ljswitchboard-device_scanner

A node project dedicated to finding ALL LabJack devices that are able to be connected to. Uses LabJack-nodejs for LJM's scanning functionality as well as some special node additions.

findAllDevices

Takes an optional parameter of a list of connected device objects.

Returns an array,

• containing device types (T7/Digit/etc.) as objects, which includes an array "devices",
  • which contain discovered devices as objects grouped by device serial number, which contains an array of "connectionTypes",
    • which are objects describing how each discovered device is available

findAllDevices return example and format:

    "deviceTypeString": "LJM_dtT7",
    // The LJM device type
