The associated register address for the sensor ID setting in the camera ov2685

OV2685:

chip_id

address:0x300a default:0x26

address:0x300b default:0x85

address:0x300c defailt:0x00

Back to the morning of the topic, if I want to check the ID of the camera, my code can write so, in the Gpl329a-sensor-id settings there is complete code, here I only give a small part:

Sensor_info.write_data[0] = 0x30;  SENSOR_INFO.WRITE_DATA[1] = 0x0a;  Sensor_info.write_size = 2;sensor_info.read_size = 2;ret = IOCTL (FD, I2c_bus_write_read, &sensor_info); if (Ret < 0 {<span style= "White-space:pre" ></span>perror ("IOCTL set i²c arg\n"); continue;} Readdevice = (Sensor_info.read_data[0] << 8) + sensor_info.read_data[1];//if (Readdevice = = 0x2656) if (Readdevice = = 0x2685) {DEBUG ("i2c_bus_write_read data = 0x%02x\n", readdevice); i = Max_device + 1;<span style= "White-space:pre" ></span>deviceno = 2;} else{printf ("Error i2c_bus_write_read data = 0x%02x\n", readdevice);}

Look at the code:

Sensor_info.write_data[0] = 0x30;  SENSOR_INFO.WRITE_DATA[1] = 0x0a;

The meaning of this structure array is to store the values of the two registers, and then to read the corresponding value of the address via the I²c bus, if the read value is 0x2685, this indicates that the device has been driven, and also read the corresponding ID number.
