You may have a question: What do the installation scripts do when we install the server on the Raspberry Pi by them? So here let’s check the detailed steps.

1. Install pip.

apt-get install python-pip

2. Use pip to install django.

sudo pip install django

3. Install i2c-tools and python-smbus.

sudo apt-get install i2c-tools python-smbus –y

4. Install PiCar drivers.

cd ~/
git clone -–recursive https://github.com/sunfounder/SunFounder_PiCar.git
cd SunFounder_PiCar
sudo python setup.py install

5. Download source code.

cd ~/
git clone https://github.com/sunfounder/SunFounder_PiCar-V.git

6. Copy the MJPG-Streamer file to system directory.

cd ~/SunFounder_PiCar-V
sudo cp mjpg-streamer/mjpg_streamer /usr/local/bin
sudo cp mjpg-streamer/output_http.so /usr/local/lib/
sudo cp mjpg-streamer/input_file.so /usr/local/lib/
sudo cp mjpg-streamer/input_uvc.so /usr/local/lib/
sudo cp -R mjpg-streamer/www /usr/local/www

7. Export paths.

export LD_LIBRARY_PATH=/usr/local/lib/ >> ~/.bashrc
export LD_LIBRARY_PATH=/usr/local/lib/ >> ~/.profile
source ~/.bashrc

8. Enable I2C1.

Edit the file /boot/config.txt:

sudo nano /boot/config.txt

Add the line in the end:

dtparam=i2c_arm=ons

9. Reboot.

sudo reboot
