- class adafruit_ov2640.OV2640(i2c_bus, data_pins, clock, vsync, href, shutdown=None, reset=None, mclk=None, mclk_frequency=20000000, i2c_address=48, size=1)¶
Library for the OV2640 digital camera
i2c_bus (busio.I2C) – The I2C bus used to configure the OV2640
data_pins (List[microcontroller.Pin]) – A list of 8 data pins, in order.
clock (microcontroller.Pin) – The pixel clock from the OV2640.
vsync (microcontroller.Pin) – The vsync signal from the OV2640.
href (microcontroller.Pin) – The href signal from the OV2640, sometimes inaccurately called hsync.
shutdown (Optional[microcontroller.Pin]) – If not None, the shutdown signal to the camera, also called the powerdown or enable pin.
reset (Optional[microcontroller.Pin]) – If not None, the reset signal to the camera.
mclk (Optional[microcontroller.Pin]) – The pin on which to create a master clock signal, or None if the master clock signal is already being generated.
mclk_frequency (int) – The frequency of the master clock to generate, ignored if mclk is None, requred if it is specified
i2c_address (int) – The I2C address of the camera.
Capture an image into the buffer.
- property capture_buffer_size¶
Return the size of capture buffer to use with current resolution & colorspace settings
- property colorspace¶
Get or set the colorspace, one of the
Deinitialize the camera
- property exposure¶
The exposure level of the sensor
- property flip_x¶
Get or set the X-flip flag
- property flip_y¶
Get or set the Y-flip flag
- property height¶
Get the image height in pixels. A buffer of 2*width*height bytes stores a whole image.
- property mclk_frequency¶
Get the actual frequency the generated mclk, or None
- property product_id¶
Get the product id (PID) register. The expected value is 0x26.
- property product_version¶
Get the version (VER) register. The expected value is 0x4x.
- property size¶
Get or set the captured image size, one of the
- property width¶
Get the image width in pixels. A buffer of 2*width*height bytes stores a whole image.
