Install All the Modules (Important)
=========================================

#. **Prepare the system**

   Make sure your Raspberry Pi is connected to the Internet, then update the system:

   ::

      sudo apt update
      sudo apt upgrade

   .. note::
      If you are using Raspberry Pi OS Lite, install the required Python 3 packages first:

      ::

         sudo apt install git python3-pip python3-setuptools python3-smbus

#. **Install robot-hat**

   Download and install the ``robot-hat`` module:

   ::

      cd ~/
      git clone -b 2.5.x https://github.com/sunfounder/robot-hat.git --depth 1
      cd robot-hat
      sudo python3 install.py

#. **Install vilib**

   Download and install the ``vilib`` module:

   ::

      cd ~/
      git clone https://github.com/sunfounder/vilib.git --depth 1
      cd vilib
      sudo python3 install.py

#. **Install picar-x**

   Download and install the ``picar-x`` module:

   ::

      cd ~/
      git clone -b 2.1.x https://github.com/sunfounder/picar-x.git --depth 1
      cd picar-x
      sudo pip3 install . --break

   This step may take a little while. Please be patient.

#. **Enable sound (I2S amplifier)**

   To enable audio output, run the ``i2samp.sh`` script to install the required I2S amplifier components:

   ::

      cd ~/robot-hat
      sudo bash i2samp.sh

   Follow the on-screen prompts by typing ``y`` and pressing Enter to continue, run ``/dev/zero`` in the background, and restart the Picar-X.

   .. note::
      If there is no sound after restarting, try running the ``i2samp.sh`` script several times.
