Adafruit_i2cdevice H Library Hot! Download -

// Read the Chip ID register (0xD0) uint8_t chip_id; i2c_dev.readRegister8(0xD0, &chip_id); Serial.print("Chip ID: 0x"); Serial.println(chip_id, HEX); }

If you’ve ever tried to write a driver for a custom I2C sensor (like a barometer, OLED display, or magnetometer), you know the headache of managing Wire.beginTransmission() , Wire.write() , and Wire.endTransmission() over and over again. adafruit_i2cdevice h library download

#include <Wire.h> #include <Adafruit_I2CDevice.h> Adafruit_I2CDevice i2c_dev = Adafruit_I2CDevice(0x77); // Read the Chip ID register (0xD0) uint8_t chip_id; i2c_dev

Adafruit has solved this with their library. It acts as a clean, powerful C++ wrapper for the Arduino Wire library. Serial.print("Chip ID: 0x")

You don't download Adafruit_I2CDevice.h alone. You install Adafruit BusIO via the Library Manager.
