Camera OV7670 via arduino

About

This project make photo using Arduino Uno andOV7670 model and send it into Serial port.
It's possible to configure image properties in file src/ExampleUart.cpp
To get images fill in the firmware into Arduino Uno and afterwards run read_img_from_serial.py

Pinout

• Power supply
  • 3.3V -> 3.3V
  • GND -> GND
• Camera Control Bus (SCCB) - I2C interface
  • SIOC -> A5 (with 10k pull-up resistors)
  • SIOD -> A4 (with 10k pull-up resistors)
• Camera settings
  • Reset -> 3.3V (Reset Signal. Active low.)
  • PWDN -> GND (Power Down Mode Selection. Active high.)
• Getting image dependencies
  • VSYNC -> D2 (Vertical Sync Output – Low during frame)
  • HREF -> none (Horizontal Reference – High during active pixels of 1 row)
  • XCLK -> D12 (Pixel Clock Output – Data is valid on rising edge)
• DCMI (Digital Camera Interface) - 8-bit Video Component Digital Output
  • D0-D3 -> A0-A3
