Function Description: Used to demonstrate SDK initialization, get SDK version, get device model, get device serial number, get firmware version number, SDK resource release, and exit the program through the ESC_KEY key

| This example is based on the C Low Level API for demonstration

Firstly, get and print the current SDK version

printf("SDK version: %d.%d.%d\n", ob_get_major_version(), ob_get_minor_version(), ob_get_patch_version());

Create a Context for obtaining a list of device information and creating devices

ob_error*   error = NULL;
ob_context* ctx   = ob_create_context( &error );

Query the list of connected devices to get the number of devices in the list, and use index number 0 to create the first device in the list

ob_device_list* dev_list = ob_query_device_list( ctx, &error );
int dev_count = ob_device_list_device_count(dev_list, &error);
if(dev_count == 0) {
printf("Device not found!\n");
return -1;
}
ob_device* dev = ob_device_list_get_device(dev_list, 0, &error);

Next, you can get information related to this device

//Get device information
ob_device_info* dev_info = ob_device_get_device_info(dev, &error);

//Get device name
const char* name = ob_device_info_name(dev_info, &error);

//Get pid, vid, uid of the device
int pid = ob_device_info_pid(dev_info, &error);
int vid = ob_device_info_vid(dev_info, &error);
int uid = ob_device_info_uid(dev_info, &error);

//By get the firmware version number of the device
const char* fw_ver = ob_device_info_firmware_version(dev_info, &error);

//By get the serial number of the device
const char* sn = ob_device_info_serial_number(dev_info, &error);

//Get a list of supported sensors
ob_sensor_list* sensor_list = ob_device_get_sensor_list(dev, &error);

//Get the number of sensors
int count = ob_sensor_list_get_sensor_count(sensor_list, &error);
for(int i = 0; i < count; i++)
{
ob_sensor_type sensor_type = ob_sensor_list_get_sensor_type(sensor_list， i, &error);
switch (sensor_type)
{
case OB_SENSOR_COLOR:
break;
case OB_SENSOR_DEPTH:
break;
case OB_SENSOR_IR:
break;
}
}

Release resources and exit the program.

//Release sensor list
ob_delete_sensor_list(sensor_list, &error);
//Release device info
ob_delete_device_info(dev_info, &error);
//Release device
ob_delete_device(dev, &error);
//Release device list
ob_delete_device_list(dev_list, &error);
//Release context
ob_delete_context(ctx, &error);
