Public Methods

Method	Description
AddDevice ( Primitive, VID, Primitive, PID, Primitive, name ) : Primitive,	Add a HID connected device from its VID and PID. The VID and PID are 4 character (hex) values, and can be found from: Device Manager->Properties->Details->Hardware ids For example: HID\VID_046D PID_C215 REV_0204 has VID "046D" and PID "C215". Only add a device once.
FindDevices ( ) : Primitive,	List all found HID (Human Interface Devices).
GetBits ( Primitive, data ) : Primitive,	Get an 8 element array of 1s and 0s indicating which bit of a byte are set.
InputLength ( Primitive, name ) : Primitive,	Get the input record length for a HID device.
Output ( Primitive, name, Primitive, data ) : Primitive,	Send data to the HID device. This must be an array of bytes (0 to 255). The array must be indexed from 1 and have size OutputLength.
OutputLength ( Primitive, name ) : Primitive,	Get the output record length for a HID device.
SetBits ( Primitive, data ) : Primitive,	Set a byte from an 8 element array of 1s and 0s indicating which bit of a byte are set.

Method Details

AddDevice() public static method

Add a HID connected device from its VID and PID. The VID and PID are 4 character (hex) values, and can be found from: Device Manager->Properties->Details->Hardware ids For example: HID\VID_046D PID_C215 REV_0204 has VID "046D" and PID "C215". Only add a device once.

public static AddDevice ( Primitive, VID, Primitive, PID, Primitive, name ) : Primitive,
VID	Primitive,	The device VID.
PID	Primitive,	The device PID.
name	Primitive,	A name for the device.
return	Primitive,

FindDevices() public static method

List all found HID (Human Interface Devices).

public static FindDevices ( ) : Primitive,
return	Primitive,

GetBits() public static method

Get an 8 element array of 1s and 0s indicating which bit of a byte are set.

public static GetBits ( Primitive, data ) : Primitive,
data	Primitive,	A byte number (0 to 255).
return	Primitive,

InputLength() public static method

Get the input record length for a HID device.

public static InputLength ( Primitive, name ) : Primitive,
name	Primitive,	The device name.
return	Primitive,

Output() public static method

Send data to the HID device. This must be an array of bytes (0 to 255). The array must be indexed from 1 and have size OutputLength.

public static Output ( Primitive, name, Primitive, data ) : Primitive,
name	Primitive,	The HID device name.
data	Primitive,	The data to send.
return	Primitive,

OutputLength() public static method

public static OutputLength ( Primitive, name ) : Primitive,
name	Primitive,	The HID device name.
return	Primitive,

SetBits() public static method

Set a byte from an 8 element array of 1s and 0s indicating which bit of a byte are set.

public static SetBits ( Primitive, data ) : Primitive,
data	Primitive,	An 8 element array of 1s and 0s (small bit first).
return	Primitive,
