Just to get the data from camera, the I2C configurations has Start, Read, Write, Set Address function which are important when using  I2C protocol. The OV7670 is a FIFO camera. #define COM10_HSYNC         0x40  /* HSYNC instead of HREF */ #define REG_COM3    0x0c  /* Control 3 */   wrSensorRegs8_8(yuv422_ov7670); If not, you can send a screenshot showing the kind of images you are getting. Also note that closing the camera lens all the way will most likely cause you to have an out of focus image so try to unscrew it a little. MatanBright also shared his solution for interfacing with the Arduino Mega which I plan to look into.

The function sets the register values from register list which is predefined in the program.

Like many other people, I also couldn't get the OV7670 camera working directly with this code on my Arduino Uno.   { REG_HAECC3, 0xd8 }, { REG_HAECC4, 0xd8 }, #define REG_COM12   0x3c  /* Control 12 */ If the UNO gives 5V output to GPIO then use Level Shifter.
