2. Installing the Code!!!

Part 1: Dependencies 

 The software relies on other programs to run smoothly. We'll install these now.  If not already, connect using PuTTY. 

 

 Install Main Dependencies

 sudo apt install git python3-xyz python3-pip python3-setuptools python3-flask -y

sudo pip install django-templates 

 

 Now, we're going to install the official PiCar-V code.

 cd ~/

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

 

 Enter the directory

 cd ~/SunFounder_PiCar-V	 

 

  Install smaller dependencies

 sudo ./install_dependencies 

 

 VERY IMPORTANT!!! REBOOT THE CAR 

 

 sudo reboot now 

 Part 2: Extra Settings 

 In this part, we'll enable I2C in the Pi's Config. This allows you to control the motors. Don't worry, this one's quick, and you're almost ready to drive :}}}} 

 

 Enter the Raspberry Pi config

 sudo raspi-config 

 

 Select interface options by pressing the number for the option using your keyboard. 

 Enable I2C by moving down to the option and pressing enter. 

 You can use "esc" to exit. 

 

 Part 3: Drivers and Services 

 If not already using the batteries, connect the Pi to the batteries. 

 Now, we'll install the drivers for the servos on the car, and we'll write some code to ensure the program runs on boot. 

 1. Navigate to the PiCar code directory 

 cd ~/SunFounder_PiCar-V 

 2. Run the Servo Setup Script - This will move servos in the car, so make sure it is on the floor in an open space . 

 picar servo-install 

 3. This next part sets up AutoStart for the remote control program. We'll make a new "service file" so the pi knows to start it after booting. 

 sudo nano /lib/systemd/system/PiCar.service 

 4. Paste the following code, then exit. 

 [Unit]

Description=PiCarServer

After=multi-user.target

[Service]

Type=idle

ExecStartPre=/bin/sleep 10

ExecStart=/usr/bin/python3 /home/pi/SunFounder_PiCar-V/remote_control/manage.py runserver 0.0.0.0:8000

[Install]

WantedBy=multi-user.target 

 5. Now we'll enable the service with the following commands. 

 sudo systemctl daemon-reload

sudo systemctl enable PiCar.service 

 DONE! The next page explains how to connect to the car.
