’ESP32	—	Enables the on-board regulator. Tie to IOVDD
AVDD	Alimentazione	3V3	Use 3V3
IOVDD	Alimentazione	3V3	Use 3V3
GND	Massa	GND

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(0x29);
  bool found = Wire.endTransmission() == 0;
  Serial.println(found ? "VL53L5CX 8x8 multizone time-of-flight found at 0x29" : "Not found: check power, GND and SDA/SCL");
}

void loop() {}
