class camera.Camera

The class to control camera.

Usage:

import board import sdioio import storage import camera

sd = sdioio.SDCard( clock=board.SDIO_CLOCK, command=board.SDIO_COMMAND, data=board.SDIO_DATA, frequency=25000000) vfs = storage.VfsFat(sd) storage.mount(vfs, '/sd')

cam = camera.Camera()

buffer = bytearray(512 * 1024) file = open("/sd/image.jpg","wb") size = cam.take_picture(buffer, width=1920, height=1080, format=camera.ImageFormat.JPG) file.write(buffer, size) file.close()

Initialize camera.

deinit() → None

De-initialize camera.

take_picture(buf: circuitpython_typing.WriteableBuffer, format: ImageFormat) → int

Returns:

the number of bytes written into buf

Return type:

int
