roUsbFilesystem

This object allows supported BrightSign players to expose a local file as a USB mass storage device when connected to a USB host port on another device (for example, a PC or television.) The host acts as if it is talking to a USB thumb drive or USB hard drive, but the reads and writes go to the specified local file on the BrightSign. It requires a file containing a filesystem. One way to make such a file is:

dd if=/dev/zero of=/storage/sd/test.img bs=4k count=2k
mkfs.vfat /storage/sd/test.img

Normally the local file would be prepared beforehand with a filesystem offline (any method that captures a raw copy of a filesystem should work).

BrightSign players with USB-C (except for LS3 and LS4) can use this object.

ifUsbFilesystem

Enable(filename As String) As Boolean

Expose an existing filesystem image as a USB mass storage device.

Disable() As Boolean

Remove an existing filesystem image as a USB mass storage device.

Examples

To create a filesystem (using the file from the example above):

fs = CreateObject("roUsbFilesystem")
result = fs.Enable(

{filename: "SD:test.img"}

)

The result is a boolean. A result of true means that the filesystem has been successfully created.

To remove a filesystem:

result = fs.Disable()
