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 --depth=1 https://github.com/sunfounder/robot-hat.git
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 picrawler

Then download the code and install picrawler module.

cd ~/
git clone --depth=1 https://github.com/sunfounder/picrawler.git
sudo pip3 install ~/picrawler --break-system-packages

This step will take a little time, so 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.
