# Install libcamera dev and apps
./install_pivariety_pkgs.sh -p libcamera_dev
./install_pivariety_pkgs.sh -p libcamera_apps

# Install the Hawk-Eye kernel driver
./install_pivariety_pkgs.sh -p 64mp_pi_hawk_eye_kernel_driver

# Edit /boot/config.txt, and under [pi4] section, add this line:
dtoverlay=vc4-kms-v3d,cma-512

# After a reboot, take a picture with autofocus at 16 megapixels:
libcamera-still -t 5000 --viewfinder-width 2312 --viewfinder-height 1736 --width 4624 --height 3472 -o 16mp-autofocus-test.jpg --autofocus

# Or at 64 megapixels (default resolution):
libcamera-still -t 5000 --viewfinder-width 2312 --viewfinder-height 1736 -o 64mp-autofocus-test.jpg --autofocus

# Or just watch a preview with autofocus working:
libcamera-still -t 0 --viewfinder-width 2312 --viewfinder-height 1736 --autofocus

# Or play around with digital zoom:
libcamera-still -t 0 --viewfinder-width 2312 --viewfinder-height 1736 -k
# While preview is showing, go back to terminal and press:
# W: Zoom in
# S: Zoom out
# I: Move upward
# K: Move downward
# J: Move left
# L: Move right
# R: Reset
# M: 10x Zoom
# You have to press the character, then press 'Enter' for it to register.

# To use continuous autofocus:
libcamera-still -t 0 --viewfinder-width 2312 --viewfinder-height 1736 --continue-autofocus
# Note: This mode seems to have some quirks right now, in terms of when it re-focuses.
