Assembly

Software

Flash Raspberry Pi OS to micro SD card. Then add following lines into config.txt:

gpu_mem=256
dtoverlay=rpi-display
display_rotate=2

For application, simply execute this script after boot:

from gpiozero import Button
from picamera import PiCamera
import time

button = Button(26)

with PiCamera() as camera:
    camera.resolution = (4056, 3040)
    camera.framerate = 5
    frame = int(time.time())
    camera.start_preview()
    while True:
        button.wait_for_press()
        camera.capture('/home/pi/Pictures/%03d.jpg' % frame)
        frame += 1
