Now that we have I2C enabled on our device, let us test that it is detecting connections. (Of course you may have guessed by looking at our product offerings that we are admittedly a little biased. The i2c-tools package allows us to interact with the I2C protocol on our Raspberry Pi. 2. On Raspbian, you will find this file directly in /boot/config.txt. However, don’t forget that many users don’t connect any screen to their Raspberry-Pi (personally I never used the Raspbian OS desktop). Please note that this command differs if you are using the very first Raspberry Pi. Not only is the Raspberry Pi 4 bursting with new hardware features but under the hood there are some extra GPIO functions to make life a bit easier, allowing users to expand their peripherals to their projects without requiring additional hardware In particular there are a bunch of extra I2C, UART and SPI interfaces that can be used on the Raspberry Pi 4. If that fails to work, then you may have a faulty device. Resistors* 5. Breadboard* 6. If you have run into any issues or have any feedback, then feel free to leave a comment below.

I2C is a multi-drop bus, multiple devices can be connected to these same two pins. Disclaimer & Privacy Policy | About us | Contact. All done. So, since the Raspberry Pi can talk I2C we can connect it to a variety of I2C capable chips and modules. These numbers represent the address in which your I2C device can be accessed. Or on the PI 4 just use the desktop raspberry icon to open “Preferences”, then “Raspberry Pi Configuration”, and select the “Interfaces” tab, then click enable for the I2C. Raspberry Pi Zero WH (with Header) I2C 1602 Serial LCD for Arduino & RPI . 2. Launch the config tool by running the following command. Once your Raspberry Pi has finished updating, we can install the I2C tools and the Python SMBus package. This page contains all the options for the serial interfaces that the Raspberry Pi supports. In all 256M Raspberry Pi models, the I2C user port is 0, and in rest, all it is 1.
