6. Check I2C and SPI Interface

We will be using Raspberry Pi’s I2C and SPI interfaces. These interfaces should have been enabled when installing the robot-hat module earlier. To ensure everything is in order, let’s check if they are indeed enabled.

  1. Input the following command:

    sudo raspi-config

  2. Choose Interfacing Options by press the down arrow key on your keyboard, then press the Enter key.
