Object Creation 

Anchor
object_creation object_creation

To create an storageinfo object, first load the brightsign/storageinfo module using the require() method. Then create an instance of the storageinfo class with a string value specifying the storage path.

var StorageInfoClass = require("@brightsign/storageinfo");
var storageInfo = new StorageInfoClass("/storage/sd");

Use the following string values to specify different storage drives:

• "/storage/usb1" – The drive for USB storage devices connected to the player

• "/storage/sd" – The primary SD or microSD drive on the player.

• "/storage/sd2" – The internal microSD drive on the player (4Kx42, XDx32 models only)

• "/storage/ssd" – The internal SSD on the player (XTx44, XTx43, XDx34, and XDx33 models only)

StorageInfo

Use this interface to retrieve information about the storage device.

getDeviceSize()

Promise <Number> getDeviceSize

Returns the total size of the storage device (in bytes).

getDeviceInfo()

Promise <StorageDeviceInfo> getDeviceInfo()

Returns a StorageDeviceInfo  interface containing manufacturer information about the storage device.

getDeviceHealth()

Promise<StorageDeviceHealth> getDeviceHealth()

Returns a "card wear" indication in the form of a percentage. This value is approximate and is provided to assist in scheduling proactive replacements to avoid in-field failures. Once this value reaches 100, the card is life expired and further attempts to write to the card may fail. This feature is only supported on certain industrial-type cards such as the Micron and Sandisk cards supplied by BrightSign.

StorageDeviceInfo

This interface contains manufacturer information about the storage device. Any of the below parameters may be absent from the interface depending on the device type and the information returned by the device:

• type string: Returns a string describing the type of filesystem used on the specified storage.

• sizeNumber

• : The total size of the storage device (in bytes)

• SDDeviceInfo sd [type == "SD"]

• : Returns details about the SD card hardware.

• SATADeviceInfo sata[type == "SATA"]

• : Returns details about the Serial ATA (SATA) interface.

SDDeviceInfo

• productName string: The product name, as assigned by the device manufacturer (5 bytes for SD, 6 bytes for MMC)

• oemID string: The two-character card OEM identifier as assigned by the SD Card Association

• auSize number

• optional

• : The size of the SD AU in bytes

• productRev string: The product revision assigned by the device manufacturer

• mfrDate string optional: The manufacture date reported by the storage device

• serial string optional: The serial number of the storage device

• signalVoltage string: The signal voltage reported by the SD card

• uhsMode string: The UHS mode (i.e. BUS speed) reported by the SD card

• specVersion Number

• : The version of SD spec to which the card conforms

• speedClass string optional: The speed class (if any) declared by the SD card

• mfrID Number

• : The card manufacturer ID as assigned by the SD Card Association

StorageDeviceHealth

• percentageHealthUsed int

• : Returns an integer that indicates the "wear percentage" of disk health used, on Micron and SanDisk storage cards that support this feature.

SATADeviceInfo

• sataModel String

• : The SATA model reported by the device

• sataVendor String

• : The SATA vendor reported by the device

Example

var storageClass = require("@brightsign/storageinfo");
var storage = new storageClass("/storage/usb1");


storage.getDeviceSize().then(
        function(data) {
            console.log(JSON.stringify(data));
        })
    .catch(
        function(data) {
            console.log(JSON.stringify(data));
        });

storage.getDeviceInfo().then(
        function(data) {
            console.log(JSON.stringify(data));
        })
    .catch(
        function(data) {
            console.log(JSON.stringify(data));
        });
