// 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); }

Adafruit_I2CDevice.h <-- This is the file you wanted! Adafruit_SPIDevice.h Adafruit_BusIO_Register.h Once installed, using the library makes your code incredibly elegant. Here is how you would talk to a BMP280 sensor (address 0x77 ):

Have a tricky I2C device that won't respond? Drop your logic analyzer screenshots in the comments below!

void setup() { Serial.begin(115200); Wire.begin();

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.
