How do I find I2C devices on my Raspberry Pi?
Checking that I2C is enabled
- raspi-config in non-interactive mode. as mentioned above, you can read the state of the I2C port with.
- I2C device node. When I2C is enabled on the Raspberry Pi, you will also see a /dev node for it:
- gpio readall.
- lsmod.
- i2cdetect:
- raspi-config in non-interactive mode.
- I2C device node.
- gpio readall.
Can you connect multiple I2C devices Raspberry Pi?
You can connect multiple I2C devices, such ADCs, LCDs, and sensors, to the I2C pins on the Raspberry Pi hardware. Each I2C device on an I2C bus must have a unique address.
Does Raspberry Pi have I2C?
I2C stands for inter-integrated circuit and is a method designed to allow one chip to talk to another synchronously. The Raspberry Pi features in-built support for the I2C protocol allowing it to connect and talk with a variety of I2C capable circuits.
Does Raspberry Pi 4 have I2C?
We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 has six SPI controllers, six I2C controllers, and six UARTs – all on its 40-pin header.
How do I enable I2C on my Raspberry Pi?
Perform these steps on the Raspberry Pi Linux® terminal to ensure that the I2C interface is enabled in the hardware kernel.
- Run this command:
- Select Interfacing Options > I2C.
- Select Yes when prompted to enable the I2C interface.
- Select Yes when prompted to automatically load the I2C kernel module.
- Select Finish.
How does I2C work on Raspberry Pi?
The I2C bus allows multiple devices to be connected to your Raspberry Pi, each with a unique address, that can often be set by changing jumper settings on the module. It is very useful to be able to see which devices are connected to your Pi as a way of making sure everything is working.

How do I find my I2C device address?
- Find I2C address of your device. You can use i2cdetect or Explorer program to find current i2c address of your device.
- i2cdetect. Run: i2cdetect -y 1 [Press Enter] This program displays address in 7 bit format (multiply by 2 to get 8 bit format).
- Explorer Program. Navigate to appropriate folder. Run:
How do I read an I2C address?
A 7-bit I2C address includes a 7-bit slave address in the first 7 bits of a byte. The eighth bit (the bit in the Least Significant Bit position) is the read/write flag. A 0 in the eighth bit indicates a write and a 1 in the eighth bit signifies a read.
