While the single-board computer Raspberry Pi can perform complex tasks (eg hosting of database and WebServer) as a full-value computer, the Arduino microcontroller can take care of the fast signal pre-processing. To configure the software, we will add the Pi user to the I2C access group, by running. The other package needed can be installed by running sudo apt-get install python-smbus. The first command to run is sudo apt-get install i2c-tools.If this fails, try running sudo apt-get update and try again, else run crying to your nearest nerd. There are a few packages that will need installing to use I2C. Two examples of I2C capable circuits that we have used in our Raspberry Pi projects before are the VEML6075 UV Sensor and the. The Raspberry Pi features in-built support for the I2C protocol allowing it to connect and talk with a variety of I2C capable circuits. Note that these pins already have a 1.8 kilo-ohm pull-up resistors in them.I2C stands for inter-integrated circuit and is a method designed to allow one chip to talk to another synchronously. There is another set of I2C pins (I2C-0) at 27 and 28 but they are reserved for communicating with EEPROMs found in Raspberry Pi HATs. Raspberry Pi I2C Pins The I2C pins SDA and SCL are in pins 3 and 5 of the Raspberry Pi's header: This is I2C port 1 or simply I2C-1.
