This module data upgrade adds C8051 reference programs compiled under Keil and Cameron test reference drawings, while providing STM32 IO directly driven routines. Attached information: register configuration example(QVGA, RGB565 output format, lighting mode), camera module application guide, data manual, ov7670 schematic diagram, PCB size diagram, sccb interface data, C8051f drive routine.Please contact us if you need.
This image sensor, small in size and low in voltage, provides all the functions of a single VGA camera and image processor. Through the SCCB bus control, various resolution 8-bit data can be output for the entire frame, sub-sampling, and window retrieval. The product VGA image up to 30 frames per second. Users can fully control image quality, data format and transmission methods. All image processing functions, including gamma curves, white balance, saturation, Chromaticity, etc., can be programmed through the SCCB interface.
Camera 100% inspection before the factory to ensure quality.
