3 I2C Interface
The I2C interface is directly connected to the image sensor OV2640. The OV2640 I2C slave
address is 0x60 for write and 0x61 for read. User can use I2C master to read and write all the
registers in the OV2640 sensor. For more information about the OV2640 register, please refer the
OV2640 datasheet. The Figure 5 shows writing value 0x01 to the OV2640 register 0xFF. The
Figure 6 shows reading value 0x26 from the OV2640 register 0x0A.
