Installation

1. Flash Rasbian Lite OS onto SD card
2. Enable SSH and wifi - https://www.raspberrypi.org/documentation/configuration/wireless/headless.md
   • Add a file named ssh
   • Add a file named wpa_supplicant.conf
   • For the wpa_supplicant.conf, set the contents to the below to establish and initial wifi connection to download what we need

     country=US
     ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
     update_config=1
     
     network={
         ssid="<Your Home WiFi Name>"
         psk="<Your Home WiFi Password>"
     }
     

3. Enable SSH over USB (Optional)
   • In config.txt append dtoverlay=dwc2 to the end
   • In cmdline.txt append modules-load=dwc2,g_ether on the same line after rootwait with a single space between the two.
     • NOTE: if you see something like quiet init=/usr/lib/raspi-config/init_resize.sh after rootwait, just insert it between the two, but still making sure there is a single space between everything
4. Boot up Raspberry Pi
5. SSH into the Raspberry Pi
   • If setup over usb, it'll be ssh pi@raspberrypi.local
6. Run initial update commands

   sudo apt -y update
   sudo apt -y upgrade
   

7. Enable the camera (If using CSI camera port) with sudo raspi-config -> Interfacing Options -> Camera
8. Setup the project's folder
   • Run sudo mkdir /opt/rpic
   • Run sudo chown pi:pi /opt/rpic
   • Run sudo mkdir /opt/i2smic
   • Run sudo chown pi:pi /opt/i2smic
9. Add the project code to the Raspberry
   • Install git onto the raspberry sudo apt install git
   • Run git clone https://github.com/Turkey2349/RPIC-Record-and-Stream.git /opt/rpic
10. Install FFmpeg with sudo apt install ffmpeg
11. Setup python
    • Run sudo apt install python3-pip python3-gpiozero
    • Install the python requirements sudo pip3 install -r /opt/rpic/requirements.txt
12. Setup the i2s mic
    • Run

        sudo pip3 install --upgrade adafruit-python-shell
        wget https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/i2smic.py -P /opt/i2smic
        sudo python3 /opt/i2smic/i2smic.py
    

13. Setup for switching to AP Mode
    • Run sudo nano /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
      • Set the filecontents to

      country=US                          
      ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev                           
      update_config=1                     
      ap_scan=1
      
      ### your hotspot ###        # has to be the first network section!
      network={
          priority=0              # Lowest priority, so wpa_supplicant prefers the other networks below 
          ssid="<accesspoint>"    # your access point's name 
          mode=2 
          key_mgmt=WPA-PSK 
          psk="<passphrase>"      # your access point's password 
          frequency=2462
      }
      
      ### your network(s) ###    
      network={
          ssid="<yourWifi>"
          psk="<passphrase>"
      } 
      

    • Run sudo mkdir /opt/auto-hotspot
    • Run sudo git clone https://github.com/0unknwn/auto-hotspot.git /opt/auto-hotspot
    • Run cd /opt/auto-hotspot
    • Run sudo chmod +x auto-hotspot install.sh
    • Run sudo ./install.sh
14. Setup as service for on startup
    • Run sudo nano /etc/systemd/system/camera.service
    • File contents:

      [Unit]
      Description=RPIC Record and Stream service
      After=multi-user.target
      
      [Service]
      Type=simple
      ExecStart=/usr/bin/python3 /opt/rpic/main.py
      
      [Install]
      WantedBy=multi-user.target
      

    • Run sudo systemctl enable camera
    • Run sudo systemctl start camera
