Detailed Description

Implementation of a HWBridge for the USBDMX.COM interface.

This implementation uses the D2xx driver library as opposed to the VCP drivers

This in interface supports both TX and RX at the same time

Member Function Documentation

- (id) initWithIdentifier:

(NSString *)

identifier

Open a specific DMX Interface, and initlise it ready for use.

Parameters:

identifier

The identifier to the device driver of the interface

A bridge should always be obtained via the hardware manager, and not directly.

YOU SHOULD NEVER NEED TO CALL THIS FUNCTION.

Returns:

The HW Bridge

See also:

LOHWManager

+ (NSArray *) interfaceIdentifiers

Get a list of all possible hardware interfaces.

These identifiers can be passed into initWithIdentifier:

Returns:

An Array (as NSString objects) of identifiers

- (unsigned char) versionByte

Get the versino byte for the interfacxe.

- (NSString *) versionString

Get the version (copyright) string.
