The camera is tested before leaving our factory. The purpose is to
ensure the quality to prevent problems from causing various
troubles to both parties. We only explains the related problems of
the c8051 driver. If customer chooses the mcu by themself , we do
not know the hardware situation and cannot explain it!

3V3-----input power supply voltage (3.3 is recommended, you can
also use 5V ,but not recommended)
GDN-----Grounding point
SIO_C---SCCB interface control clock (note: some low-level MCUs
require pull-up control, similar to I2C interface)
SIO_D---Serial data input (output) end of SCCB interface (Note:
Some low-level MCUs need pull-up control, which is similar to I2C
interface)

OV7670 image sensor, small size, low working voltage, provides all
the functions of a single-chip VGA camera and image processor.
Through SCCB bus control, it can output 8-bit impact data with
various resolutions such as whole frame, sub-sampling, and
windowing. The VGA image of this product reaches 30 frames per
second. Users can fully control the image quality, data format and
transmission method. All image processing functions including gamma
curve, white balance, saturation, chroma, etc. can be programmed
through the SCCB interface.
High sensitivity suitable for low illumination applications
Low voltage suitable for embedded applications
Standard SCCB interface, compatible with I2C interface
RawRGB, RGB (GRB4:2:2, RGB565/555/444), YUV (4:2:2) and YCbCr
(4:2:2) output formats
