Installation

Flash Rasbian Lite OS onto SD card
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>"
}
```
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
Boot up Raspberry Pi
SSH into the Raspberry Pi
- If setup over usb, it'll be ssh pi@raspberrypi.local
Run initial update commands
```
sudo apt -y update
sudo apt -y upgrade
```
Enable the camera (If using CSI camera port) with sudo raspi-config -> Interfacing Options -> Camera
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
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
Install FFmpeg with sudo apt install ffmpeg
Setup python
- Run sudo apt install python3-pip python3-gpiozero
- Install the python requirements sudo pip3 install -r /opt/rpic/requirements.txt

Setup the i2s mic

    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

Setup for switching to AP Mode

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
