A collection of various programs that run on a custom circular display.

To build and deploy to a Raspberry Pi:

1. Install Odin compiler on local machine.
2. Update Makefile HOST and HOME variables.
3. Run make dependencies to install dependencies on Raspberry Pi.
4. Run make deploy to build and upload to Raspberry Pi.
5. Add .env file with following information:

HA_URL=
HA_MEDIA_ENTITY=
HA_TOKEN=

6. Start the program using sudo systemctl start portal.service

To enable auto-start on boot:

1. Enable console auto-login via sudo raspi-config (System Options > Auto Login > Console Autologin)
2. Run sudo systemctl enable portal.service.
3. Use client.sh to remotely change the scene.

To prevent SD card wear, configure logging to RAM (/run/log/journal)

1. Enable journald volatile storage with memory limits:

# /etc/systemd/journald.conf
Storage=volatile
RuntimeMaxUse=50M
RuntimeKeepFree=10M

2. Restart journald: sudo systemctl restart systemd-journald
3. Verify configuration: journalctl --disk-usage

Audio capture is not working or very quiet.

1. Check if microphone is detected: arecord -l.
2. Use amixerto increase the microphone gain. Note, this is device-dependent; reduce the percentage if the input is too noisy. (e.g., sudo amixer -c 0 sset 'Mic' 90%)
